RISC-V 芯片架构新规范
2022-06-26 13:13:00 【ejinxian】
RISC-V International 规范和扩展的(40 多个扩展的 16 个规范获得了批准)
RISC-V Efficient Trace (E-Trace)、
RISC-V Supervisor 二进制接口 (SBI)、
RISC-V 统一可扩展固件接口 (UEFI) 规范,
RISC-V Zmmul multiply-only 扩展。

RISC-V 新规范加速了嵌入式和大型系统设计。“调试是芯片上最难做的事情之一,用于 RISC-V 的 E-Trace 创建了一种一种标准的处理器跟踪方式,非常高效且在嵌入式系统设计中特别有用。RISC-V SBI 为开发人员提供了同样重要的资源。在所有 RISC-V 实现中移植 supervisor-mode 软件的能力,基本上允许开发人员编写一次代码就能在任何地方应用
