MSc Digital System Lab (also check https://github.com/thomson008/microprocessor-rc/tree/master)

Verilog project of a simple microprocessor with peripherals such as mouse, VGA display and IR transmitter. Can be run on Xilinx Basys 3 FPGA board with an additional IR module in order to control a RC car. The system was developed for Digital Systems Laboratory course at The University of Edinburgh.

New features:

1. Text display

2. spirit

3. asm complier:

DSL_fpga_task-msc-/program_file/compiler.py

Line 1 in 3ce93e5

#!/usr/bin/env python3

ip:

1. block ram -> mcu ram
2. block rom -> mcu rom
3. block ram -> vga ram
4. block rom -> vga text tiles(ascii)
5. fifo -> vga data transfer

cpu: instruction
