Hi,
I am debug a filter program. This code originates from a DSP application book. It uses circular addressing in assembly lanuage, with a separate filter coefficient file bp1750.cof. This file fits our requirement. The strange thing is that the coefficients are changed after restart for a second time debug. If I reload the program in CCS Debug, the problem is the same with that of restart. I don't think it is normal way.
I add the relavant code here. The C header is:
#include <stdio.h>
#include "bp1750.cof"
The bp1750.cof is:
#define N 128 /*length of filter*/
short h[N]=
{
-1,2,8,-1,-19,-7,
28,24,-27,-41,14,47,
4,-34,-12,7,-8,15,
55,-8,-113,-41,146,119,
-129,-186,61,197,17,-134,
-44,26,-28,54,192,-28,
-377,-134,475,381,-409,-586,
191,617,54,-419,-137,82,
-89,175,629,-95,-1296,-478,
1762,1488,-1702,-2646,955,3526,
368,-3751,-1901,3161,3161,-1901,
-3751,368,3526,955,-2646,-1702,
1488,1762,-478,-1296,-95,629,
175,-89,82,-137,-419,54,
617,191,-586,-409,381,475,
-134,-377,-28,192,54,-28,
26,-44,-134,17,197,61,
-186,-129,119,146,-41,-113,
-8,55,15,-8,7,-12,
-34,4,47,14,-41,-27,
24,28,-7,-19,-1,8,
2,-1
};
...............
Is there a way to avoid filter coefficients changed without leaving the CCS Debug and re-enter?
Thanks.
