PicoPU

A mecha project focused on building a very simple open-source General Purpose Graphics Processing Unit (GPGPU) using the amazing rp2350 MCUs as compute cores. The project it self is made of multiple parts: the software drivers, the GPU firmware and the hardware PCB itself.

The project is currently very WIP, more is to come.

Monorepo subprojects:

• core-firmware/ - PicoPU firmware
  • common/ - shared firmware utilities
  • usbd/ - a protocol generic tinyusb device driver
  • dvid/ - a simple hstx-based dvi driver
  • gcs/ - an arch agnostic software renderer
  • arch/ - device architecture specific source files
    • mockbird/ - RPi Pico 2 (mocking bird) arch firmware
• pdrv/ - a user-space host-side driver written in go
  • bench/ - an example application using directly pdrv apis
• boards/ - EasyEDA Std design files
  • broker - Files for the Broker/Motherboard
  • shader - Files for the smaller Shader boards
