Analysis of one basic cycle of a class of digital signal processing algorithms

The design and analysis of software which implements digital signal processing (DSP) algorithms on multiprocessor systems is examined. The DSP algorithms that are considered exhibit certain characteristics which are common of DSP algorithms used in communication and control systems. The analysis methods developed use linear complexity algorithms to analyze the software that implements the DSP algorithms. The first step involves finding the repeat factors associated with a basic cycle of the algorithm. Using these repeat factors it is straightforward to (1) find the precedence relationships between tasks and finally a feasible schedule for the multiprocessor, and (2) coordinate and organize the efforts to optimize the software
