Abstract
An apparatus and method are provided for transferring a plurality of data structures between memory and a plurality of vector registers, each vector register being arranged to store a vector operand comprising a plurality of data elements. Access circuitry is used to perform access operations to move data elements of vector operands between the data structures in memory and specified vector registers, each data structure comprising multiple data elements stored at contiguous addresses in the memory. Decode circuitry is responsive to a single access instruction identifying a plurality of vector registers and a plurality of data structures that are located discontiguously with respect to each other in the memory, to generate control signals to control the access circuitry to perform a sequence of access operations to move the plurality of data structures between the memory and the plurality of vector registers such that the vector operand in each vector register holds a corresponding data element from each of the plurality of data structures. This provides a very efficient mechanism for performing complex access operations, resulting in an increase in execution speed, and potential r…
