Explanation
When accessing the M_AXI arrays, maintaining a sequential and continuous access pattern is critical or burst inferencing can fail. Ensure that the code accesses the array sequentially and in the same order.
Example
//////////// ORIGINAL ////////////
void foo(int *a, int *b) {
for (long i = 0; i < 256; ++i)
b[i*4] = a[i*4] ;
}
//////////// UPDATED ////////////
// Use continuous accesses
void foo(int *a, int *b) {
for (long i = 0; i < 256; ++i)
b[i] = a[i] ;
}
