FPGACode-ide -> IceSugar-riscv -> IceSugar-tv80 -> IceSugar-6502
Here you will find a project for IceSugar implementing RISCV32. As well as full automation of assembly and testing. More detailed documentation on usage in the FPGACode-ide.
This project is based on the developments of picorv32
What is done:
- RAM: SPRAM or BRAM
- ROM: BRAM or SPI FLASH
- UART: MiniUart or RingUart
- todo: SPI: Classic spi
The commands can be executed manually in the terminal as well as through the Task menu in Code
