A power efficient router architecture to increase the performance in a NoC interconnect is suggested in this paper. Static power reduction by using power-gating techniques has been extensively discussed in the past. More recent papers implement router architectures to resolve the issues in power gating such as early wake-up latency and energy dissipation, thereby achieving high performance and reduction in static power. The work proposed in this paper modifies on a recent router architecture that remedied the early wake-up latency overhead and achieved significant power savings. The proposed LPSQ router architecture provides an additional reduction in dynamic power and area overhead by 20.2% and 24.5%, respectively, without degrading the overall system performance.

Many applications such as image processing and multipliers are resilient to inexactness or approximations in their underlying computations. This is the basic concept of approximate computation. The resulting degradation in output quality can be traded off to develop more energy efficient and high performance hardware systems. In this context, approximate circuit design is an emerging paradigm that has recently received considerable research attention. Many applications such as signal processing and image processing requires the use of multipliers in its core operating system. The fundamental objective of a multiplier is that it must be efficient in power and operate at high speed. The aim is to design the best possible radix 4 booth multiplier using approximate computing. The work proposed in this paper is an extended application to an existing and recent work in approximate adder design SARA which is an Accuracy Configurable Adder (ACA). A radix 4 approximate booth multiplier application is proposed in this paper which has significant improvement in power, speed and accuracy compared to the earlier approaches in approximate booth multipliers. The comparison is performed with the conventional radix 4 booth multiplier and there is a 72% and 17% reduction in power and delay respectively.

With increased complexity in digital circuits, efficient performance of involved circuitry has become the part and parcel of the digital signal processors (DSPs). In this paper, we have designed an efficient FIR filter for fixed and reconfigurable applications by embedding an area, and delay efficient carry select adder (CSLA), implemented by optimizing the redundancies in the logical operations in conventional and BEC-based CSLA. The proposed CSLA involves less area and delay than BEC-based CSLA and conventional CSLA. Here the carry operation is scheduled before the ultimate sum unlike the traditional method. Having desirably less output area and delay this becomes the best choice for FIR filter of transpose form. For the reconfigurable filter design, it is seen that the delay is reduced by 26.66%, and for MCM-based filter, the delay is reduced by 20.23%. The efficacy of the proposed design is accompanied by 15% reduction in area. © Springer Nature Singapore Pte Ltd. 2019.
