Abstract/Summary In the early 21st century, more researchers are exploring the knowledge-based technique in solving the hardware/software partitioning process replacing the common heuristic approach. By utilising the knowledge-based approach, this could help to reduce the search space in finding a feasible partitioning solution. Meanwhile, in another research field, the Bayesian Network analysis has been attracting attention for various applications. One of the latest trends is to use the Bayesian Network to solve the partitioning problem. In this thesis, we present our novel algorithm that combines the Bayesian Network with the Constraint Satisfaction Problem (CSP) to perform the partitioning and scheduling process. Our methodology supports a multi-processor embedded system. This thesis also presents our new equation to represent the linking knowledge between nodes to improve the Bayesian Network analysis evaluation process. A new metric to represent the propagation information has also been introduced in this thesis. This research work is part of a larger reconfigurable smart camera project. Hence, our targeted platform is FPGAs. Since there is limited logic space on an FPGA and we have the requirement for real-time throughput, we have also included the area and time constraint conditions in our proposed algorithm. In order to demonstrate the efficiency of our algorithm, we have performed several experiments including the use of JPEG encoder as a demonstration of real image processing application on a smart camera system. We then continue to increase the number of nodes in a task-graph using a random task generator, TGFF, to test the efficiency and evaluate the computation time of our algorithm. The results from the experiment indicate that our Bayesian Network-based partitioning and scheduling algorithm can produce promising codesign solutions.
