The OpenRISC 1200 processor is a widely used processor in small and medium embedded and networking application. It is open source and code of it is written in Verilog Hardware description language. It used Wishbone as an internal bus and also uses it to connect to external peripherals. Due ...

而现在才推出的RISC-V架构,则具备了后发优势,由于计算机体系结构经过多年的发展已经成为比较成熟的技术,多年来在不断成熟的过程中暴露的问题都已经被研究透彻,因此新的RISC-V架构能够加以规避,并且没有背负向后兼容的历史包袱,可以说是无病一身轻。 目前的“RISC-V架构文档”分为“指令集文档”(riscv-spec-v2....
