Dr DSP, I fully agree that this study should be expanded to GPUs and DSPs. Just have not found the time yet. These theoretical designs also need to be placed and routed to make sure my assumptions match reality. You're also correct that the external memory connected to the FPGAs can play an important role in the true performance, but which FPGA board design do I use? This quickly grows into a large can of worms.

I just emailed Dave at Cray asking him to respond -- Max

This study should compare GPUs too! The memory interface speed can make a big difference too. FPGAs really need lots of external memory to keep up with the processing. I hope that is included somehow as well.

Have you had any real-world experience with regards to floating-point performance comparisons between FPGAs and microprocessors?

David Patterson, known for his pioneering research that led to RAID, clusters and more, is part of a team at UC Berkeley that recently made its RISC-V processor architecture an open source hardware offering. We talk with Patterson and one of his colleagues behind the effort about the opportunities they see, what new kinds of designs they hope to enable and what it means for today’s commercial processor giants such as Intel, ARM and Imagination Technologies.
