Enhanced Harvard Architecture Reduced Instruction Set Computer (RISC) with Debug Mode Access of Instruction Memory within a Unified Memory Space

A Harvard-architecture computer simultaneously reads instructions using an instruction bus and accesses data over a separate data bus. A debug module has an external interface to an external debugger that initiates a debugging session by setting a debug bit in a debug mode register. When the debug bit is set, a first mux to disconnect an instruction pointer and an instruction buffer from the instruction bus and instead connects the data bus to the instruction bus. A second mux disconnects a load / store unit in an execution core from the instruction bus and instead connects the debug module to the instruction bus. The external debugger sees a unified memory space and writes addresses to the debug module that are sent through the second mux to access the data memory, and instruction addresses are sent through the second mux and the first mux to the instruction memory to read or write instructions.
