A processor includes a decode unit to decode a packed data alignment plus compute instruction. The instruction is to indicate a first set of one or more source packed data operands that is to include first data elements, a second set of one or more source packed data operands that is to include second data elements, at least one data element offset. An execution unit, in response to the instruction, is to store a result packed data operand that is to include result data elements that each have a value of an operation performed with a pair of a data element of the first set of source packed data operands and a data element of the second set of source packed data operands. The execution unit is to apply the at least one data element offset to at least a corresponding one of the first and second sets of source packed data operands. The at least one data element offset is to counteract any lack of correspondence between the data elements of each pair in the first and second sets of source packed data operands.

Packed data alignment plus compute instructions, processors, methods, and systems

A processor includes a decode unit to decode a packed finite impulse response (FIR) filter instruction that indicates one or more source packed data operands, a plurality of FIR filter coefficients, and a destination storage location. The source operand(s) include a first number of data elements and a second number of additional data elements. The second number is one less than a number of FIR filter taps. An execution unit, in response to the packed FIR filter instruction being decoded, is to store a result packed data operand. The result packed data operand includes the first number of FIR filtered data elements that each is to be based on a combination of products of the plurality of FIR filter coefficients and a different corresponding set of data elements from the one or more source packed data operands, which is equal in number to the number of FIR filter taps.
