Does the evil sounding phenomenon known as Dark Silicon create a big opportunity for FPGA vendors as was predicted recently by Pacific Crest Securities? John Vinh posits that using multiple cores as a method of scaling throughput is flattening out, and the use of FPGA’s to perform computation can help off-load and thus overcome… Read More

SoCs in New Context Look beyond PPA
If we look back in the last century, performance and area were two main criteria for semiconductor chip design. All design tools and flows were concentrated towards optimizing those two aspects. As a result, density of chips started increasing and power became a critical factor. Now, Power, Performance and Area (PPA) are looked… Read More
Rest in Peace CPUs, Hello FPGAs
FPGAs in many ways are still a bit mysterious to some folk. I was at a high level summit in April, and I realized that many there had no idea what an FPGA was. They knew at least what a CPU was or meant and that their kids talk about GPUs. A good analogy I have for an FPGA when compared to a CPU is something like this. Think of the FPGA and CPU as … Read More
Imagination Has More Stuff Than You…Imagine
Imagination seems to be well known for a couple of things. Firstly, everyone knows that it is the graphics processor used in the iPhone and the iPad and lots of other phones. And they know that Imagination acquired MIPS at the start of this year.
But what people don’t seem to really appreciate is just what a huge portfolio of IP… Read More
FPGAs The Life Savers
Silicon dominates our lives, CPU’s, GPU’s are in the limelight but the unsung hero is the FPGA. They simply do the work where other silicon dare not tread, as they are unfit for the task. Never send a boy to do a man’s job.
For a moment, if we can, just for a few minutes perhaps we can break away from the social media bubble… Read More
How to Benchmark a Processor
How do you benchmark a processor? It seems like it should be easy, just run some code and see how fast it is. Traditionally processors were indeed benchmarked by raw performance like GMACS, GFLOPS, memory bandwidth and so on. But in today’s world where systems have become very complex and applications very compute intensive, the… Read More
♫ IMG Sitting on the DOK of the Bay…Closin’ Timin’
Scott Fitzgerald is supposed to have said “the rich are not like other people” to Ernest Hemingway (he didn’t). In the same way, processors are not like other blocks, and not because they have more gates (they don’t). However, special approaches to optimizing processors are important because the clock… Read More
ARM Partners with Carbon on Cortex-A57
Just in time for DAC, Carbon have announced that they have expanded their partnership with ARM to create and deliver models for the ARM Cortex-A57 processor and related IP. One piece of related IP is the Cortex-A53 which can be configured in big.LITTLE multi-core setups to achieve the sweet spot of higher performance and lower power.… Read More
Linley Tech Mobile Conference
I went to part of the Linley Tech Mobile Conference. This is the current incarnation of what started life as Michael Slater’s Microprocessor Report, and the twice-yearly Microprocessor Forum. These very technical analysis organizations seem to work well when they are a small group of analysts working together to cover… Read More
