Microcode Processor

A VHDL implementation of a microcode processor complete with microcoded control unit, datapath, and memory.

This project was created with the aid of Xilinx ISE Design Suite 14.7. To open the project in ISE, open the .xise project file.

The control memory contains the following operations:

ADD	-- add register values
ADI	-- add immediate value to register value
INC	-- increment register value
NOT	-- Logical not of register value
LD	-- load from memory into register
SR	-- store to memory from register
CMP	-- compare operands (subtract) and update status flags
JMP	-- unconditional jump
EQ	-- conditional jump, if Z = 1
LDI	-- load immediate value to register
