Make a basic CPU using a cheap FPGA《CPU自制入门》
Sharing on the RTL design, hardware design, and software design of a basic CPU. The 32-bit RISC ISA is from the reference book《CPU自制入门》. This book is one of the best beginner books on CPU design, the end product of the book is the AZ Processor SoC which you can run on an actual hardware.
I ported the AZ Processor SoC to run on the cheapest Altera FPGA (EP2C5T144C8N FPGA development board). My GitHub repo (RTL, output files, assembler, assembly programs, slides etc.):
