Also instead of addq.l #1, use the (a0)+ and (a1)+more the 2 moves

You could use memcmp to compare the 2 buffers and only go in the "slow" comparison to display the error if memcmp fails. if(memcmp(buffer, read_buffer, BUFFER_SIZE) != 0) { for (int byte = 0; byte < BUFFER_SIZE; byte++) { if (read_buffer[byte] != (byte & 0xff)) { printf("Data mism...
