Intel的LAN芯片集包括由82586协处理器、82501串行接口和82502收发器组成的三片集以及只有82588控制器的单片集。本刊对82586(1989年第7期)、82588(1988年第7期)已经作过介绍,本文将对82501和82502的功能、结构、原理及应用加以概述,这样我们就会对LAN芯片集有个完整的认识。一、功能 82501和82502是为82586配套设计的,均符合IEEE 802.3标准和以太网标准。它们与OSI参考模型及802.3标准的对应功能如图1所示,由此可见
Intel’s LAN chipsets include a three-chip set of 82586 coprocessors, 82501 serial interfaces and 82502 transceivers, and a monolithic set of only 82588 controllers. This issue of 82586 (7 of 1989), 82588 (7 of 1988) has been introduced, this article will outline the function, structure, principle and application of 82501 and 82502, so we will LAN chipset Have a complete understanding. First, the function 82501 and 82502 is designed for the 82586, are in line with IEEE 802.3 standards and Ethernet standards. They and OSI reference model and 802.3 standard corresponding function shown in Figure 1, as can be seen
