A processing system includes a processor and a physical memory ( 500 ) with a single-size memory port ( 505 ) for accessing data in the memory. The processor is arranged to operate on data of at least a first data size and a smaller second data size. The first data size is equal to or smaller than the size of memory port. The processing system including at least one data register ( 514 ) of the first data size connected to the memory port ( 505 ), and at least one data port ( 525 ) of the second data size connected to the data register ( 525 ) and the processor for enabling access to data elements of the second size.
