Abstract:
A method, apparatus and computer program product for an external, self-initializing FIFO containing indexes of free CAM memory locations is presented. When data is sent to the CAM for a lookup, this external FIFO provides the CAM with the index of a free memory location within the CAM so that if the data word is not found in the CAM (i.e. a CAM miss), the data can be written to the designated available free entry in the CAM. Thus, if the same data word is searched in the CAM in the following cycle it will result in a hit.
