文檔簡介

1、.DSP實驗報告定點小數(shù)乘法實驗目的1、 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、 結合c5510的存儲器空間分配，訪問DSP的內部RAM;4、 編寫一個簡單的定點DSP程序，計算一個式子。實驗結果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 #0006h,AC0H;Q6

2、 MOV #0026h,AC1H;Q5 MPY AC1,AC0 MOV #0023h,AC1H;Q0 MOV #0014h,AC2H;Q0 MPY AC2,AC1 MOV #03C0h,AC2H;Q6 MOV #0033h,AC3H;Q5 MPY AC3,AC2 SFTSC AC1,#11,AC3 ADD AC0,AC3 ADD AC2,AC3運行后寄存器的結果如下：計算得結果應為724.12，但由于修改小數(shù)點的位置使計算結果有些偏差。CMD文件如下：-e start-stack 500-sysstack 500MEMORY MMR: o = 0x000000 l = 0x0000c0 /*
