hardware circular buffer
     
         {digital signal processors} which
        support hardware {circular buffers} automatically generate and
        increment {pointers} for {memory} accesses which wrap to the
        beginning of the {buffer} when its end is reached, thus saving
        the time and instructions otherwise needed to ensure that the
        address pointer stays within the boundary of the buffer, and
        speeding the execution of repetitive DSP algorithms.
