本Review为之前周课的补充，在阅读本Review之外，建议阅读其他周课课件。底部附aid sheet一份浮点的表示(Floating Point) 浮点，即某小数在二进制里的表示。需注意大部分情况下，浮点存储的数据都只是对真实数字的一个approximation，譬如1/3这个无限小数是不可能用浮点准确表达的。浮点十进制与二进制的转换(IEEE754标准) 等下补充，不想学就用计算器算：https://www.h-schmidt.net/FloatConverter/IEEE754.html 写码技巧程序结束如无特殊说明，任何程序结束时都需放入一个无限循环 END: MOV PC, END（不建议，理由见“三种方法将某地址放入某register”。假如这是个很大的程序，这一行码会在地址257出现，即END代表257这个地址，compile时会发生什么？） END: B END (简单易用) (Q: 不然会发生什么？A: “Instruction fetched from a location outside of a code section (.text or .exceptions).”每个程序都由不同的segment组成。在每一个可执行程序ELF里，都有header说明各segment开始和结束的地址。当一个非.text的地址进入了PC，debugger就会报以上错。各segment的定义 ) 三种方法将某个地址放入某register MOV R0, #0x10 (不建议)墙裂不建议使用MOV指令对大于一个byte Read more…
