Abstract: Disclosed embodiments relate to a new instruction for performing data-ready memory access operations. In one example, a system includes circuits to fetch, decode, and execute an instruction that includes an opcode, at least one memory location identifier identifying at least one data element, a register identifier, a data readiness indicator identifying at least one data access condition, and a data readiness mask, wherein the execution circuit is to, for each data element of the at least one data element, determine whether a memory request for the data element satisfies the at least one data access condition identified by the data readiness indicator, and in response to determining that the data access condition: generate a prefetch request for the data element, and set a value in a corresponding data element position of the data readiness mask to indicate that the memory request for the data element does not satisfy the at least one data access condition.

Abstract: An apparatus and method for loop flattening and reduction in a SIMD pipeline including broadcast, move, and reduction instructions. One embodiment of a processor comprises: a decoder to decode a broadcast instruction to generate a decoded broadcast instruction identifying a plurality of operations, the broadcast instruction including an opcode and first and second source operands, and having a split value associated therewith; and execution circuitry to execute the operations of the decoded broadcast instruction to copy a first data element specified by the first source operand to each of a first set of contiguous data element locations in a destination register and to copy a second data element specified by the second source operand to a second set of contiguous data element locations in the destination register, wherein the first and second sets of contiguous data element locations are determined in accordance with the split value.

Abstract: Systems, methods, and apparatuses for executing an instruction are described. In some embodiments, the instruction includes at least an opcode, a field for a packed data source operand, and a field for a packed data destination operand. When executed, the instruction causes for each data element position of the source operand, multiply to a value stored in that data element position all values stored in preceding data element positions of the packed data source operand and store a result of the multiplication into a corresponding data element position of the packed data destination operand.

Abstract: Disclosed embodiments relate to instructions for dual-destination type conversion, accumulation, and atomic memory operations. In one example, a system includes a memory, a processor including: a fetch circuit to fetch the instruction from a code storage, the instruction including an opcode, a first destination identifier, and a source identifier to specify a source vector register, the source vector register including a plurality of single precision floating point data elements, a decode circuit to decode the fetched instruction, and an execution circuit to execute the decoded instruction to: convert the elements of the source vector register into double precision floating point values, store a first half of the double precision floating point values to a first location identified by the first destination identifier, and store a second half of the double precision floating point values to a second location.
