Abstract: Method, apparatus, and program means for performing bitstream buffer manipulation with a SIMD merge instruction. The method of one embodiment comprises determining whether any unprocessed data bits for a partial variable length symbol exist in a first data block is made. A shift merge operation is performed to merge the unprocessed data bits from the first data block with a second data block. A merged data block is formed. A merged variable length symbol comprised of the unprocessed data bits and a plurality of data bits from the second data block is extracted from the merged data block.

Abstract: Method, apparatus, and program means for shuffling data. The method of one embodiment comprises receiving a first operand having a set of L data elements and a second operand having a set of L control elements. For each control element, data from a first operand data element designated by the individual control element is shuffled to an associated resultant data element position if its flush to zero field is not set and a zero is placed into the associated resultant data element position if its flush to zero field is not set.

Abstract: In accordance with embodiments disclosed herein, there are provided methods, systems, mechanisms, techniques, and apparatuses for implementing optional logging of debug activities in a real time instruction tracing log. For example, in one embodiment, such means may include an integrated circuit having means for initiating instruction tracing for instructions of a traced application, mode, or code region, as the instructions are executed by the integrated circuit; means for generating a plurality of packets to a debug log describing the instruction tracing; means for initiating an alternative mode of execution within the integrated circuit; and means for suppressing indication of entering the alternative mode of execution. Additional and alternative means may be implemented for selectively causing an integrated circuit to operate in accordance with an invisible trace mode or a visible trace mode upon transition to the alternative mode of execution.

Abstract: An apparatus and method are described for real time instruction tracing. For example, a method according to one embodiment comprises: recording user specified address ranges for which tracing is required; monitoring a next linear instruction pointer (NLIP) values and/or branch linear instruction pointer (BLIP) values to determine if address range has been entered; when the range is entered, compressing the NLIP and/or BLIP values and constructing fixed length packets containing the tracing data; and transferring the fixed length packets to a memory execution cluster.

Abstract: Method, apparatus, and program means for nonlinear filtering and deblocking applications utilizing SIMD sign and absolute value operations. The method of one embodiment comprises receiving first data for a first block and second data for a second block. The first data and said second data are comprised of a plurality of rows and columns of pixel data. A block boundary between the first block and the second block is characterized. A correction factor for a deblocking algorithm is calculated with a first instruction for a sign operation that multiplies and with a second instruction for an absolute value operation. Data for pixels located along said block boundary between the first and second block are corrected.
