让我更详细地了解一些用于SISD的伪汇编代码（pseudo assembly code）。在这种情况下，我们要添加两个数组，每个数组包含两个元素。每个元素都是32位整数。一个从地址14开始，另一个从地址24开始：load r1，14load r2，24add r3，r1，r2; r3←r1 + r2load r1，18load r2，28add r4，r1，r2; r4←r1 + r2...
void vadd(int v1 [],int v2 [],int n,int v3 []){ int i = 0; while(i <n){ u = Vec3(v1 [i],v1 [i + 1],v1 [i + 3]); v = Vec3(v2 [i],v2 [i + 1],v2 [i + 3]); w = vadd3(u,v); //efficient vector operation v3 [i] = w.x0; v3 [i + 1] =...
Code generation: 做寄存器 allocation,代码生成 实际上,我们生成-S也需要指定编译选项,能指定-O。这里我们可以得到可靠的 RISC-V 的代码。它和我们的程序是逻辑上等价的,当然可能要进行一定的优化。 注意,在 RISC-V 中,编译是会产生便于理解的伪指令的。 汇编 将汇编语言生成 ELF 的 object file, object file ...
RISC-V是一个64位的中央处理器,xv6是用基于“LP64”的C语言编写的,这意味着C语言中的long(L)和指针(P)变量都是64位的,但int是32位的。 这本书假设读者已经在一些架构上做了一些机器级编程,并将在出现时介绍RISC-V特定的想法。 RISC-V的一个有用的参考文献是《The RISC-V Reader: An Open Architecture...
This Visual Studio Code extension embeds the popularVenus RISC-V simulator. It provides a standalone learning environment as no other tools are needed. It runs RISC-V assembly code with the standard debugging capabilities of VS Code. To use it as educational tool, further views are added as ...

a C compiler is to machine language or assembly code. There are other challengers to the throne such as SpinalHDL which have small but enthusiastic followings. [Tom] has a post about how theVexRISC-V CPU leverages SpinalHDLto make an extremely flexible system that is as efficient as plain Ve...
