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.

A video processing apparatus implemented in a chip includes an on-chip prediction buffer and a processing circuit. The on-chip prediction buffer is shared by a plurality of coding tools for prediction, and is used to store reference data. The processing circuit supports the coding tools for prediction, reads a plurality of first reference data from the on-chip prediction buffer as input data of a first coding tool that is included in the coding tools and enabled by the processing circuit, and writes output data of the first coding tool enabled by the processing circuit into the on-chip prediction buffer as a plurality of second reference data.

A video processing apparatus includes a reconstruct circuit, a storage device, and an intra prediction circuit. The reconstruct circuit generates reconstructed pixels of a first block of a picture. The storage device at least stores a portion of the reconstructed pixels of the first block, wherein a capacity of the storage device is smaller than a reconstructed data size of the picture. The intra prediction circuit performs intra prediction of a second block of the picture based at least partly on pixel data obtained from the storage device.

One exemplary video processing apparatus includes a control circuit and a size selection circuit. The control circuit determines picture boundary information. The size selection circuit refers to at least the picture boundary information to select a size for a block associated with encoding of a picture, wherein selection of the size is constrained by the picture boundary information to ensure that the block with the selected size is not across a picture boundary of the picture.
