## 51单片机（8051）的汇编方法：
（1）生成二进制的方法：用Keil C51 uvision2（或者keil 4），A51和L51，待考；或者用as31和sdcc（在www.pjrc.com/tech/8051），方法是as31 -l -Fbin test.asm。或者sdas8051 -l test.asm（需要改成0x表示十六进制常量，但输出二进制可能不正确）。asx8051似乎编译失败
（2）示例代码：stc-isp有IO的汇编示例（不过太长了）；或者找《8051 单片机P1口实验》MOV P1；或者找这个《Blinking LED using 8051》用CPL P1.0取反（只支持P1的位取反，似乎不支持整个P1字节取反）：www.circuitstoday.com/blinking-led-using-8051

## 6502的汇编方法：
（1）生成二进制的方法：用cc65，方法是ca65 test.asm和ld65 -t none test.o（如果需要列表文件，可能要da65反汇编或者在ca65中生成，但可能缺少跳转地址）。或者用dasm，可能会在头部两字节添加偏移，需要自己去掉，或者生成list文件。注意cc65和dasm的伪指令可能不兼容
（2）示例代码：参考www.instructables.com/6502-6522-Minimal-Computer-With-Arduino-MEGA和它的前篇（可以把jmp后面的常量改成标号）。或者参考free6502的测试汇编
* 6502 & 6522 Minimal Computer (with Arduino MEGA) Part 2
* program1
```
LDA#$55
NOP
ROL
STA$1010
JMP$1000
The ROL rotates the contents of the accumulator one bit left which means the $55 now becomes $AA.
In machine code (hex): A9 55 EA 2A 8D 10 10 4C 00 10
```
* program2
```
LDA#$01
STA$8100

STA$8100
JMP$1005
In machine code (hex): A9 01 8D 00 81 69 03 8D 00 81 4C 05 10
```
## TD4的汇编方法：
（1）生成二进制的方法：在网页上vanya.jp.net/td4/，只支持单指令汇编。另一个命令行版本：wuxx/TD4-4BIT-CPU/software/td4as.exe。
（2）示例代码：（TD-4GP02A）vanya.jp.net/td4/，或者参考wuxx/TD4-4BIT-CPU/software/test/test_0_output.s
## arm gdb arm-linux-run and qemu-arm
* see mips and arm asm samples in gdb source
* 以前提到过，如果源码编译arm目标的gdb代码，会生成一个arm-linux-run工具（具体运行的汇编示例参考gdb源码），所以gdb代码也有汇编例子。其实qemu也有一个类似的，叫用户模式qemu，就是除了qemu-system-arm，还有一个叫qemu-arm的命令，可以运行arm-linux-gnueabi-gcc -static静态生成的elf文件。原理大概是拦截最底层的控制台输出，arm的话不清楚，但mips是有专门的syscall指令用于控制台输出
