Soft-core processor with MIPS R3000 compatible instruction set and its applications

摘要

We developed a soft-core processor IP which has instruction set compatibility with the MIPS R3000 processor. This soft-core processor can be used as IP for developing SOC (System on Chip). The soft-core processor was developed independently from companies which are related to the R3000 processor, so the developed processor do not include any design data and technical aid from these companies including the MIPS corporation. This paper introduces the details of the soft-core processor IP, and research and developments on on-chip multi-processors using this IP.
