Abstract
A system and method for performing sample rate conversion by an execution unit, including receiving an instruction, where the instruction comprises an irregular shifting pattern of data elements stored in a vector register, and shifting the data elements in the vector register according to the irregular shifting pattern. In case of upsampling the irregular shifting pattern includes an indication stating whether a memory element loads a data element from an immediate next memory element or from a second next memory element. In case of downsampling the irregular shifting pattern includes an indication stating whether a memory element in the input vector register loads a data element from an immediate next memory element, or whether the memory element loads a data element previously stored in a shadow vector register and the data element stored in the immediate next memory element is loaded into the shadow vector register.
