Instructions and logic provide SIMD vector population count functionality. Some embodiments store in each data field of a portion of n data fields of a vector register or memory vector, at least two bits of data. In a processor, a SIMD instruction for a vector population count is executed, such that for that portion of the n data fields in the vector register or memory vector, the occurrences of binary values equal to each of a first one or more predetermined binary values, are counted and the counted occurrences are stored, in a portion of a destination register corresponding to the portion of the n data fields in the vector register or memory vector, as a first one or more counts corresponding to the first one or more predetermined binary values.

Methods, apparatus, instructions and logic to provide population count functionality for genome sequencing and alignment

An application accelerator (AA) unit that in one embodiment is part of an I/O processor (IOP) integrated circuit. The AAU includes logic circuitry for improving the performance of storage applications such as Redundant Array of Inexpensive Disks (RAID). A boolean unit performs operations such as exclusive-or (XOR) on multiple blocks of data to form the image parity block which is written to the redundant disk array. The AAU is associated with a memory-mapped programming interface that allows software executed by a core processor in the IOP to utilize the AAU for accelerating RAID storage applications as well as local memory DMA-type transfers, using the descriptor construct.
