with risc86 superskalarer microprocessor instruction set

摘要

An internal RISC-type instruction structure furnishes a fixed bit-length template including a plurality of defined bit fields for a plurality of operation (Op) formats. One format includes an instruction-type bit field, two source-operand bit fields and one destination-operand bit field for designating a register-to-register operation. Another format is a load-store format that includes an instruction-type bit field, an identifier of a source or destination register for the respective load or store operation, and bit fields for specifying the segment, base and index parameters of an address.
