Tuned to the needs of handheld and battery powered devices, the ELP-11 implements the complete TCP/IP protocol stack and associated security requirements in a low gate count, ultra-low power design that is readily integrated into either COT or ASIC design flows. The ELP-11 offers significant power dissipation advantages compared with embedded processors executing software protocol stacks. Other advantages include simplification of system integration, elimination of costly performance tuning activities associated with embedded TCP/IP and security stacks, and the liberation of scarce processor cycles for value-added, end-user oriented processing.
Two related phenomena arise in wireless embedded and handheld devices built for today’s high speed cellular and WLAN networks. First, the amount of processing required per bit of communication becomes prohibitive as data rates increase（MIPS/Mbps）. This situation is made even worse by the much higher bit error rates in wireless environments. Second, the energy required to perform that processing is a serious drain that shortens battery lifetimes, limiting the availability and usefulness of these devices（mW/Mbps）.
