New QPU macro assembler

Since Broadcom released complete documentation for the VideoCore IV GPU back in February 2014 we’ve seen a number of fun uses of our 24GFLOPs of QPU compute, from Andrew Holme’s FFT library to Pete Warden’s deep learning experiments. It’s not unusual to see a 10x increase in performance over the ARM for algorithms with a decent amount of parallelism. A platform is only as good as its development tools, so it’s a great start to the New Year to see a new QPU macro assembler from Marcel Müller

More QPU magic from Pete Warden

Back in June, we mentioned Pete Warden’s port of the Deep Belief image-recognition SDK to the Pi, which used the VideoCore IV QPUs to provide an accelerated GEMM matrix-multiply function. Since then, Pete’s been optimizing his code, and has reduced the time required to process an image to 3 seconds (versus 20 seconds for the baseline ARM implementation and 6 seconds for his original QPU version). Classifying dogs and their balls In the spirit of “leaving a trail of breadcrumbs through the forest”, Pete has written up an excellent summary of his experiences here

GPGPU hacking on the Pi

You may have noticed a certain lack of blog action over the last few days. Unfortunately, while I’ve recovered from the curse of Nuttall (though I do sound a little more Sith than usual), Liz has now fallen victim. We hope normal service will be resumed on Monday

A birthday present from Broadcom

Two years ago today*, the Raspberry Pi Model B went on sale, selling 100,000 units on the first day. Since then, over 2.5 million Raspberry Pis have found homes with hobbyists, children and professional engineers around the world. Each Pi in this first pallet now has over 1250 friends
