A method and system for low-latency processing of intra-frame video pixel block prediction including: predicting a pixel block based on boundary pixels of left and upper neighbor blocks of said pixel block; subtracting said predicted pixel block from a source pixel block to generate a prediction error; forward transforming and quantizing said prediction error to generate a residual data; inverse transforming and quantizing said residual data; adding said predicted pixel block to said inverse transformed and quantized residual data to generate a reconstructed pixel block; pre-computing blocks of DC-coefficients used with luma and chroma intra prediction modes; pre-computing mode selection of a best prediction mode of said luma and chroma intra prediction modes; and outputting said residual data to be used in entropy or arithmetic coding, and a reconstructed data used for motion prediction.

System and method for low-latency processing of intra-frame video pixel block prediction

A parallel processor for motion estimation including: a matrix of elementary processors configured in rows and columns, local connections between the elementary processors for transmitting partial results, and row outputs for outputting a set of best match values (for example, SAD values), one value for each pixel row of a current block of image pixels; and search area delay buffers coupled to each row inputs, for accepting pixels of the search area as input and forming a reference block row. The processor further includes current block delay buffers coupled to each row inputs, for accepting pixels of the current block as input; a sum module coupled to the row outputs for computing a final match value from the row outputs; and a sorting module for sequentially selecting a best match value from the final match values outputted from the sum module, and generating a corresponding motion vector.
