Publication number: 20240126546Abstract: Disclosed embodiments relate to executing a vector-complex fused multiply-add instruction. In one example, a method includes fetching an instruction, a format of the instruction including an opcode, a first source operand identifier, a second source operand identifier, and a destination operand identifier, wherein each of the identifiers identifies a location storing a packed data comprising at least one complex number, decoding the instruction, retrieving data associated with the first and second source operand identifiers, and executing the decoded instruction to, for each packed data element position of the identified first and second source operands, cross-multiply the real and imaginary components to generate four products: a product of real components, a product of imaginary components, and two mixed products, generate a complex result by using the four products according to the instruction, and store a result to the corresponding position of the identified destination operand.Type: ApplicationFiled: December 28, 2023Publication date: April 18, 2024Inventors: Roman S. Dubtsov, Robert Valentine, Jesus Corbal, Milind Girkar, Elmoustapha Ould-Ahmed-Vall
