  • Apparatus and method for native mode processing in a RISC-based CISC processor
    Patent number: 5909567
    Abstract: A processor reduces or avoids a degradation of computing performance in a computer system using a RISC-based CISC processor by selectively bypassing a CISC-to-RISC translator or decoder and supplying native RISC codes directly to the RISC core. The processor that executes CISC-type instructions on a RISC core includes a native mode Op supply circuit for supplying RISC Ops directly from an instruction memory to a RISC execution engine.
