利用C语言调用汇编子程序

其中5个输入参数和3个返回结果的汇编子程序调用

a) 输入整数a,b,c,d,e,

b) 请计算a+b+c,a+c+d+e,a-b的值

c) 讨论a-b后算术状态标志寄存器的状态 (ASTAT)

d) 请讨论输入整数数组e[3],f[3]，参数如何传递的



本实验要求在Visual DSP++ ADSP-BF535 Blackfin环境中编写一个简单的程序：C语言的主程序调用汇编语言的函数，完成简单的加法、减法。实验重点在于掌握汇编程序的调用方法，以及参数的传递，寄存器的数据存放。-Using C language to call the assembly routines which five input parameters and return results compiled three subroutine calls a) input integers a, b, c, d, e, b), calculate a+ b+ c, a+ c+ d+ e, ab value of c) discuss the ab after the arithmetic status flags register state (ASTAT) d) Please discuss the input integer array e [3], f [3], parameters to pass the test required in Visual DSP++ ADSP- BF535 Blackfin environment, write a simple program: C language, assembly language function called main program to complete simple addition and subtraction. Experiment focused on master assembler call methods and pass parameters, register the data store.
