Technology Research, Based On The Fpga Embedded Tcp / Ip

As remote control for electric home appliances through the Internet becomes more common,many compannies today launched a new corporate initiative to develop advanced embedded solutions for Internet connectivity that can be applied to a boundless number of products such as information appliances and non-PC devices.The most representative products are CMX-MicroNet which provides true TCP/IP capabilities for 8-bit and 16-bit microprocessors and eZSOInternet Engine which provides easy Internet connectivity for 8-bit devices.Pushed by the extraordinary success of these products,we have developped a kind of embedded TCP/IP solution based on DW8051 Core. With some significant features such as low-cost and high speed,we hope it will possess its own "embedded Internet" market.The innovation of this design is the successful usage of separate CRC module and UART module,as can improve the speed and performance of this chip greatly. Such kind of efficiency improvement brought by the proposed design has been proved on Altera' s SOPC(System On a Programmable Chip). The whole system has been validated through hardware emulation platform. The core has been mapped on APEX EP20K400E and works under the frequency of 25MHZ.
