Abstract
An apparatus comprises processing circuitry, a number of vector register and a number of scalar registers. An instruction decoder is provided which supports decoding of a vector multiply-add instruction specifying at least one vector register and at least one scalar register. In response to the vector multiply-add instruction, the decoder controls the processing circuitry to perform a vector multiply-add instruction in which each lane of processing generates a respective result data element corresponding to a sum of difference of a product value and an addend value, with the product value comprising the product of a respective data element of a first vector value and a multiplier value. In each lane of processing at least one of the multiplier value and the addend value is specified as a portion of a scalar value stored in a scalar register.
