Abstract: A method is described that includes reading a first read mask from a first register. The method also includes reading a first vector operand from a second register or memory location. The method also includes applying the read mask against the first vector operand to produce a set of elements for operation. The method also includes performing an operation of the set elements. The method also includes creating an output vector by producing multiple instances of the operation's result. The method also includes reading a first write mask from a third register, the first write mask being different than the first read mask. The method also includes applying the write mask against the output vector to create a resultant vector. The method also includes writing the resultant vector to a destination register.

Abstract: Embodiments of systems, apparatuses, and methods for chained fused multiply add. In some embodiments, an apparatus includes a decoder to decode a single instruction having an opcode, a destination field representing a destination operand, a first source field representing a plurality of packed data source operands of a first type that have packed data elements of a first size, a second source field representing a plurality of packed data source operands that have packed data elements of a second size, and a field for a memory location that stores a scalar value. A register file having a plurality of packed data registers includes registers for the plurality of packed data source operands that have packed data elements of a first size, the source operands that have packed data elements of a second size, and the destination operand. Execution circuitry executes the decoded single instruction to perform iterations of packed fused multiply accumulate operations by multiplying packed data elements of the sources of the first type by sub-elements of the scalar value, and adding results of these multiplications to an initial value in a first iteration and a result from a previous iteration in subsequent iterations.
