APPARATUS AND METHOD FOR SLIDING WINDOW DATA GATHER

摘要

An apparatus and method are described for fetching and storing a plurality of portions of a data stream into a plurality of registers. For example, a method according to one embodiment includes the following operations: determining a set of N vector registers into which to read N designated portions of a data stream stored in system memory; determining the system memory addresses for each of the N designated portions of the data stream; fetching the N designated portions of the data stream from the system memory at the system memory addresses; and storing the N designated portions of the data stream into the N vector registers.

1. A processor to execute an instruction to perform the operations of:
determining a set of N vector registers into which to read N designated portions of a data stream stored in system memory starting at a memory location i=0, j=0, and k=0; determining the system memory addresses for each of the N designated portions of the data stream; fetching the N designated portions of the data stream from the system memory at the system memory addresses; storing the N designated portions of the data stream into the N vector registers; and iterating the above operations for all memory locations from i=1 to X, j=0 to Y, and k=0 to Z, where X, Y and Z are positive integers.
