1、指令中指定的动作决定了寄存器中的内容,Register has no types,assembly的操作数是寄存器 2、使用注释是个好习惯,没有多行注释,用#(hash)表示注释,并且它们不会被传递给处理器 3、寄存器使用x0~x31编号,x0是特殊的,始终存储0,因此其余31个寄存器可以保存变量值 RISC -V Add / Sub Instructions Comma:逗号 ...

1.1 汇编语言简介 汇编语言(Assembly Language)是一种“低级”语言,汇编语言一听就不高兴了:凭什么说我是低级语言,我哪里低级了。 其实此“低级”非彼“低级”,之所以说汇编语言是一种低级的语言,是因为其面向的是最底层的硬件,直接使用的是处理器的基本指令。因此,相对于抽象层次更高的C/C++语言,汇编语言确实是一...

This book explains the basics of code optimization, as well as how to interoperate with C and Python code, thus providing the starting points for your own projects as you develop a working knowledge of assembly language for various RISC-V processors. The RISC-V processor is the ne... (...
RISC-V assembly language includes two decision-making instructions, similar to an zf statement with ago to. The first instruction isbeq rsl, rs2, LIThis instruction means go to the statement labeled LI if the value in register rsl equals the value in register rs2. The mnemonic beq stands ...
(来源:Warren Gay - RISC-V Assembly Language Programming. Using ESP32-C3 and QEMU-Elektor International Media (2022)(Z-Lib.io)) esp32c3时钟频率 ESP32-C3 只支持 40MHz 晶振(精度为 ± 10 p p m ),匹配电容 C15 和 C17 的取值需要经过测试之后再行确定。
I was looking around for a board to tinker with RV32 assembly language as a way of getting to know the architecture a bit better. I tried using a WCH-Link debugger module and a CH32VF103 board but so far I have had no success using OpenOCD with it. I have opted instead to use ...
VMON is a tiny machine code monitor for RISC-V systems with UART communication written in RISC-V assembly language. Features hex and ASCII monitor disassembler with hex and decimal output currently disassembles RV32/64G instructions (some) pseudo instructions supported can be built for RV32 or ...
assembly 的时候生成 symbol table 和 relocation table: 以上的信息在链接的时候一起使用。 动态链接库和静态链接库 对于静态库而言,它是可执行文件的一部分,库更新了,运行中的程序需要重新编译。这是编译时链接的。 在Linux 下,提供了 .a 文件,用于处理,单个文件即使没有用到所有部分,也需要全部加载。 在动态...
