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.
摘要翻译： 一种用于CAM的优先编码器（PE），包括多个PE块，每个PE块都接收与对应的数据阵列块中的数据条目相对应的多个匹配结果，并且用于基于物理上的数据来确定最高优先级数据条目的地址 在CAM搜索与比较操作期间在数据阵列块中的位置存储用于分配给每个PE块的用户定义的优先级值的寄存器以及用于评估优先级值的装置和由多个PE块确定的地址以选择PE块 具有最高优先级的数据输入。

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.
