I’m new to PYNQ board, but my goal is very straightforward: do a matrix multiplication using the pynq board.

I have an IP created using HLS that looks like the following:

```
void matrixmul(
mat_a_t a[MAT_A_ROWS][MAT_A_COLS],
mat_b_t b[MAT_B_ROWS][MAT_B_COLS],
result_t res[MAT_A_ROWS][MAT_B_COLS])
{
#pragma HLS ARRAY_RESHAPE variable=b complete dim=1
#pragma HLS ARRAY_RESHAPE variable=a complete dim=2
#pragma HLS INTERFACE ap_fifo port=a
#pragma HLS INTERFACE ap_fifo port=b
#pragma HLS INTERFACE ap_fifo port=res
mat_a_t a_row[MAT_A_ROWS];
mat_b_t b_copy[MAT_B_ROWS][MAT_B_COLS];
int tmp = 0;
// Iterate over the rowa of the A matrix
Row: for(int i = 0; i < MAT_A_ROWS; i++) {
// Iterate over the columns of the B matrix
Col: for(int j = 0; j < MAT_B_COLS; j++) {
#pragma HLS PIPELINE rewind
// Do the inner product of a row of A and col of B
tmp=0;
// Cache each row (so it's only read once per function)
if (j == 0)
Cache_Row: for(int k = 0; k < MAT_A_ROWS; k++)
a_row[k] = a[i][k];
// Cache all cols (so they are only read once per function)
if (i == 0)
Cache_Col: for(int k = 0; k < MAT_B_ROWS; k++)
b_copy[k][j] = b[k][j];
Product: for(int k = 0; k < MAT_B_ROWS; k++) {
tmp += a_row[k] * b_copy[k][j];
}
res[i][j] = tmp;
}
```

}

}

And I import the design into Vivado, which that looks like this:

My question is, how do I go about connecting these 2 components? Any help would be appreciated, thank you.
