Introduction
  NCL-2000 Wi-Fi Processor LSI integrates 802.11 a/b/g base band and the ARTESSO that is NETCLEUS’ proprietary network processor with incredible performance and ultimate low power. NCL-2000 has 802.11 driver and TCP/IP firmware being implemented, and the ARTESSO in the chip executes the firmware.
  The ARTESSO is a next generation processor, integrating 32 bits RISC and full hardware RTOS. ARTESSO has capability to operate TCP/IP more than ten times performance comparing with conventional processor with incredibly low power. Therefore NCL-2000 achieves high TCP/IP performance even under a battery-base mobile terminal system environment, because of its low power operation.
  In conventional implementation of 802.11 mobile terminals, TCP/IP firmware is implemented on a host embedded processor. But such processor does not have ability to achieve high TCP/IP performance with low power consumption. Thus the maximum TCP/IP throughput is just a few Mbps at best in the system. But a system based on the NCL-2000 realizes the theoretical limitation of TCP/IP throughput over 802.11, and the operational clock rate of ARTESSO can be even less than 30MHz then.
  In summary, the advantage of NCL-2000 is not only integrating TCP/IP and 802.11, but realizes high throughput TCP/IP with low power consumption. And it implements all the network functions in it, therefore software work can be reduced in the system development and the host processor load is dramatically lowered.
