The original value proposition was presented in the brief Brian Jeff highlights the ARM® Cortex™-A53 processor [ARMflix YouTube channel, Oct 30, 2012] video as follows

The Top 5 Things to Know about Cortex-A53 [Brian Jeff on ‘ARM Connected Community’, Oct 28, 2013]

The Cortex-A53 was introduced to the market in October 2012, delivering the ARMv8 instruction set and significantly increased performance in a highly efficient power and area footprint. It is available for licensing now, and will be deployed in silicon in early 2014 by multiple ARM partners. There are a few key aspects of the Cortex-A53 that developers, OEMs, and SoC designers should know:

1. ARM low power / high efficiency heritage

The ARM9 is the most licensed processor in ARM’s history with over 250 licenses sold. It identified a very important power/cost sweet spot.The Cortex-A5 (launched in 2009) was designed to fit in the CPU same power and area footprint,

    ARM926-based feature phone (Nokia E60).

while delivering significantly higher performance and power-efficiency, and bring it to modern ARMv7 feature set – software compatibility with the high end of the processor roadmap (then Cortex-A9)

The Cortex-A53 is built around a simple pipeline, 8 stages long with in-order execution like the Cortex-A7 and Cortex-A5 processors that preceded it. An instruction traversing a simple pipeline requires fewer registers and switches less logic to fetch, decode, issue, execute, and write back the results than a more complex pipeline microarchitecture. Simpler pipelines are smaller and lower power. The high efficiency Cortex-A CPU product line, consisting of Cortex-A5, Cortex-A7, and Cortex-A53, takes a design approach prioritizing efficiency first, then seeking as much performance as possible at the maximum efficiency. The added performance in each successive generation in this series comes from advances in the memory system, increasing dual-issue capability, expanded internal busses, and improved branch prediction.

2. ARM v8-A Architecture

The Cortex-A53 is fully compliant with the ARMv8-A architecture, which is the latest ARM architecture and introduces support for 64b operation while maintaining 100% backward compatibility with the broadly deployed ARMv7 architecture. The processor can switch between AArch32 and AArch64 modes of operation to allow 32bit apps and 64bit apps to run together on top of a 64bit operating system. This dual execution state support allows maximum flexibility for developers and SoC designers in managing the rollout of 64bit support in different markets. ARMv8-A brings additional features (more registers, new instructions) that bring increased performance and Cortex-A53 is able to take advantage of these.

3. Higher performance than Cortex-A9: smaller and more efficient too

The Cortex-A9 features an out-of-order pipeline, dual issue capability, and a longer pipeline than Cortex-A53 that enables 15% higher frequency operation. However the Cortex-A53 achieves higher single thread performance by pushing a simpler design farther – some of the key factors enabling the performance of the Cortex-A53 include the integrated low latency level 2 cache, the larger 512 entry main TLB, and the complex branch predictor. The Cortex-A9 has set the bar for the high end of the smartphone market through 2012 – by matching and exceeding that level of performance in a smaller footprint and power budget, the Cortex-A53 delivers performance to entry level devices that was previously enjoyed by high-end flagship mobile devices – in a lower power budget and at lower cost. The graph below compares the single thread performance of the high efficiency Cortex-A processors with the Cortex-A9. At the same frequency, Cortex-A53 delivers more than 20% higher instruction throughput than the Cortex-A9 for representative workloads.

4. Supports big.LITTLE with Cortex-A57

The Cortex-A53 is architecturally identical to the higher performance Cortex-A57 processor, and can be integrated with it in a big.LITTLE processor subsystem. big.LITTLE enables peak performance and extreme efficiency by distributing work to the right-sized processor for the task at hand.

It is described in more detail here – Ten Things to Know About big.LITTLE

The diagram above shows Cortex-A53 combined with Cortex-A57 and a Mali-T628Graphics processor in an example system. The CCI-400 cache coherent interconnect allows the 2 CPU clusters to be combined in a seamless way that allows software to manage the task allocation in a highly transparent way, as described in <link – software>. The big.LITTLE system enables peak performance at low average power.

