Enhancement for power is one of the most important elements in modern Integrated Circuits (ICs) design [10]. However, the major part of power is consumed by the clock network generally dominates the dynamic power of the chip due to its most important Switching rate. Data-Driven Clock-Gating (DDCG) and Multi-Bit Flip-Flops (MBFFs) in which several FFs are clustered and share mutual clock driver are two effective low power design technique which is commonly used by VLSI designer [9]. In this project, present reduce the clock power consumption by using the Multi-Bit Flip-Flops (MBFFs) technique for the sequential circuits. Also, present the benefits of applying to merge 1-bit flip-flops into some multi-bit flip-flop for clock power saving. This paper is focused on various low power techniques.

Abstract


Enhancement for power is one of the most important elements in modern Integrated Circuits (ICs) design [10]. However, the major part of power is consumed by the clock network generally dominates the dynamic power of the chip due to its most important Switching rate. Data-Driven Clock-Gating (DDCG) and Multi-Bit Flip-Flops (MBFFs) in which several FFs are clustered and share mutual clock driver are two effective low power design technique which is commonly used by VLSI designer [9]. In this project, present reduce the clock power consumption by using the Multi-Bit Flip-Flops (MBFFs) technique for the sequential circuits. Also, present the benefits of applying to merge 1-bit flip-flops into some multi-bit flip-flop for clock power saving. This paper is focused on various low power techniques. The multi-bit flip-flop is used to reduce the dynamic clock power Technique of multi-bit flip-flops are studied and discuss hears. An algorithm used to find out mergeable flip-flop are also discussed. It is observed that multi-bit flip-flop techniques are suitable for dynamic clock power reduction. The 8.1 % and 12.1 % improvement in dynamic power reduction has been observed in a case of M-Bit FF implementation over the conventional approach.
