ABSTRACT:
A local FIFO memory2is provided within a local RAM memory4to provide access to source data values. A local controller10manages the asynchronous fetching of source data values to the local FIFO memory2and the optional writing back of these data values after processing to a source/sync memory32. One or more local head pointers and one or more local tail pointers are used by the local memory controller10to manage storage within the local FIFO memory2which is configured as a circular buffer; The remaining space within the local RAM4may be used for further data and the partitioning between FIFO operation and further data storage is programmable such that the same memory storage2can be used for multiple purposes as required.
