The invention provides a method and system for performing additional processing on CAM hit results, in which the additional processing does not add to the complexity or size of the CAM chip, can be altered after manufacture of the CAM chip, and does not delay other operations of the CAM. The CAM hit results are presented as indices from the CAM and sent to a hit result register file where they are stored. The contents of the hit result register file can be processed by other hardware or software coupled to the CAM. The index associated with the CAM input tag can be accessed using the hit result register file and a register indirect operation. The index associated with the CAM input tag can be used for CAM management functions in conjunction with (such as in parallel or pipelined) other CAM functions.
