1、.DSP实验报告定点小数乘法实验目的1、 自行安装CCS3.3版本，配置和运行CCS;2、 熟悉CCS开发环境，访问读写DSP寄存器AC0-AC3，AR0-AR7，T0-T3;3、 结合c5510的存储器空间分配，访问DSP的内部RAM;4、 编写一个简单的定点DSP程序，计算一个式子。实验结果CCS安装运行后如下：初始界面选择C5510simulator建立新工程；建立新汇编语言源程序文件；建立CMD文件；访问读写寄存器AC0-AC3，AR0-AR7，PC,T0-T3:计算一个简单乘加算式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运行后寄存器的结果如下：计算得结果应为724.12，但由于修改小数点的位置使计算结果有些偏差。CMD文件如下：-e start-stack 500-sysstack 500MEMORY MMR: o = 0x000000 l = 0x0000c0 /*
