SYSTEM AND METHOD FOR SUPPORTING BOTH BULK STORAGE AND ETHERNET COMMUNICATIONS

摘要

The invention provides a master MMC/SD apparatus for simultaneously supporting bulk storage and Ethernet communication, a slave MMC/SD apparatus for simultaneously supporting bulk storage and Ethernet communication, a system composed of these two apparatuses as well as a method of operating the system. The apparatuses, system and method which simultaneously support bulk storage and Ethernet communication and which are based on MMC/SD interface enable a master apparatus with MMC/SD interface to support network function while maintaining bulk storage function as well, thus greatly expanding applicable areas of such embedded terminal apparatus with the MMC/SD interface that has bulk storage function.

主权项

1. A main MMC/SD apparatus for simultaneously supporting bulk storage and Ethernet communication, characterized in that the master MMC/SD apparatus comprises:
a master MMC/SD interface for providing access interface to a slave MMC/SD apparatus; a master MMC/SD interface drive device for controlling transfer of MMC/SD signaling over the master MMC/SD interface; a master bulk storage device for providing file system service and data management service for bulk storage; a master communication protocol stack device for achieving Ethernet communication between the master MMC/SD apparatus and the slave MMC/SD apparatus; and a master controller for controlling operations of the master MMC/SD interface drive device, the master bulk storage device and the master communication protocol stack device; wherein the master bulk storage device and the master communication protocol stack device interact with the master MMC/SD interface drive device respectively.
