SYSTEMS AND METHODS FOR EXECUTING A FUSED MULTIPLY-ADD INSTRUCTION FOR COMPLEX NUMBERS - A simplified explanation of the abstract
This abstract first appeared for US patent application 18399473 titled 'SYSTEMS AND METHODS FOR EXECUTING A FUSED MULTIPLY-ADD INSTRUCTION FOR COMPLEX NUMBERS
Simplified Explanation
The abstract describes a method for executing a vector-complex fused multiply-add instruction, which involves performing complex number calculations on packed data elements.
- The method includes fetching an instruction with specific identifiers for source and destination operands storing complex numbers.
- The instruction is decoded, and data associated with the operands is retrieved for computation.
- For each packed data element position, the real and imaginary components are cross-multiplied to generate four products.
- A complex result is generated using the four products according to the instruction, and the result is stored in the corresponding position of the destination operand.

Original Abstract Submitted
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.
