Abstract
Based on 32 bit single-issue processor RISC3201, a multi-mode processor RISC3203 was designed to satisfy requirements of different embedded applications. RISC3203 could operate with three modes: dual-issue mode, dual-core mode and dual-thread mode. During the design, the IP reuse methodology was adopted into mixing the micro-architecture of multiple modes. The thread switch with low cost was implemented. Comparing with RISC3201, the performance of RISC3203 improved 70~80%, while the gate cost of pipeline increased 105%.
