Abstract
A parallel search engine able to receive commands via a search instruction input and data words via a search data input. The commands received, which are optionally programmable, control operation of a data dispatch unit and a result dispatch unit. The data words received are sent by the data dispatch unit as search data to a CAM module array made up of CAM modules interconnected by a cascade information bus for comparison against pre-stored comparand databases. The CAM modules of the CAM module array provide search results to the result dispatch unit which generates results, typically multiple in parallel, at a result output. Optionally, multiple of the parallel search engines may be cascaded by connection to an expansion bus to form a mega search engine.
