C developer board with RISC-V and GCC

OMDAZZ with FPGA CycloneIV EP4CE6E22C8N. This FPGA contains only 6000 logic elements and 270 KBytes of RAM. Such limited resources formed the requirements for the project parameters: 16 KB of RAM and a text graphics adapter.

In resuld you can get RISC-V board with text display and PS/2 keyboard to run simple C application without operation system (like old computer).

The board use YRV CPU, which descriped in book Inside an Open-Source Processor ISBN 978-3-89576-443-1

You need fresh version of Intel Quartus to synthese project.

The demo program is Tetris. It use C and you can undestand how int works to see sources on github.
