Abstract: 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.

Abstract: Embodiments of an invention a processor architecture are disclosed. In an embodiment, a processor includes a decoder, an execution unit, a coherent cache, and an interconnect. The decoder is to decode an instruction to zero a cache line. The execution unit is to issue a write command to initiate a cache line sized write of zeros. The coherent cache is to receive the write command, to determine whether there is a hit in the coherent cache and whether a cache coherency protocol state of the hit cache line is a modified state or an exclusive state, to configure a cache line to indicate all zeros, and to issue the write command toward the interconnect. The interconnect is to, responsive to receipt of the write command, issue a snoop to each of a plurality of other coherent caches for which it must be determined if there is a hit.

Abstract: A processor includes a decode unit to decode an instruction that is to indicate a first source packed data operand that is to include at least four data elements, to indicate a second source packed data operand that is to include at least four data elements, and to indicate one or more destination storage locations. The execution unit, in response to the instruction, is to store at least one result mask operand in the destination storage location(s). The at least one result mask operand is to include a different mask element for each corresponding data element in one of the first and second source packed data operands in a same relative position. Each mask element is to indicate whether the corresponding data element in said one of the source packed data operands equals any of the data elements in the other of the source packed data operands.

Abstract: Embodiments of systems, apparatuses, and methods for chained fused multiply add. In some embodiments, an apparatus includes a decoder to decode a single instruction having an opcode, a destination field representing a destination operand, a first source field representing a plurality of packed data source operands of a first type that have packed data elements of a first size, a second source field representing a plurality of packed data source operands that have packed data elements of a second size, and a field for a memory location that stores a scalar value. A register file having a plurality of packed data registers includes registers for the plurality of packed data source operands that have packed data elements of a first size, the source operands that have packed data elements of a second size, and the destination operand. Execution circuitry executes the decoded single instruction to perform iterations of packed fused multiply accumulate operations by multiplying packed data elements of the sources of the first type by sub-elements of the scalar value, and adding results of these multiplications to an initial value in a first iteration and a result from a previous iteration in subsequent iterations.

Abstract: Instructions and logic provide SIMD vector packed histogram functionality. Some processor embodiments include first and second registers storing, in each of a plurality of data fields of a register lane portion, corresponding elements of a first and of a second data type, respectively. A decode stage decodes an instruction for SIMD vector packed histograms. One or more execution units, compare each element of the first data type, in the first register lane portion, with a range specified by the instruction. For any elements of the first register portion in said range, corresponding elements of the second data type, from the second register portion, are added into one of a plurality data fields of a destination register lane portion, selected according to the value of its corresponding element of the first data type, to generate packed weighted histograms for each destination register lane portion.
