local memory bank

I have also modified the code, but the RAM blocks usage become even worse larger than 64.

typedef struct{
    short ff;
} filter_trans;
typedef struct{
    filter_trans ww;
} data_trans;
typedef struct{
    filter_trans ww;
} weight_trans;
__kernel(){
      short __attribute__((numbanks(16),bankwidth(2))) w_local;
      data_trans data_in = read_channel_intel(data_ch);
      cont control = read_channel_intel(cont_ch);
      weight_trans get_w;
     # pragma unroll      
       for(int n=0; n<4; n++){
           # pragma unroll
            for(int j=0; j<16; j++){
                get.ww.ff = w_local;
            }
      }
      
     # pragma unroll      
       for(int n=0; n<4; n++){
            winograd = 0;
           # pragma unroll
            for(int j=0; j<16; j++){
                winograd += get_w.ww.ff * data_in.ww.ff;
            }
      }
}

Private memory Optimal

Total replication 1

Number of banks 16 (banked on lowest dimension)

Bank depth 16384 words

Additional information

Requested size 294912 bytes, implemented size 524288 bytes, stall-free, 16 reads and 16 writes.

Banked on lowest dimension into 16 separate banks.

Reducing accesses to exactly one read and one write for all on-chip memory systems may increase overall system performance.
