摘要
Abstract
With the rapid development of the embedded Web,the communication demand among different embedded devices through the Internet becomes increasingly intense,especially in the industrial monitoring field. The customized 32⁃bit processor embedding MAC module was taken as the hardware platform,which was developed by the project group itself. And on this ba⁃sis,the network drive of descriptor⁃based DMA transfer mechanism was designed. In order to realize the functions of stable data communication and Web browser,the protocol stack LwIP of the embedded TCP/IP was performed with transplantation without operating system. The data management method and bottom⁃layer port inside the protocol stack are analyzed in detail. The test re⁃sults show that the LwIP is suitable for the the industrial remote monitoring,and can realize stable communication while ensuring the high speed and low memory consumption.关键词
