Abstract
An apparatus, method and computer program are described, the apparatus comprising decode circuitry configured to decode instructions, and processing circuitry responsive to the instructions decoded by the decode circuitry to perform data processing. In response to the decode circuitry decoding a memory copy size determining instruction specifying as operands a source memory address, a destination memory address and a total number of bytes to be copied from a source block of memory locations indicated by the source memory address to a destination block of memory locations indicated by the destination memory address, the processing circuitry is configured to determine, based on at least one of the source memory address and the destination memory address, a memory copy size indicating value indicative of a subset of the total number of bytes to be copied. A data transfer instruction is also described.
