AX60 系列的第一个成员-- AX65支持RISC-V最新的指令集扩展,例如纯量加密(scalar cryptography)扩展指令集和位操作 (bit manipulation)扩展指令集。AX65核心是一个具有13级流水线,4路 (4-way)超纯量,乱序 (Out-of-Order )执行的处理器。在TAGE (TAgged GEometric history length)高准确率循环动态分支预测器的...
最近几年RISC-V的大火,让IC行业开始关注RISC-V这个迅猛发展的架构,但提到这个年轻的架构,大家最先想到的是,薄弱的生态,硬件的碎片化。RISC-V从发展之初就旨在提供高度模块化和可拓展的指令集,用户甚至可以自己拓展指令集,这种灵活性有利于特定方向的芯片优化。但随之而来的问题就是各个厂商对于拓展的支持各不相同,甚...
RISC-V Linux 6.3 changelog BPF trampolines are now fully supported on (s390x and)RISC-VRV64 systems. RISC-V kernels can use the “ZBB” bit-manipulation extension, when present, to accelerate string operations. Various improvements to the extension detection and alternative patching infrastruc...
