SAA9730 from Philips Semiconductors is a highly integrated ASIC targeted for Windows-Based Terminals (Thin client) and Internet Access Terminal markets. In a SAA9730 Windows Based Terminal system, the applications run on a host server. There is no hard disk associated with each of these client systems, and all the clients use the server hard disk. The windows based terminal connects to the server through a 10/100 Ethernet LAN, integrated into SAA9730. The three-IC solution for a WBT (Windows Based Terminal) includes a CPU, a CPU interface and SAA9730. The CPU processes the network commands and instructs the SAA9730 to do the processing.
