  • Patent number: 10460444
    Abstract: Disclosed is a memory device including plural bit lines, plural word lines and a control circuit. The bit lines are configured to receive pixel data of an image. Each word line includes plural factor units. The factor units of each word line are configured differently according to plural factors of a filter. When processing a first area of the image by the filter, the control circuit inputs the pixel data within the first area of the image to the bit lines, and enables one of the word lines for operation. When processing a second area of the image by the filter, the control circuit maintains the pixel data within the second area overlapping the first area on the bit lines, and inputs the pixel data within the second area which doesn't overlap the first area to the bit lines, and enables another one of the word lines for operation.

  • Publication number: 20190327014
    Abstract: In an example, a communication module includes an optical transmitter, an optical receiver, and a periodical filter. The optical transmitter is configured to emit an outbound optical signal. The optical receiver is configured to receive an inbound optical signal. A first frequency of the outbound optical signal is offset from a second frequency of the inbound optical signal by an amount less than a channel spacing of a multiplexer/demultiplexer implemented in an optical communication system that includes the communication module. The periodical filter is positioned in optical paths of both the outbound optical signal and the inbound optical signal and has a transmission spectrum with periodic transmission peaks and troughs. The first frequency of the outbound optical signal may be aligned to one of the transmission peaks and the second frequency of the inbound optical signal may be aligned to one of the transmission troughs, or vice versa.
