An apparatus and method are provided for transferring a plurality of data structures from memory into one or more vectors of data elements stored in a register bank. The apparatus has first interface circuitry to receive data structures retrieved from memory, where each data structure has an associated identifier and comprises N data elements. Multi-axial buffer circuitry is provided having an array of storage elements, where along a first axis the array is organised as N sets of storage elements, each set containing a plurality VL of storage elements, and where along a second axis the array is organised as groups of N storage elements, with each group containing a storage element from each of the N sets. Access control circuitry then stores the N data elements of a received data structure in one of the groups selected in dependence on the associated identifier. Responsive to an indication that all required data structures have been stored in the multi-axial buffer circuitry, second interface circuitry then outputs the data elements stored in one or more of the sets of storage elements as one or more corresponding vectors of data elements for storage in a register bank, each vector containing VL data elements. Such an approach can significantly increase the performance of handling such load operations, and give rise to potential energy savings. |
