MUMBAI, India, Oct. 11 -- Intellectual Property India has published a patent application (202517092274 A) filed by Arm Limited, Cambridge, U.K., on Sept. 25, for 'technique for efficient multiplication of vectors of complex numbers.'
Inventor(s) include Milanovic, Jelena; Biscondi, Eric; and Najem, Mohamad Mathieu.
The application for the patent was published on Oct. 10, under issue no. 41/2025.
According to the abstract released by the Intellectual Property India: "Processing circuitry is provided to perform vector operations, with instruction decoder circuitry used to decode instructions from a set of instructions to control the processing circuitry to perform the vector operations specified by the instructions. Array storage that has storage elements to store data blocks is used to store at least one two-dimensional array of data blocks accessible to the processing circuitry when performing the vector operations. The set of instructions comprises a complex valued outer product instruction specifying a first source operand, a second source operand, and a destination operand, wherein each of the first source operand and the second source operand is a vector operand comprising a plurality of source data elements, each source data element is a complex number formed of a real part and an imaginary part, and the destination operand identifies a given two-dimensional array of data blocks within the array storage. The processing circuitry is responsive to the complex valued outer product instruction to perform an outer product operation using the source data elements of the first source operand and the source data elements of the second source operand in order to generate a plurality of result data elements, where each result data element is a complex number formed of a real part and an imaginary part, and where each real part and each imaginary part of each result data element is associated with one of the data blocks in the given two-dimensional array of data blocks and is used to update a value of that associated data block."
The patent application was internationally filed on Feb. 01, 2024, under International application No.PCT/GB2024/050278.