Cortex-A53 in ideal for use in a standalone use scenario, delivering excellent performance at very low power and area enabling new features to be supported in the low cost smartphone segments  Our new LITTLE processor packs a performance punch.

Read more about that in a somewhat humorous blog on Cortex-A53 from the product launch – ARM Cortex-A53 — Who You callin’ LITTLE?

5. Extensive feature set for broad application support

The Cortex-A53 includes a feature set that allows it to be configured and optimized through physical implementation tailored to mobile SoCs and to  scalable enterprise systems

Mobile Features	Enterprise Features
AMBA 4 ACE Coherent bus big.LITTLE processing (2 CPU Clusters) with CCI-400 interconnect	AMBA5 CHI Coherent bus Scalable to 4 or more coherent CPU clustersfor low-cost servers or networking infrastructure devices. 16-core systems with  CCN-504 or 32-core systems with CCN-508 – all on a single silicon die.
Small area, low power design Optimized for <150mW envelope	Small area, low power design. Likely still optimized for 150 mW. However, higher performance implementations can be used

ARM Cortex-A53 — Who You callin’ LITTLE? [Brian Jeff on ‘ARM Connected Community’, Oct 30, 2013]

I may only weigh in at just over half a square millimeter on die, but I can handle a heavy workload and I pack quite a processing punch, and frankly I’m tired of the lack of respect I get as a “LITTLE” processor. I am the Cortex^TM-A53 processor from ARM, some of you may have previously known me by my code name “Apollo”. Despite being three times as efficient as my big brother, the Cortex-A57, and delivering more performance than today’s current heavyweight champ the Cortex-A9, I am often overlooked.

Processor designers and consumers alike look to the big core, the top end MHz figure, and the number of big processors in the system when they evaluate devices like premium smartphones and tablets. What they don’t realize is that I’m the one running during most of the time the mobile applications cluster is awake, and I’m the one that will enable improvements in battery life even as delivered peak performance increases dramatically. It is high time that the LITTLE processor gets the respect and appreciation that is due.

I’m speaking not just for myself here, but for my close cousin the Cortex-A7. We’re built from the same DNA, so to speak, sharing the same 8-stage pipeline and in-order structure. We both consume about the same level of power on our respective production process nodes, and although I bring added performance and support 64-bit, we are both quite alike. We are 100% code compatible for 32-bit code after all. And yet we don’t get the respect we deserve. It is an injustice, really.

In high-end mobile devices, my cousin the Cortex-A7 is always telling me how everyone wants to hear about how fast the Cortex-A15 is in the system, how many Cortex-A15 CPUs are in the system, and how many Mali^TM GPU cores are built into the SoC. They don’t even notice if there are four Cortex-A7 cores in the design capable of delivering plenty of performance — more performance than a lot of smartphones in the market today.  They just expect battery life to improve without giving any credit to the LITTLE processor that makes it possible.

Well they will soon see… big.LITTLE processors are coming into the market next year, nearly sampling already, and the capability of the LITTLE processor will be in full view, let me tell you.

Oh, and another thing — in the enterprise space, what they call “big Iron” — there is almost no recognition of the worth of small processors there. Sure, new designs are considering LITTLE processors in many-core topologies with ARM’s CoreLink^TM Cache Coherent Network (CCN) interconnect, but look at the products that are deployed today — they are mostly based on big cores, the bigger the better. Nowhere is this more evident than in the server space, where IT managers brag about how big their server racks are. Just wait and see. New server processors are being developed based on ARM, where even my big brother the Cortex-A57 is about an order of magnitude smaller and lower power than the incumbent processors. I’m in a different weight class altogether, but I can hang with the big boys on total performance. Purpose-built servers using lots of Cortex-A53 cores can deliver even more aggregate performance in a given power and thermal envelope. But are we LITTLE cores getting much attention in servers today? No. Well just watch and see. In 2015 when the first Cortex-A50 series 64-bit processors are built for lower power servers, you won’t be able to help but notice that LITTLE processors can get key jobs done in a lot less energy.

