Abstract

Sensor systems for robotics and autonomous systems usually require small-sized and power-aware dedicated solutions for their realization. Therefore, an embedded system is the first choice - but the drawback is weaker computing power compared to state-of-the-art PC-based systems. This paper describes our approach on "boosting" the computing power of embedded vision systems. Our system consists of a platform based on a Digital Signal Processor (DSP) enhanced by an additional Field Programmable Gate Array (FPGA) used as a co-processor. In our novel approach called Resource Optimized Co-processing, both the DSP and the FPGA are driven in parallel for the execution of crucial parts of the vision algorithms. Thereby, through efficient usage of system resources a significant Increase of the system performance is possible. The approach and the achievable profit in computing power is outlined in the paper. Based on an example case - the realization of a robot soccer embedded vision sensor - the usefulness and the powerfulness of our approach is demonstrated. In this demo case, by applying Resource Optimized Co-processing, the most crucial and computing-intensive function was executed twice as fast as before. Thus, we were able to fulfill the stringent real-time requirements of the vision system.
