问 我现在正用DSP55xx汇编编程，很多人都说容易，可给我感觉可真累，谁有好的编程方法与技巧，大家一起交流学习一下！
谢谢！
答 1: DSP55xx汇编编程是比6000的 答 2: 为什么不用c，然后再局部优化？而且55x还有流水线保护，多好 答 3: DSP55xx编程的一起来交流！1用汇编作实时处理比用c好得多，并且编实时算法时还要用汇编！
2用汇编可以更深刻理解DSP调用过程，硬件结构等而用C也只是编完并不明其理
！ 答 4: DSP55xx编程的一起来交流！看看下面这个例子：汇编也不是很难.即使不懂汇编也能看懂一些。
* Step 1: Section allocation
* −−−−−−
.def x,y,init
x .usect ”vars”,4 ; reserve 4 uninitalized 16-bit locations for x
y .usect ”vars”,1 ; reserve 1 uninitialized 16-bit location for y
.sect ”table” ; create initialized section ”table” to
init .int 1,2,3,4 ; contain initialization values for x
.text ; create code section (default is .text)
.def start ; define label to the start of the code
start
* Step 2: Processor mode initialization
* −−−−−−
BCLR C54CM ; set processor to ’55x native mode instead of
; ’54x compatibility mode (reset value)
BCLR AR0LC ; set AR0 register in linear mode
BCLR AR6LC ; set AR6 register in linear mode
* Step 3a: Copy initialization values to vector x using indirect addressing
* −−−−−−−
copy
AMOV #x, XAR0 ; XAR0 pointing to variable x
AMOV #init, XAR6 ; XAR6 pointing to initialization table
MOV *AR6+, *AR0+ ; copy starts from ”init” to ”x”
MOV *AR6+, *AR0+
MOV *AR6+, *AR0+
MOV *AR6, *AR0
* Step 3b: Add values of vector x elements using direct addressing
* −−−−−−−
add
AMOV #x, XDP ; XDP pointing to variable x
.dp x ; and the assembler is notified
MOV @x, AC0
ADD @(x+3), AC0
ADD @(x+1), AC0
ADD @(x+2), AC0
* Step 3c. Write the result to y using absolute addressing
* −−−−−−−
MOV AC0, *(#y)
end
NOP
B end
