1. Overview WIZnet core technology, ‘TCP/IP Offload Platform’ is ASSP and silicon-proven IP for custom ASIC, which best fits OS-less device and is compatible with any Embedded OS. Also, its fully hardwired TCP/IP algorithm guarantees line speed by on-the-fly processing architecture that is independent of main processor. Moreover, it eliminated main processor’s overhead by offloading TCP/IP processing and hence enhances overall system performance especially in multimedia streaming applications. WIZnet hardwired TCP/IP chip has been adopted worldwide both in OS-less devices (esp. DVR, Remote Control) and OS-based (esp. STB, DTV). It provides higher performance and stability than any software internet connectivity solution.

3. Why Fully Hardwired TCP/IP? l CPU Overhead from S/W TCP/IP Processing • • TCP/IP a part of Driver, Copy and Bufmgt * Source by IEEE Computer, 2004 Hardware TCP/IP Chip Software TCP/IP Stack • High from TCP/IP offload • Low from software TCP/IP bottleneck and CPU overhead • Just add TCP/IP chip as simple as Memory chip • Software porting and integration • Hard to debug • Socket programming • TCP/IP protocol & OS Kernel • Ethernet drive • Socket programming System resource • Just add TCP/IP Chip on existing system • Faster CPU & bigger Memory BOM • Low from small system resource • High from big system resource System upgrade • No need to port TCP/IP even when change platform • Need to port TCP/IP whenever change platform Remote upload • Stable to add new functions on installed system • Limited to add new functions on installed system Performance Task to develop Knowledge * Source by "Embedded Internet Technology Trend" - Embedded World (Korean monthly journal), Nov. 2005 © WIZnet All Rights Reserved 4 page
