The Multi-Port RAM Workspace for a Single- Chip Microcontroller utilizes a multi-port RAM, preferably in a single-chip environment, to produce a set of workspaces (equivalent to a set of register banks) allowing support for the typical RISC-like feature of a large bank of large registers without incurring the overhead delays associated with rapid context switching. Prior art has utilized the workspace concept, but incurred a performance penalty implementation from the isolated CPU and RAM structures available twenty years ago, forcing abandonment of the concept. Herein is a new architecture.
