Techniques related to parallel block video coding using an adaptive wavefront split are discussed. Such techniques include adaptively applying a wavefront split in a video frame based on a frame level quantization parameter of the video frame, an encode duration of a previous frame, and/or image content of the video frame.

A method and apparatus for including in processor instructions for performing logical-comparison and branch support operations on packed or unpacked data. In one embodiment, instruction decode logic decodes instructions for an execution unit to operate on packed data elements including logical comparisons. A register file including 128-bit packed data registers stores packed single-precision floating point (SPFP) and packed integer data elements. The logical comparisons may include comparison of SPFP data elements and comparison of integer data elements and setting at least one bit to indicate the results. Based on these comparisons, branch support actions are taken. Such branch support actions may include setting the at least one bit, which in turn may be utilized by a branching unit in response to a branch instruction. Alternatively, the branch support actions may include branching to an indicated target code location.

According to a first aspect, efficient data transfer operations can be achieved by: decoding by a processor device, a single instruction specifying a transfer operation for a plurality of data elements between a first storage location and a second storage location; issuing the single instruction for execution by an execution unit in the processor; detecting an occurrence of an exception during execution of the single instruction; and in response to the exception, delivering pending traps or interrupts to an exception handler prior to delivering the exception.

In one embodiment, the present invention includes logic to receive a permute instruction, first and second source operands, and control values, and to perform a permute operation based on an operation between at least two of the control values so that selected portions of the first and second source operands or a predetermined value can be stored into elements of a destination. Multiple permute instructions may be combined to perform efficient table lookups. Other embodiments are described and claimed.
