Evaluations of waved-shift registers for the multiplexed bus

In this Paper, waved-shift registers for the multiplexed bus are developed and evaluated. The multiplexed bus is needed for HIPS (Host-based Intrusion Prevention System) in 4G mobile communications. Because an FPGA (Field-Programmable Gate Array) has been used for the multiplexed bus, there is a problem where it doesn't work at over 1 GHz. Then, the use of the FPGA leads to increase in power consumption. In this work, by using 180 nm C-MOS (Complementary Metal-Oxide Semiconductor) technology, waved-shift registers necessary for the multiplexed bus are developed. Furthermore, the comparative evaluations of the waved-shift registers are executed by using the conventional shift register that operates at 2GHz. As a result, the waved-shift registers are revealed to have surpassed all the points of throughput, power consumption and area.
