Abstract: Techniques for copying a subset of status flags from a control and status register to a flags register in response to an instruction are described. An exemplary instruction includes a field for an opcode, the opcode to indicate execution circuitry is to copy from a first register a saturation flag value, an overflow value, and a carry value to a second register into one or more instructions of a different instruction set.

Abstract: Techniques for comparing BF16 data elements are described. An exemplary BF16 comparison instruction includes fields for an opcode, an identification of a location of a first packed data source operand, and an identification of a location of a second packed data source operand, wherein the opcode is to indicate that execution circuitry is to perform, for a particular data element position of the packed data source operands, a comparison of a data element at that position, and update a flags register based on the comparison.

Abstract: Techniques for scale and reduction of BF16 data elements are described. An exemplary instruction includes fields for an having fields for an opcode, an identification of a location of a first packed data source operand, an identification of a location of a second packed data source operand, and an identification of a packed data destination operand, wherein the opcode is to indicate that execution circuitry is to perform, for each data element position of the packed data source operands, a floating point scale operation of a BF16 data element of the first packed data source by multiplying the data element by a power of 2 value, wherein a value of the exponent of the power of 2 value is a floor value of a BF16 data element of the second packed data source, and store a result of the floating point scale operation into a corresponding data element position of the packed data destination operand.

Abstract: Techniques for matrix multiplication are described. In some examples, a single instruction having a format of fields for an opcode, one or more fields to indicate a location of a source/destination operand, one or more fields to indicate a location of a first source operand, and one or more fields to indicate a location of a second source operand is used. Wherein the opcode is to indicate that execution circuitry is to: multiply values from corresponding data elements of the first and second sources, add a first subset of the multiplied values to a first value from the source/destination operand and store in a first data element position of the source/destination operand, and add a second subset of the multiplied values to a second value from the source/destination operand and store in a second data element position of the source/destination operand.

Abstract: Disclosed embodiments relate to executing a vector multiplication instruction. In one example, a processor includes fetch circuitry to fetch the vector multiplication instruction having fields for an opcode, first and second source identifiers, and a destination identifier, decode circuitry to decode the fetched instruction, execution circuitry to, on each of a plurality of corresponding pairs of fixed-sized elements of the identified first and second sources, execute the decoded instruction to generate a double-sized product of each pair of fixed-sized elements, the double-sized product being represented by at least twice a number of bits of the fixed size, and generate an unsigned fixed-sized result by rounding the most significant fixed-sized portion of the double-sized product to fit into the identified destination.

Abstract: Embodiments detailed herein relate to matrix operations. In particular, the loading of a matrix (tile) from memory. For example, support for a loading instruction is described in at least a form of decode circuitry to decode an instruction having fields for an opcode, a source matrix operand identifier, and destination memory information, and execution circuitry to execute the decoded instruction to store each data element of configured rows of the identified source matrix operand to memory based on the destination memory information

Abstract: An apparatus and method for complex matrix multiplication. For example, one embodiment of a processor comprises: a decoder to decode a first complex matrix multiplication instruction; execution circuitry to execute the first complex matrix multiplication instruction, the execution circuitry comprising parallel multiplication circuitry to multiply real values from the first plurality of real and imaginary values with corresponding real values from the second plurality of real and imaginary values to generate a first plurality of real products, to multiply imaginary values from the first plurality of real and imaginary values with corresponding imaginary values from the second plurality of real and imaginary values to generate a second plurality of real products; and addition/subtraction circuitry to subtract each real product in the second plurality of real products from a corresponding real product in the first plurality of real products to produce a corresponding real value in the result matrix. The decoder may also decode and the execution circuitry may execute a second complex matrix multiplication instruction to multiply real and imaginary values from the first plurality with corresponding imaginary and real values, respectively, from the second plurality to generate first and second pluralities of imaginary products, and to add corresponding imaginary products to produce a corresponding imaginary value in the result matrix.
