Abstract: A prediction processing system includes a processing circuit and a reference data buffer. The processing circuit performs a first inter prediction operation upon a first prediction block in a frame to generate a first inter prediction result, and further performs a second inter prediction operation upon a second prediction block during a first period. The reference data buffer buffers a reference data derived from the first inter prediction result. The processing circuit further fetches the reference data from the reference data buffer, and performs a non-inter prediction operation according to at least the reference data during a second period, wherein the second period overlaps the first period.
