Abstract
The control module for rearranging main spared device composed of the detecting sub module, the command sending sub module and the executing sub module is realized by using the field programmable gate array (FPGA) in communication device. When a fault happened in the main device being detected, the detecting sub module informs the command sending sub module, which sends the command to the executing sub module to carry out and complete the rearrangement procedure. In the invention, the rearranging functions are realized by hardware. Thus, the rearranging speed is increased greatly. Moreover, when the rearrangement procedure is carried out, there is no spike generated. Thus, the rearranging time can be decreased further. The invention omits the MUX chip, saving the area of the board in communication devices.
