backpressure at jpeg_output.v

assign inport_accept_o = (y_level_w <= 32'd384 && cr_level_w <= 32'd128) | idle_o;
For 4:2:0 ratio jpeg image, the cr_level_w increases 4 at a time, which means for a block with 64 elements, cr_level_w<=128 could only hold half a block before raise back pressure, is it intended ?
