A methodology for programming a pipeline array processor

In this note a recursive filter implementation is discussed, analyzed and programmed in the most efficient way for the FPS-AP120B array processor. The purpose of this note is not only to demonstrate a good technique for programming this filter (even though it is a noble goal by itself), but to demonstrate the methodology involved. The FPS-AP120B array processor was chosen because it has microprogrammed control parallel pipeline architecture, which is typical for a wide class of high performance array processors.
