#pragma HLS INTERFACE s_axilite defines one s_axilite interface, which specifies an AXI4-Lite slave I/O protocol with bundle=control fo all arguments (size and iterCnt) and return.
#pragma HLS INTERFACE axis defnes one axis interface (specifying an AXI4-Stream I/O protocol).
#pragma HLS PIPELINE II=1 pipelines a for loop that is a candidate for burst read because the memory addresses per loop iteration are consecutive (ARBURST=INCR). To pipeline this for loop, set the initiation interval (II) = 1.
