  The aim of this paper is to show that Digital Signal Processors (DSPs) can be
used to efficiently implement complex algorithms. As an example we have chosen
the problem of enumerating closed two-dimensional random paths. An Evaluation
Module Board (EVM) for TMS320C6201 fixed-point processor is used. The algorithm
is implemented in hand-written parallel assembly language. Some techniques are
used to fit the algorithm to the parallel structure of the processor and also
to avoid Branch and Condition-Checking tasks. Common optimization methods are
also employed to improve the execution speed of the code. These methods are
shown to yield a good efficiency in using the maximum computation power of the
processor. We use these results to obtain the area distribution of the paths.
