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... Continue reading

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... Continue reading

Today we have some really big news, which is going to mean a lot to many programmers in our community who have been asking about it ever since launch. This is one of those announcements that has been in the pipeline for quite some time, but we haven’t been able to talk about it until... Continue reading
