Xilinx’s UltraScale vs Arria 10 – Non dolet, Paete

Xilinx’s UltraScale vs Arria 10 – Non dolet, Paete
by Luke Miller on 03-18-2014 at 9:30 pm

The DSP48E2 (I do not come up with these names… Could have named it a multiplier thingy) in the Xilinx 20nm UltraScale family (I do not come up with these names… Could of named it Virtex-8, or Luke-8) is simply amazing. Today was good, as I began playing with UltraScale tools and seeing how the DSP checks out. I also encourage you to check… Read More

When we last visited texture compression technology for OpenGL ES on mobile GPUs, we mentioned Squish image quality results in passing, but weren’t able to explore a key technology at the top of the results. With today’s introduction of the ARM Mali-T720 GPU IP, let’s look at the texture compression technology inside: Adaptive… Read More

Imagination’s New GPU Cores
by Paul McLellan on 01-06-2014 at 9:00 am

This morning Imagination announced their latest GPU cores, including the world’s smallest fully-featured OpenGL ES3.0/OpenCL GPU core. More on that below. And it is the Internet…and graphics…so cats. Graphically rendered cats.

The first core is a a high end core new generation PowerVR Series6XT architecture… Read More

Increasingly, a GPU is misnamed as a “graphics” processing unit. They are really specialized architecture highly parallel compute engines. You can use these compute engines for graphics, of course, but people are inventive and find ways of using GPUs for other tasks that can take advantage of the highly parallel… Read More

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

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 to Benchmark a Processor
by Paul McLellan on 08-15-2013 at 2:11 am

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

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

Static Low-Power Verification in Mixed-Signal SoC Designs
by Daniel Payne on 06-19-2013 at 2:02 pm

IC designer Shubhyant Chaturvediof AMD used EDA tools from Mentor Graphicsand Concept Engineeringto perform static, low-power verification of a mixed-signal SoC design with a combined CPU and GPU. Shubhyant presented a poster session at DAC two weeks ago in Austin, and I wanted to share it with my readers here at SemiWiki.… Read More
