Abstract: Embodiments of systems, apparatuses, and methods for fused multiple add. In some embodiments, a decoder decodes a single instruction having an opcode, a destination field representing a destination operand, and fields for a first, second, and third packed data source operand, wherein packed data elements of the first and second packed data source operand are of a first, different size than a second size of packed data elements of the third packed data operand. Execution circuitry then executes the decoded single instruction to perform, for each packed data element position of the 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 apparatus is described having instruction execution logic circuitry to execute first, second, third and fourth instruction. Both the first instruction and the second instruction insert a first group of input vector elements to one of multiple first non overlapping sections of respective first and second resultant vectors. The first group has a first bit width. Each of the multiple first non overlapping sections have a same bit width as the first group. Both the third instruction and the fourth instruction insert a second group of input vector elements to one of multiple second non overlapping sections of respective third and fourth resultant vectors. The second group has a second bit width that is larger than said first bit width. Each of the multiple second non overlapping sections have a same bit width as the second group. The apparatus also includes masking layer circuitry to mask the first and third instructions at a first resultant vector granularity, and, mask the second and fourth instructions at a second resultant vector granularity.

Abstract: Embodiments for loading and storing matrix data with datatype conversion are disclosed. In an embodiment, a processor includes a decoder and execution circuitry. The decoder is to decode an instruction having a format including an opcode field to specify an opcode, a first destination operand field to specify a first destination matrix location, and a first source operand field to specify a first source matrix location. The execution circuitry is to, in response to the decoded instruction, convert data elements from a plurality of source element locations of a first source matrix specified by the first source matrix location from a first datatype to a second datatype to generate a plurality of converted data elements and to store each of the plurality of converted data elements in one of a plurality of destination element locations in a first destination matrix specified by the first destination matrix location.

Abstract: A method of an aspect includes receiving an instruction indicating a destination storage location. A result is stored in the destination storage location in response to the instruction. The result includes a sequence of at least four non-negative integers in numerical order with all integers in consecutive positions differing by a constant stride of at least two. In an aspect, storing the result including the sequence of the at least four integers is performed without calculating the at least four integers using a result of a preceding instruction.
