High order notation and automated program generation for realtime signal processing

A high-order signal processing graph notation (PGN) has been developed to convert information contained on the signal processing block diagram to a tabular form that is used by a computer-based Automated Program Generator. The Automated Program Generator (APG) uses the PGN input to generate the executable code/initial program load (IPL) for a realtime signal processor called the Functional Processing Element (FPE). PGN generation is a transfer of parameters on the block diagram such as filter length and decimation to the tabular form of PGN. The PGN representation of the block diagram can be generated directly by the signal processing analyst or system engineer. The APG produces the linkage code required to sequence and schedule the execution of the realtime signal processing functions. It automatically smooths the processor computation loading for multirate signal processing tasks and performs all memory mapping and management tasks.
