本篇論文中，我們將針對目前屬於家庭電器的產品，提出一套架構可適用於快速整合網路功能至原有的家電中，藉此有效地縮短資訊家電產品的開發成本與時程。同時針對乙太網路媒體存取介面，提供利用硬體進行加速TCP/IP總和檢查計算。主要的焦點在資訊家電系統的硬體與軟體開發流程，其中針對包括下一代區域網路Gigabit Ethernet介面，及利用硬體進行TCP/IP總和檢查機制的討論。

In this paper, we will provide an example of SoC for Information Appliance. We will use the SoC to reduce design-time and design-cost for IA products. Simultaneously, we will also enhance the Gigabit Ethernet Media- Access-Controller (MAC) with Hardware TCP/IP Checksum module. It can alleviate the CPU loads effectively, especially in longer length packets.
