Design of an optimal loosely coupled heterogeneous multiprocessor system

This paper presents an approach for mapping tasks optimal to hardware and software components in order to design a real-time system. The tasks are derived from an algorithm and are represented by a task-graph. The performance of the algorithm on the resulting real-time system will meet the specified timing constraints. Some of the hardware components are programmable and others are application specific hardware processors. We propose a powerful MILP (Mixed Integer Linear Program) model with and without functional pipelining. The efficiency of the method is demonstrated with practical examples
