Focal plane processing applications present a growing computing need for portable telecomputing and videoputing systems. This paper demonstrates the integration of digital processing, analog interface circuitry, and thin film OE devices into a compact computing package. The SIMPil architecture provides a programmable, silicon efficient SIMD processor for(More)
[Purpose] The purpose of this study was to investigate the effect of muscle vibration applied to the lower extremities on static postural balance of patients with Parkinson's disease (PD). [Subjects] Seven subjects with Parkinson's disease participated in this study. [Methods] The oscillators of vibration were attached to the muscle bellies of the tibialis(More)
— Optical interconnection through stacked silicon foundry complementary metal–oxide–semiconductor (CMOS) circuitry has been demonstrated at a data rate of over 40 Mb/s with an open eye diagram. The system consists of a 0.8-m transmitter and receiver realized in foundry digital CMOS. The use of digital CMOS enables on-chip integration with more complex(More)
This paper presents a three-dimensional, highly parallel , optically interconnected system to process high-throughput stream data such as images. The vertical optical interconnections are realized using integrated optoelectronic devices operating at wavelengths to which silicon is transparent. These through-wafer optical signals are used to vertically(More)
