MCPU - Minimal CPU for a 32 Macrocell CPLD

MCPU is a minimal cpu aimed to fit into a 32 Macrocell CPLD - one of the smallest available programmable logic devices. While this CPU is not powerful enough for real world applications it has proven itself as a valuable educational tool. The source code is just a single page and easily understood. Both VHDL and Verilog versions are supplied. The package comes with assembler, emulator and extensive documentation.

This is an old project from 2001. Since it still seems to be of interest to many, I migrated it to Github for easier maintenance. Please refer to the original project description (pdf) for further information.”
