Claim One:
1. A pipelined apparatus for processing intra-frame video pixel block prediction comprising: a prediction module for predicting a pixel block based on boundary pixels of left and upper neighbor blocks of said pixel block; a DC pre-computation module for pre-computing a block of source DC-coefficients used with luma and chroma intra and inter prediction modes, based on said pixel block; a DC coefficients prediction module for predicting a block of predicted DC-coefficients, based on a reconstructed pixel block; a subtractor module for subtracting said predicted DC-coefficients from said source DC-coefficients to generate DC-coefficients of a prediction error; a forward transform module for forward transformation and quantization of said prediction error to generate a residual data; an inverse transform module for inverse transformation and quantization of said residual data; an adder module for adding said predicted pixel block to said inverse transformation and quantization of said residual data to generate said reconstructed pixel block; a mode selection and prediction pre-computation module to pre-compute mode selection of a best prediction mode of said luma and chroma intra and inter prediction modes, before said reconstructed block is generated; and an output module for outputting said residual data used in entropy or arithmetic coding, and said reconstructed pixel block; wherein all modules are hardware.
