International Classification:

H04L 700

US Classification:

375354

Abstract:

An apparatus and method for receiving time skewed data from a parallel data bus. A data transfer on the parallel data bus is preceded by a start-of-cell delimiter consisting of a predetermined sequence of pulses on each of the data signals. The data is received from the bus by receive logic employing a local clock. Sampling logic is used to sample each of the data signals received from the bus at a rate which is higher than the local clock rate. Sample registers store a plurality of samples of corresponding data signals, the number of samples stored being large enough to store at least some of the pulses constituting the start-of-cell delimiter. Start-of-cell detect and center select logic is used for determining that a start-of-cell delimiter is stored in each of the sample registers, and for determining which of the samples stored in each of the sample registers represents the approximate center sample of one of the pulses of the start-of-cell delimiter. These center samples correspond to the data signals on the bus, but are de-skewed and synchronous with the local clock.

Abstract:

Various apparatuses and methods are disclosed for processing texture data compressed with a first compression algorithm and texture data compressed with a second compression algorithm. A processing system may be used to determine whether the compressed texture data is compressed with the first or second compression algorithm, and process the compressed texture data using a decompression algorithm corresponding to the compression algorithm used to compress the texture date.
