Hacking the Raspberry Pi's VideoCore IV GPU - Louis Howe

Louis Howe explores the architecture of the Raspberry Pi's VideoCore IV GPU and demonstrates live-coding a bare-metal assembly application.

Hacking the Raspberry Pi's VideoCore IV GPU for Fun, but Definitely Not for Profit. Talk by Louis Howe at pdxbyte 6/10/14. Let's delve into the murky, semi-open-source guts of the Pi's GPU! We'll explore its architecture, check out some sweet hacks and reverse-engineering efforts, and live-code a bare-metal QPU app in assembly. Whether you're on a mission for open hardware or just morbidly curious, come for a discussion of why anyone would spend their time digging into a closed firmware blob, as well as some speculation about the future of low-power hardware accelerators like the VideoCore.
