In this paper we present three specialized architectures for optical flow computation based on: i) an ASIC in CMOS standard cell technology, ii) a single DSP TMS320C40, and ii) a TMS320C40-based multiprocessor. The pros and cons of each architecture are discussed. keywords: optical flow estimation, ASIC, multi-DSP

First published May 29, 2009; doi:10.1152/ajplung.00020.2009.— Acid-sensing ion channels (ASIC) are voltage-insensitive, cationic channels that have recently been identified in vascular smooth muscle (VSM). It is po...

Some image processing applications (e.g. computer graphics and robot vision) require the rotation, scaling and translation of digitized images in realtime (25-30 images per second). Today’s standard image processors can not meet this timing constraint so other solutions have to be considered. This paper describes a multi-ASIC solution which is capable of doing the image processing tasks in real...

Acid-sensing ion channels (ASICs) are voltage-insensitive cation channels responding to extracellular acidification. ASIC proteins have two transmembrane domains and a large extracellular domain. The molecular topology of ASICs is similar to that of the mechanosensory abnormality 4- or 10-proteins expressed in touch receptor neurons and involved in neurosensory mechanotransduction in nematodes....

Acid-sensing ion channels (ASICs) are emerging as fundamental players in the regulation of neural plasticity and in pathological conditions. Here we showed that lead (Pb2+), a well known neurotoxic metal ion, reversibly and concentration-dependently inhibited ASIC currents in the acutely dissociated spinal dorsal horn and hippocampal CA1 neurons of rats. In vitro expression of ASIC subunits in ...
