    摘要: The present invention discloses a content addressable memory and a method of searching data thereof. The method includes generating a hash index data item from a received input data item; searching the cache for presence of a row tag of the RAM data row corresponding to the data item of hash index; in response to presence, searching the RAM for a RAM data item corresponding to the input data item according to the corresponding row tag of the RAM data row; in response to absence, searching the RAM for a RAM data item corresponding to the input data item by using the data item of hash index; and in response to finding a RAM data item corresponding to the input data item in the RAM, outputting data corresponding to the RAM data item. The method can accelerate data search in the CAM.

    摘要: Disclosed are a method and apparatus for detecting frame boundary for a data stream received at an Ethernet FEC layer, as well as a decoding method and system for the same. The apparatus for detecting frame boundary may comprise: a buffer for buffering data in a data stream, a length of the data in the buffer being greater than one frame; a syndrome generator for calculating a current syndrome based on a first data item, a second data item, and an intermediate calculation result of a previous syndrome, wherein the first data item is the last bit in a current candidate frame, and the second data item is a bit preceding the current candidate frame; and a comparator for using the current syndrome to check whether the bit preceding the current candidate frame is a frame boundary of an Ethernet FEC layer. The apparatus for detecting frame boundary can improve the speed of frame boundary detection.
