Abstract
Methods and apparatus for implementing an enhanced digital signal processor through the addition of modular computation units which can be operated in parallel are described. In various embodiments the computation units are implemented as configurable computation cells which are arranged to form a computation engine which supplements conventional DSP circuitry. The computation cells can be used to perform frequently used DSP functions such a cross-correlation, sorting, FIR filtering quickly without the need for extensive iterative processing. By using the computation cells of the present invention in parallel, the computation of common DSP functions can be performed quickly and resulting in improvements in DSP performance as compared to convention DSPs.
