Automated programming of a ring-structured multiprocessor digital filter IC
M.J. Werter, Alan N. Willson · 2002
A computer algorithm is described that automatically writes optimal programs for the implementation of arbitrary digital filter structures on parallel processors. The algorithm has been adapted particularly for programming a DSP chip with multiple processors arranged in a ring-type topology. The algorithm starts from a netlist describing a desired digital filter structure. It can check all possible timing schedules and all possible distributions of the operations over the parallel processors, taking into account the constraints imposed by the multiprocessor topology and the processors' architecture. The algorithm's output is a set of programs for the parallel processors which causes them to implement the given digital filter.
