Microprocessor and method for executing high-level instructions

摘要

A microprocessor capable of executing a process instruction having at least one RISC type instruction is constructed to include an instruction decoding section for decoding a microcode including information which indicates transfer contents of input and output data and address information which indicates a storage location of the process instruction, a data reading section for reading input data corresponding to the information which indicates the transfer contents of the input and output data decoded by the instruction decoding section and reading the process instruction corresponding to the address information, and an operation process executing section for implementing one or a plurality of operation unit resources capable of executing an operation process according to the input data read by the data reading section and the process instruction.
