西工大DSP定點小數(shù)乘法

1、精選優(yōu)質(zhì)文檔-傾情為你奉上DSP實驗報告定點小數(shù)乘法實驗?zāi)康?、 自行安裝CCS3.3版本，配置和運行CCS;2、 熟悉CCS開發(fā)環(huán)境，訪問讀寫DSP寄存器AC0-AC3，AR0-AR7，T0-T3;3、 結(jié)合c5510的存儲器空間分配，訪問DSP的內(nèi)部RAM;4、 編寫一個簡單的定點DSP程序，計算一個式子。實驗結(jié)果CCS安裝運行后如下：初始界面選擇C5510simulator建立新工程；建立新匯編語言源程序文件；建立CMD文件；訪問讀寫寄存器AC0-AC3，AR0-AR7，PC,T0-T3:計算一個簡單乘加算式ASM源程序如下：.text.global startstart: MOV #0
