PROCESSING ARCHITECTURES WITH TYPED INSTRUCTION SETS

摘要

An architecture for microprocessors, in which instructions include a type identifier, selects one of several interpretation registers. The interpretation registers hold information for interpreting the opcode of each instruction, so that a stream of compressed instructions (with type identifiers) can be translated into a stream of expanded instructions. Preferably the type identifiers also distinguish sequencer instructions from processing-element instructions, and can even distinguish among different types of sequencer instructions (as well as among different types of processing-element instructions).
