RISC3202: A Software Configuration Dual-Issue/Dual-Core Microprocessor

摘要

RISC-based processors have been extended into almost all kinds of embedded applications. These applications have different features thus require different processor architectures. Thus, we have developed a dual-core/dual-issue mixed microarchitecture processor named as RISC3202 which is based on two simple RISC cores. On the one hand, RISC3202 is an in-order dual-issue superscalar processor for single-thread applications. On the other hand, RISC3202 is a shared-memory dual-core processor for multiple-thread applications. The work mode of RISC3202 is configurable during running programs. Therefore, RISC3202 fits well for different features of target applications and its hardware usage rate is always high.
