This combination enables CAMs of virtually any size to be built while delivering excellent match time characteristics. The UTMC CAM family provides performance exceeding currently available CAMs at significantly lower costs. The UTMC CAM family targets telecommunication and data communication applications requiring large, fast table look-ups. It is also beneficial for image processing, pattern recognition, artificial intelligence learning systems, and database applications. UTMC s CAM family greatly increases the density and flexibility offered by conventional CAM products.
CAMs is ideal for the next generation of high-speed routers and switches.
The depth, width, and number of the look-up tables are dependent on the external memory size and user configuration. The association word width is also programmable with 49 widths from 1 to 8M bytes. System designers can utilize any combination of key widths, association widths, and table sizes that can be embodied in the memory provided. This allows tables to be quickly searched for a match of as many most-significant bits as possible. Longest prefix matches on 32-bit addresses can be completed in less than 300nsec.
