METHOD AND APPARATUS FOR EXPANDING A BACKPLANE INTERCONNECTING BUS WITHOUT ADDITIONAL BYTE SELECT SIGNALS

摘要

a process and a device for extending a bus for connection with a backplane architecture (100) in which the width of a data bus (104) can be extended without adding new lines of command selection of byte on the bus connection backplane (102).according to the present invention, the data lines and the corresponding parity lines are added to the backplane bus for connection, and the control signal lines (172, 174) are devices that use the capacity of the bus.the lines of control signals does not affect the operation of devices which are designed according to the narrower bus width, and therefore, the equipment may be installed in the expanded bus connecting backplane (162), as well as devices designed for r to use the data bus width size (163).
