Patent ID: 7301542

Claim:
A circuit for decompressing and filtering oversampled data, the circuit comprising: a latency buffer configured to accept oversampled data from a frame buffer; a memory configured to store a plurality of compression bits indicating which sections of the oversampled data in the frame buffer are compressed; a decompression unit configured to receive the oversampled data from the latency buffer and the compression bits from the memory and further configured to decompress a first section of the oversampled data during a scanout operation in the event that one of the compression bits indicates that the first section of the oversampled data is compressed, wherein the compressed first section of the oversampled data includes one or more color values; and a filter configured to compute a pixel value from a plurality of sample values provided by the decompression unit, the sample values including at least a portion of the decompressed data, and to transmit the pixel value for displaying by a display device, wherein the filter computes the pixel value during a scanout operation.
