APEX Integrated Content Addressable Memory (CAM)
Greatly Accelerates Applications Requiring List Data Searches
Altera APEX Devices: Only Programmable Logic Devices with
APEX Applications
Ethernet address look-up Internet protocol filtering Data compression Pattern recognition Cache tags Fast look-up routing tables High-bandwidth packet searches data switches, firewalls, bridges, routers
Accelerates Fast Searches Content-addressable memory (CAM), memory technology developed from random access memory (RAM), accelerates applications requiring fast searches databases, lists, patterns. simultaneously compares input data against entire list pre-stored entries single clock cycle, which provides extremely significant reduction search time when compared RAM. APEX Devices: Only PLDs with Altera's APEXdevices, only programmable logic devices (PLDs) offer integrated CAM, have million gates (2.67 million system gates) allow complete Designers APEX Device Densities Resources
APEX simplify applications that require searching lists tables data. APEX integrated provides significant system performance enhancements allows more efficient resource utilization system design. Available Each APEX Embedded System Block embedded system block (ESB) heart Altera® APEX architecture. APEX configured 32-word 32-bit CAM, multiple ESBs cascaded together implement wider deeper CAMs. APEX architecture provides great flexibility because designer create wide range depths widths.
