Re:LibreRPi – open source replacements for RPi firmware by cleverca22 on Thursday September 15, 2022 @09:38AM (#32851749)
yep, thats why ive been focusing a lot on porting linux drivers over to little-kernel on the vpu, and getting things working without linux

https://www.youtube.com/watch?v=l7lIewA9fm4 is an example of a VPU accelerated mandelbrot, without the arm core even being turned on

for (int i=0; i<16; i++) { int temp = a[i] * b[i]; if (store) c[i] = temp; if (accumulate) accumulator[i] += temp; }

basically, the VPU can run this entire line of code in just 2 clock cycles, and this isnt even the 3d core, which is entirely seperate and more complex