So I may be the same size relative to my Cortex-A57 big brother as the Cortex-A7 is to the Cortex-A15, but OEMs and consumers better not underestimate me. I’ve been going through intensive work these past 2 years to build up my muscles in the places that count: my SIMD performance is way up thanks to the improved NEON^TM architectural support in ARMv8 and a much wider NEON datapath. I can dual-issue almost anything. My memory system is also juiced up, as is my branch predictor capability. That’s how I can pack a bigger punch than Cortex-A9 at around a quarter the power in our respective process nodes.

That’s all I’m saying, man. You gotta respect the LITTLE processor.

Peace.

AnandTech Live with ARM’s Peter Greenhalgh [anandshimpi YouTube channel, Dec 20, 2013]

From the earlier: Answered by the Experts: ARM’s Cortex A53 Lead Architect, Peter Greenhalgh [AnandTech, Dec 17, 2013]

Cortex-A53 has been designed to be able to easily replace Cortex-A7. For example, Cortex-A7 supports the same bus-interface standards (and widths) as Cortex-A7 which allows a partner who has already built a Cortex-A7 platform to rapidly convert to Cortex-A53.

A Cortex-A53 cluster only supports up to 4-cores. If more than 4-cores are required in a platform then multiple clusters can be implemented and coherently connected using an interconnect such as CCI-400. The reason for not scaling to 8-cores per cluster is that the L2 micro-architecture would need to either compromise energy-efficiency in the 1-4 core range to achieve performance in the 4-8 core range, or compromise performance in the 4-8 core range to maximise energy-efficiency in the 1-4 core range.

We expect to see a range of platform configurations using Cortex-A53. A 4+4 Cortex-A53 platform configuration is fully supported and a logical progression from a 4+4 Cortex-A7 platform.

We’re pretty happy with the 8-stage (integer) Cortex-A53 pipeline and it has served us well across the Cortex-A53, Cortex-A7 and Cortex-A5 family. So far it’s scaled nicely from 65nm to 16nm and frequencies approaching 2GHz so there’s no reason to think this won’t hold true in the future.

Cortex-A53 has the same pipeline length as Cortex-A7 so I would expect to see similar frequencies when implemented on the same process geometry. Within the same pipeline length the design team focussed on increasing dual-issue, in-order performance as far as we possibly could. This involved symmetric dual-issue of most of the instruction set, more forwarding paths in the datapaths, reduced issue latency, larger & more associative TLB, vastly increased conditional and indirect branch prediction resources and expanded instruction and data prefetching. The result of all these changes is an increase in SPECInt-2000 performance from 0.35-SPEC/Mhz on Cortex-A7 to 0.50-SPEC/Mhz on Cortex-A53. This should provide a noticeable performance uplift on the next generation of smartphones using Cortex-A53.

Due to the power-efficiency of Cortex-A53 on a 28nm platform, all 4 cores can comfortably be executing at 1.4GHz in less than 750mW which is easily sustainable in a current smartphone platform even while the GPU is in operation.

The performance per watt (energy efficiency) of Cortex-A53 is very similar to Cortex-A7. Certainly within the variation you would expect with different implementations. Largely this is down to learning from Cortex-A7 which was applied to Cortex-A53 both in performance and power.

Intel to make ARM Processors, firstly 64bit 14nm ARM Cortex-A53 ARMv8 for Altera [Charbax YouTube channel, Oct 31, 2013]

Altera Announces Quad-Core 64-bit ARM Cortex-A53 for Stratix 10 SoCs [press release, Oct 29, 2013]

Manufactured on Intel’s 14 nm Tri-Gate Process, Altera Stratix® 10 SoCs Will Deliver Industry’s Most Versatile Heterogeneous Computing Platform

Santa Clara, Calif., ARM TechCon, October 29, 2013—Altera Corporation (NASDAQ: ALTR) today announced that its Stratix 10 SoC devices, manufactured on Intel’s 14 nm Tri-Gate process, will incorporate a high-performance, quad-core 64-bit ARM Cortex™-A53 processor system, complementing the device’s floating-point digital signal processing (DSP) blocks and high-performance FPGA fabric. Coupled with Altera’s advanced system-level design tools, including OpenCL, this versatile heterogeneous computing platform will offer exceptional adaptability, performance, power efficiency and design productivity for a broad range of applications, including data center computing acceleration, radar systems and communications infrastructure.

