Superscalar RISC Microprocessor Architecture with enhanced Multimedia Instructions

멀티미디어 명령어를 강화한 수퍼스칼라 RISC 마이크로프로세서 구조

For applications in multimedia to which genuine RISC microprocessors are not suitably applicable, a new generation of fast and flexible microprocessors is required. In this paper, as a technique of integrating DSP functionality in a general RISC processor, a RISC that can execute DSP extension instructions is developed to improve the performance of multimedia application execution. This processor can execute DSP instructions in parallel with the execution of ALU instructions for efficient and fast execution. In addition, the execution ability of integer instructions is improved by enhancing the RISC core itself.
