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.

Apparatus and method for updating pointers for indirect and parallel register access

A digital signal processor (DSP) includes a SIMD-based organization wherein operations are executed on a plurality of single-instruction multiple data (SIMD) datapaths or stages connected in cascade. The functionality and data values at each stage may be different, including a different width (e.g., a different number of bits per value) in each stage. The operands and destination for data in a computational datapath are selected indirectly through vector pointer registers in a vector pointers datapath. Each vector pointer register contains a plurality of pointers into a register file of a computational datapath.

SIMD processor with concurrent operation of vector pointer datapath and vector computation datapath

A method and system for visualizing circuit operation. In the method device activity is obtained based on one or more of measured or simulated activity. The device activity is expressed in a representation, and the expressed activity is represented in a visual form. One suitable form of activity is the simulated version of the PICA slow motion movie. The invention may apply to other simulated design data vies as well, such as switch level simulation, current density simulation, and power density simulation.
