    摘要： An ATM switch with multicast capability uses a feedback mechanism for resolving contentions. A multicast network reads N cells from an input queue, replicates multicast cells and translates their addresses in accordance with an external look-up table. The processed N cells are stored in a temporary buffer until information regarding the number (F) of cells fed back due to contention in the previous switching cycle is available. A rotator positions N-F cells from the temporary buffer on inputs of an output network so as to assign the cells from the temporary buffer a lower priority than a priority of the feed back cells. The output network selects the cells that can be switched to their destinations and transfers them to output ports. The cells that cannot be switched due to contention are fed back to be presented for the output network consideration in the next switching cycle. At the same time, a pointer of the input queue is decremented by a factor depending on the number of feedback cells, and the number of multicast and unicast cells in the current switching cycle.

    摘要： An image sensor array includes image sensors having photo TFTs to generate photocurrent in response to received images. The photo TFTs each have their respective gate electrodes and source electrodes independently biased to reduce the effects of dark current. Storage capacitors are coupled to each photo TFT and discharged upon generation of a photocurrent. Each storage capacitor is coupled to a readout TFT that passes a current from the storage capacitor to a data line. The photo TFT may be disposed above the storage capacitor to increase the exposed surface area of the photo TFT.
