Abstract
An application-specific single chip digital processor having flexible design expansion capability with minimal impact on the performance of a processor core. The processor core has an ALU and a register file (accumulators). The output of the ALU is connected to a multiplexer whose output is connected to the input of the register file. The output of the register file connects to one input of the ALU. A function unit, separate from the core, has an input connected to the output of the register file and an output connected to another input to the multiplexer. The core operates with a predefined instruction set. The function unit, which may be redesigned depending on the application, operates with a reserved (uncommitted) instruction set under control of the core.
