    摘要: A priority encoder (PE) for a CAM, comprising a plurality of PE blocks, each receiving a plurality of match results corresponding to data entries in a corresponding data array block and, for determining an address of a highest priority data entry based on a physical location in the data array block during a CAM search-and-compare operation a register for storing a user defined priority value assigned to each PE block and means for evaluating priority values and the address determined by the plurality of PE blocks to select a PE block having the highest priority data entry.

    摘要: A Content Addressable Memory array includes a plurality of coupled sub-blocks arranged in rows and columns. Search data received by a first sub-block in a first column of the CAM is propagated to each sub-block in the row to the last sub-block in the last column of the CAM. The search result for the CAM is selected based on the propagated search results for each row of sub-blocks and output on a side of the array opposite from the side receiving the search data.
