DUAL MODE CODING/DECODING APPARATUS OF LINE CODE USING CODE DETECTION AND METHOD THEREOF

摘要

PURPOSE: A dual mode coding/decoding apparatus of a line code using a code detection and a method thereof are provided to increase the initializing speed by using a received code word on an operation determination of a dual mode system. CONSTITUTION: A management register(100) stores a control signal for selecting an operation of a MB810 coder(105) and a 8B/10B coder(110) and provides the stored selection control signal to the MB810 coder(105) and the 8B/10B coder(110). The MB810 coder(105) is operated by the selection control signal provided from the management register(100) and codes 32bit data of 4 lane transferred from an MAC(Media Access Control) to transfer it to the other decoding unit through a communication line. The 8B/10B coder(110) is operated by the selection control signal provided from the management register(100) and codes 32bit data of 4 lane transferred from an MAC(Media Access Control) to transfer it to the other decoding unit through a communication line. A coding-side 2:1 multiplexer(120) selects an output of the MB810 coder(105) and the 8B/10B coder(110) by the selection signal provided from the management register(100) to send the same.
