PURPOSE: A method for monitoring of back bone data is provided to monitor the required data and process data having a destination address to a board itself by registering a specific source address by comparing and selecting from a view of hardware. CONSTITUTION: NA(Node Address) and BA(Back Haul Interface Unit Address) are compared with a destination address of backbone input to 8 bit comparing parts(100,110) in a first clock. In next clock, CA(CDMA Interface Network Unit Address) is compared with a destination address of backbone input to another 8 bit comparing part(120). If input Destination Address of back bone accords with NA or BA, output of AND gate(130) maintains high, and if input Destination Address of back bone accords with CA, the 8 bit comparing part(120) maintains high. The comparing results are inputted to a final end of AND gate(150) with a monitor signal latched as high, and comparing signal is output thereby. When the monitor signal maintains high by operating as clock, the comparing signal becomes high according as output of the 8 bit comparing parts(100,110,120), and at this time data of backbone are registered in a first-input-first-output(FIFO) buffer. |
