A cross-platform GUI tool for converting between Assembly and Machine Code (Hex), powered by Keystone Engine and Capstone Engine. [v2-asm2hex2](https://github.com/suifei/asm2hex2) > 新版本使用C ++(cpp)重构,而原始版本是使用Golang开发的。一个跨平台的GUI工具,用于在Assembly和机器代码(Hex)...
每当指令试图执行非法操作时,RISC-V CPU都会生成异常,例如执行CPU无法识别的指令。 包含机器和用户/应用程序模式的RISC-V系统通常包括一个内存保护单元,当CPU试图读写数据或从特定地址获取执行指令时,可以配置该单元以生成异常。操作系统可以通过将此单元配置为在用户/应用程序模式下执行的代码试图访问受保护的地址时生成...
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 ...

本文主要分析RISCV linux kernel的启动汇编部分代码。先结合链接脚本和汇编代码介绍镜像头和启动汇编代码部分的执行过程。后面文章再详细分析重定向,mmu设置等相关重点内容。 代码路径arch/riscv/kernel/head.S,不同版本内核可能有点差异。 二.根据链接脚本查找入口与镜像头介绍 ...
to generate machine language code. In this article, ASPIRE is introduced, selected features of the simulator that interactively explain the RISC-V ISA as teaching aides are presented, then two assembly algorithms are evaluated. Both assembly algorithms run in real time as code is being edited in...
