There needs to be at least a ping-pong (2 deep) buffer in SL2 for temporal predictor fetch. This fetch is only needed while processing the base layer of the pyramid. This fetch needs to be disabled for other layer processing. Since a paxel level predictor evaluation is performed, only alternate (even) lines needs to be fetched for this buffer from the external memory. The UTC source side fetch parameters need to be programmed appropriately. Every line of this buffer needs to start from a new SL2 word. There cannot be any overlap with the previous word.
