Designing a Control Application by Using a Specialized Multi-Core Soft Microprocessor

Abstract Computationally intensive algorithms for closed loop control and similar systems today can be implemented using reconfigurable FPGA devices. One approach is using soft microprocessor designs and implementing the algorithms as programs. This paper reports about a case study within an ongoing project that investigates a multi-core soft microprocessor solution for a closed-loop control application. Requirements within the project lead to a specialized processor design. Some results from experimental work are presented, demonstrating feasibility and efficiency of the approach.
