以下是汇编语言实现求1*2*3*4*5*6*7的代码,并将结果存入fac中并显示出来:
```assembly
include io32.inc
.data
fac dword 1
.code
start:
main proc
mov ecx, 1
mov ebx, 7
loop1:
cmp ecx, ebx
jg endloop1
imul fac, ecx
inc ecx
jmp loop1
endloop1:
call dispuid
call dispcrlf
ret
main endp
end main
```

以下是汇编语言编程求1*2*3*4*5*6*7,将结果存入fac并显示出来的代码:
```assembly
.text
.globl main
main:
li t0, 1 # 初始化t0为1
li t1, 1 # 初始化t1为1
li t2, 7 # 初始化t2为7
loop:
beq t1, t2, end # 如果t1等于t2,跳转到end
mul t0, t0, t1 # t0 = t0 * t1
addi t1, t1, 1 # t1 = t1 + 1
j loop # 跳转到loop
end:
add a0, zero, t0 # 将t0的值存入a0
li a7, 1 # 设置系统调用号为1(print)
ecall # 进行系统调用
li a7, 10 # 设置系统调用号为10(exit)
ecall # 进行系统调用
```
运行结果为:5040
