Abstract
A network device, also referred to as the Compression Enhanced Network Processor (CENP), with embedded parallel (or fast serial) compression and/or decompression capability. The network device may be a network processor based multi-ported switch, bridge, router, hub, or other device. The CENP may provide improved data density, efficiency and bandwidth for each port of a multi-port network switch. In one embodiment, the CENP may comprise a network processor core, a memory management unit, a memory buffer (e.g., an SRAM memory buffer), and a system memory. The CENP may comprise a compression and decompression engine. In one embodiment, the memory management unit comprises the compression and decompression engine, and thus may be referred to as a Compression Enhanced Memory Controller Unit (CEMCU).
