I an using cfft_fr16(),when application is running
error happened:
data access misaligned address violation
- Attempted misaligned data memory or data cache access
when I used command bfin-uclinux-addr2line to trace the
problem. the result is:
.start_s_butterfly
cfft_fr16.asm:0
the programe is follow:
#define SIZE 512
complex_fract16 twiddle_table[SIZE];
complex_fract16 input[SIZE];
complex_fract16 output[SIZE];
int main(int argc, char* argv[]) {
int p;
twidfftrad2_fr16(twiddle_table, SIZE);
cfft_fr16(input, output, twiddle_table, 1, SIZE,
&p,0);
}
How to solve this preblem????
thanks
