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 systems and methods for performing instructions specifying horizontal tile operations. In one example, a processor includes fetch circuitry to fetch an instruction specifying a horizontal tile operation, a location of a M by N source matrix comprising K groups of elements, and locations of K destinations, wherein each of the K groups of elements comprises the same number of elements, decode circuitry to decode the fetched instruction, and execution circuitry to respond to the decoded instruction by generating K results, each result being generated by performing the specified horizontal tile operation across every element of a corresponding group of the K groups, and writing each generated result to a corresponding location of the K specified destination locations.

Abstract: An apparatus and method are described for performing a bit reversal and permutation on mask values. For example, a processor is described to execute an instruction to perform the operations of: reading a plurality of mask bits stored in a source mask register, the mask bits associated with vector data elements of a vector register; and performing a bit reversal operation to copy each mask bit from a source mask register to a destination mask register, wherein the bit reversal operation causes bits from the source mask register to be reversed within the destination mask register resulting in a symmetric, mirror image of the original bit arrangement.

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.
