ABSTRACT:
A general purpose architecture for a digital microcomputer, which includes a central processing unit, random access memory, user-defined dedicated functions and an optional programmable read only memory. Instructions are fetched either externally or from the optionally ROM. Data can be fetched externally or internally. Each instruction fetched is interpreted by a general-purpose microengine. The architecture is flexible enough to permit the modular addition, deletion and modification of dedicated functions and microinstructions (including changes in execution timing and decoding), as well as the testing of memory independently from the rest of the architecture.
