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 subtracter module for subtracting said predicted pixel block from a source macroblock to generate 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 a reconstructed pixel block; a pre-computation module for pre-computing a block of DC-coefficients used with luma and chroma intra prediction modes; a mode selection and prediction pre-computation module for pre-computing mode selection of a best prediction mode of said luma and chroma intra prediction modes; and an output module for outputting said residual data used in entropy or arithmetic coding, and said reconstructed pixel block.
