    Abstract: An example processor includes a register and an ADD low functional unit. The register stores first, second, and third floating point (FP) values. The ADD low functional unit receives a request to perform an ADD low operation and, responsive to the request: adds the first FP value with the second FP value to obtain a first sum value; rounds the first sum value to generate an ADD value; adds the first FP value with the second FP value to obtain a second sum value; subtracts the ADD value from the second sum value to generate a difference value; normalizes the difference value to obtain a normalized difference value; rounds the normalized difference value to generate an ADD low value; and sends the ADD low value to an application.

    Abstract: I n some embodiments, packed data elements of first and second packed data source operands are of a first, different size than a second size of packed data elements of a third packed data operand. Execution circuitry executes decoded single instruction to perform, for each packed data element position of a destination operand, a multiplication of a M N-sized packed data elements from the first and second packed data sources that correspond to a packed data element position of the third packed data source, add of results from these multiplications to a full-sized packed data element of a packed data element position of the third packed data source, and storage of the addition result in a packed data element position destination corresponding to the packed data element position of the third packed data source, wherein M is equal to the full-sized packed data element divided by N.

    Abstract: An Aggregate Scatter instruction is described. A processor may include a memory interface and a register to store data elements of a data structure. The data elements may be contiguously stored in a first location in a memory accessible via the memory interface. The processor may further include a decoder to decode an aggregate scatter instruction specifying a store operation for the data structure and an execution unit to contiguously store the data elements to a second storage location in the memory in response to the decoded aggregate scatter instruction. The second storage location may be identified by a starting memory address of the second storage location.
