Abstract: Disclosed embodiments relate to systems and methods for performing instructions to transform matrices into a row-interleaved format. In one example, a processor includes fetch and decode circuitry to fetch and decode an instruction having fields to specify an opcode and locations of source and destination matrices, wherein the opcode indicates that the processor is to transform the specified source matrix into the specified destination matrix having the row-interleaved format; and execution circuitry to respond to the decoded instruction by transforming the specified source matrix into the specified RowInt-formatted destination matrix by interleaving J elements of each J-element sub-column of the specified source matrix in either row-major or column-major order into a K-wide submatrix of the specified destination matrix, the K-wide submatrix having K columns and enough rows to hold the J elements.

Abstract: Disclosed embodiments relate to systems for performing instructions to quickly convert and use matrices (tiles) as one-dimensional vectors. In one example, a processor includes fetch circuitry to fetch an instruction having fields to specify an opcode, locations of a two-dimensional (2D) matrix and a one-dimensional (1D) vector, and a group of elements comprising one of a row, part of a row, multiple rows, a column, part of a column, multiple columns, and a rectangular sub-tile of the specified 2D matrix, and wherein the opcode is to indicate a move of the specified group between the 2D matrix and the 1D vector, decode circuitry to decode the fetched instruction; and execution circuitry, responsive to the decoded instruction, when the opcode specifies a move from 1D, to move contents of the specified 1D vector to the specified group of elements.

Abstract: Embodiments detailed herein relate to matrix operations. In particular, matrix (tile) multiply accumulate and negated matrix (tile) multiply accumulate are discussed. For example, in some embodiments decode circuitry to decode an instruction having fields for an opcode, an identifier for a first source matrix operand, an identifier of a second source matrix operand, and an identifier for a source/destination matrix operand; and execution circuitry to execute the decoded instruction to multiply the identified first source matrix operand by the identified second source matrix operand, add a result of the multiplication to the identified source/destination matrix operand, and store a result of the addition in the identified source/destination matrix operand and zero unconfigured columns of identified source/destination matrix operand are detailed.

Abstract: Embodiments of systems, apparatuses, and methods for dual complex number multiplication and addition in a processor are described. For example, execution circuitry executes a decoded instruction to multiplex data values from positions in source operands to a multiplier, the source operands including pairs complex numbers, calculate a real part of a product of each pair of complex numbers, add the real part of the product of a first pair of complex numbers to the real part of the product of a second pair of complex numbers to calculate a first real result, and add the real part of the product of a third pair of complex numbers to the real part of the product of a fourth pair of complex numbers to calculate a second real result, and store the results to corresponding positions in the destination operand.

Abstract: Embodiments of systems, apparatuses, and methods for performing controllable sine and/or cosine operations in a processor are described. For example, execution circuitry executes a decoded instruction to compute at least a real output value and an imaginary output value based on at least a cosine calculation and a sine calculation, the cosine and sine calculations each based on an index value from a packed data source operand, add the index value with an index increment value from the packed data source operand to create an updated index value, and store the real output value, the imaginary output value, and the updated index value to a packed data destination operand.

Abstract: Disclosed embodiments relate to apparatuses, systems, and methods for performing sort indexing and/or permutation using an index. An exemplary apparatus includes decode circuitry to decode an instruction, the instruction to include a first field to identify a location of a source vector, a second field to identify a location of a destination vector, and an opcode to indicate to execution circuitry to execute the decoded instruction to sort values of the source vector and store a result of the sort in the destination vector by generating, per each element of the source vector, an index value using one or more comparisons of the element itself and to other data elements of the source vector, and permuting the values of the elements of the source vector based upon the index values for the elements and execution circuitry to execute the decoded instruction as indicated by the opcode.
