Abstract: The routers in Network on Chips (NoCs) are used to transmit the data among the Processing Elements (PEs) in the field, and it can be done through transmission links between the routers. Traditionally, the data transmission between the PEs of NoC is carried out by the parallel bus which consumes more power, leads to be complex routing strategies and occupies more area within the field. Instead of parallel bus, serializes and deserialisers are used for serial data transmission, which consumes very less power and area than traditional method. To implement serialiser-deserialiser at the transceiver in the router for on chip communication, a three-level encoding technique is implemented in this design, which eliminates power hungry blocks in earlier works, such as Phase Locked Loops, Feed Forward Equalizers, Decision Feedback Equalizers and the repeaters along the transmission line. In this paper, a low-power transceiver is pro-posed using modified C2MOS flip flop and Dynamic TGMS flip flop circuits in order to minimize the delay. The power reduction of 35.683 and the delay reduction of 44.71 were achieved in the proposed transceiver than the NAND gate based D flip flop transceivers.
