Research and Design of Superscalar Pipeline Processor Based on CPLD Technology

Superscalar pipelining is to improve instruction-level parallelism and advanced technology, and is widely used in the computer's central processor and graphic accelerator. In this paper, we made use of advantage of CPLD devicesinherent flexibility, usability, predictability and so on, to achieve superscalar pipelining, designed and constructed a processor model superscalar pipeline machine based on RISC instruction set. Using EDA technology with top-down design methods, and gave the processor model hardware verification and performance test results, and had explored the use of EDA technology processor design ideas and methods.