From: Intel fabs Altera’s Stratix 10 FPGA with four ARM A53 cores [SemiAccurate, Nov 5, 2013]: Altera representatives at Techcon said that the beast would tape out in Q4/2014 or about a year from now. From: Pigs Fly. Altera Goes with ARM on Intel 14nm [SemiWiki.com, Oct 29, 2013]: I asked Altera about the schedule for all of this. Currently they have over 100 customers using the beta release of their software to model their applications in the Stratix 10. They have taped out a test-chip that is currently in the Intel fab. In the first half of next year they will have a broader release of the software to everyone. They will tape out the actual designs late in 2014 and have volume production starting in early 2015. Why did they pick this processor? It has the highest power efficiency of any 64-bit processor. Plus it is backwards compatible with previous Altera families which used (32-bit) ARM Cortex-A9. The A53 has a 32-bit mode that is completely binary compatible with the A9. As I reported last week from the Linley conference, ARM is on a roll into communications infrastructure, enterprise and datacenter so there is a huge overlap between the target markets for the A53 and the target markets for the Stratix 10 SoCs.

The ARM Cortex-A53 processor, the first 64-bit processor used on a SoC FPGA, is an ideal fit for use in Stratix 10 SoCs due to its performance, power efficiency, data throughput and advanced features. The Cortex-A53 is among the most power efficient of ARM’s application-class processors, and when delivered on the 14 nm Tri-Gate process will achieve more than six times more data throughput compared to today’s highest performing SoC FPGAs. The Cortex-A53 also delivers important features, such as virtualization support, 256TB memory reach and error correction code (ECC) on L1 and L2 caches. Furthermore, the Cortex-A53 core can run in 32-bit mode, which will run Cortex-A9 operating systems and code unmodified, allowing a smooth upgrade path from Altera’s 28 nm and 20 nm SoC FPGAs.

“ARM is pleased to see Altera adopting the lowest power 64-bit architecture as an ideal complement to DSP and FPGA processing elements to create a cutting-edge heterogeneous computing platform,” said Tom Cronk, executive vice president and general manager, Processor Division, ARM. “The Cortex-A53 processor delivers industry-leading power efficiency and outstanding performance levels, and it is supported by the ARM ecosystem and its innovative software community.”

Leveraging Intel’s 14 nm Tri-Gate process and an enhanced high-performance architecture, Altera Stratix 10 SoCs will have a programmable-logic performance level of more than 1GHz; two times the core performance of current high-end 28 nm FPGAs.

“High-end networking and communications infrastructure are rapidly migrating toward heterogeneous computing architectures to achieve maximum system performance and power efficiency,” said Linley Gwennap, principal analyst at The Linley Group, a leading embedded research firm. “What Altera is doing with its Stratix 10 SoC, both in terms of silicon convergence and high-level design tool support, puts the company at the forefront of delivering heterogeneous computing platforms and positions them well to capitalize on myriad opportunities.”

By standardizing on ARM processors across its three-generation SoC portfolio, Altera will offer software compatibility and a common ARM ecosystem of tools and operating system support. Embedded developers will be able to accelerate debug cycles with Altera’s SoC Embedded Design Suite (EDS) featuring the ARM Development Studio 5 (DS-5™) Altera® Edition toolkit, the industry’s only FPGA-adaptive debug tool, as well as use Altera’s software development kit (SDK) for OpenCL to create heterogeneous implementations using the OpenCL high-level design language.

“With Stratix 10 SoCs, designers will have a versatile and powerful heterogeneous compute platform enabling them to innovate and get to market faster,” said Danny Biran, senior vice president, corporate strategy and marketing at Altera. “This will be very exciting for customers as converged silicon continues to be the best solution for complex, high-performance applications.”
