A local FIFO memory 2 is provided within a local RAM memory 4 to provide access to source data values. A local controller 10 manages the asynchronous fetching of source data values to the local FIFO memory 2 and the optional writing back of these data values after processing to a source/sync memory 32 . One or more local head pointers and one or more local tail pointers are used by the local memory controller 10 to manage storage within the local FIFO memory 2 which is configured as a circular buffer; The remaining space within the local RAM 4 may be used for further data and the partitioning between FIFO operation and further data storage is programmable such that the same memory storage 2 can be used for multiple purposes as required.
