memory replication

I'm confused about when and why the compiler replicates memory. I have a kernel that reads in a block of data and fills up a 2D memory array. THe read process is done serially through a channel. ...

what is your struct of msg_t?

compiler will auto banking at lowest dimension.

your lowest dimension is msg_t.

maybe you can try use another struct

typedef struct{

msg_t kk[512];

} msg_ch;

local msg_ch msgMem[180];

for(uint k=0; k<NLDPC/M; k++)

{

# pragma unroll 1

for(uint r=0; r<M; r++){

msgMem[k].kk[r] = read_channel_intel(LDPC_DEC_SDATA_OUT);

}

}

msg = msgMem[jOffset];
