Abstract
An apparatus and method are provided for updating one or more pluralities of pointers (i.e. one or more vector pointers) which are used for accessing one or more pluralities of data elements (i.e. one or more vector data elements) in a multi-ported memory. A first register file holds the vector pointers, a second register file holds stride data, and a plurality of functional units combine data from the second register file with data from the first register file. The results of combining the data are transferred to the first register file and represent updated vector pointers. Furthermore, a third register file is provided for holding modulus selector data to specify the size of a circular buffer for circular addressing.
