This paper proposes compact hardware implementations of 64-bit NESSIE proposed MISTY1 block cipher for area constrained and low power ASIC applications. The architectures comprise only one round MISTY1 block cipher algorithm having optimized FO/FI function by re-utilizing S9/S7 substitution functions. A focus is also made on efficient logic implementations of S9 and S7 substitution functions using common sub-expression elimination (CSE) and parallel AND/XOR gates hierarchy. The proposed architecture 1 generates extended key with independent FI function and is suitable for MISTY1 8-rounds implementation. On the other hand, the proposed architecture 2 uses a single FO/FI function for both MISTY1 round function as well as extended key generation and can be employed for MISTY1 [Formula: see text] rounds. To analyze the performance and covered area for ASICs, Synopsys Design Complier, SMIC 0.18[Formula: see text][Formula: see text]m @ 1.8[Formula: see text]V is used. The hardware constituted 3041 and 2331 NAND gates achieving throughput of 171 and 166 Mbps for 8 rounds implementation of architectures 1 and 2, respectively. Comprehensive analysis of proposed designs is covered in this paper.

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 proposed 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.
