實(shí)驗(yàn)一ARM匯編指令

1.實(shí)驗(yàn)?zāi)康?/p>

(1)初步學(xué)會(huì)使用ADS1.2集成開(kāi)發(fā)環(huán)境及ARM軟件模擬器；

(2)通過(guò)實(shí)驗(yàn)掌握簡(jiǎn)單ARM匯編指令的使用

2.實(shí)驗(yàn)設(shè)備

(1)硬件：PC機(jī)

(2)軟件：ADS1.2集成開(kāi)發(fā)環(huán)境，Windows98/2000/NT/XP

3.實(shí)驗(yàn)內(nèi)容

(1)熟悉ADS開(kāi)發(fā)環(huán)境，并使用LDR/STR和MOV等指令訪問(wèn)寄存器或

存儲(chǔ)單元；

(2)使用ADD/SUB/LSL/LSR/AND/ORR/等指令完成基本數(shù)學(xué)邏輯運(yùn)算。

1)實(shí)驗(yàn)A——完成運(yùn)算x+y,把結(jié)果存入堆棧寄存器(R13)中

在該實(shí)驗(yàn)中主要是通過(guò)MOV/STR/LDR/ADD等指令來(lái)完成基本的加操作運(yùn)

算。

2)實(shí)驗(yàn)A運(yùn)行截圖
