  • Pointer register indirectly addressing a second register in the processor core of a digital processor
    Patent number: 6052766
    Abstract: A first register stores a value that can be used as a pointer to indirectly address a second register. The first register is referred to as a pointer register and the pointer as a register pointer. The second register may be a conventional register that stores a conventional register value (i.e., a data value or a pointer to a data value stored in external memory) or another pointer register. In certain embodiments, a pointer register can also be used to store conventional register values. Pointer registers of the present invention can be used to implement efficiently certain types of digital processing, such as circular buffers, vector processing, convolutional processing, and partitioned processing, using data in registers rather than memory.
