Abstract
This work explores various solutions to implement an application using runtime reconfigurable field programmable gate arrays (FPGA). The example is a mechatronic control system which has to adapt its behavior from time to time. Our model is a task-graph where every task is associated with an hardware module characterized by its required FPGA resource and its execution time. We propose various mappings of the tasks onto the FPGA. For the implementation of the tasks themselves the computation technique known as distributed arithmetic is used. We achieve numerous alternatives with different resource consumptions and execution times for every task. We estimate these characteristics and compare them to synthesis results. The received values are used to get the characteristics of the over-all system. The results show that the optimal mapping depends on the application timing constrains, on the complexity of the tasks as well as on the reconfiguration speed of the used FPGA.
