If cyclic prefix insertion is used, more samples are unloaded from the core than are loaded. Therefore, the core cannot continuously stream frames, but must insert a gap of cyclic prefix length clock cycles in between each frame of input data to accommodate the additional clock cycles required to unload the cyclic prefix ( This Figure ). This is indicated by the TREADY signal on the Data Input channel. This goes Low to allow the core time to unload the cyclic prefix.
