This paper presents <i>Xetal-Pro</i> SIMD processor, which is based on <i>Xetal-II</i>, one of the most computational-efficient (in terms of GOPS/Watt) processors available today. <i>Xetal-Pro</i> supports ultra wide <i>V</i><sub><i>DD</i></sub> scaling from nominal supply to the sub-threshold region. Although aggressive <i>V</i><sub><i>DD</i></sub> scaling(More)
Visual servoing has been proven to obtain better performance than mechanical encoders for position acquisition. However, the often computationally intensive vision algorithms and the ever growing demands for higher frame rate make its realization very challenging. This work performs a case study on a typical industrial application, organic light emitting(More)
—Visual servoing, which applies computer vision as a feedback source for control, is becoming a cost effective solution for high performance mechatronic systems. However, the potential of visual servoing systems is limited by the current design methodology, which explores the cyber domain and the physical domain separately. We propose to use a(More)
abstract Visual servoing applies image sensors instead of mechanical encoders for position acquisition. It can achieve higher resolutions than mechanical encoders at comparable cost. However, visual servoing is computation intensive. Special purpose hardware is often required. This work performs a case study on organic light emitting diode (OLED)(More)
