Infinite impulse response (IIR) filter designs mainly aims on either low area-cost or high speed or reduced power consumption. Infinite Impulse Response filters are the most important element in signal processing and communication. IIR filters can achieve filtering characteristic using less memory and calculations than a similar FIR filter. Multipliers are the basic building block in DSP, microprocessors and other applications. The system's performance is entirely dependent upon the multipliers beca have large area, long latency and consume considerable power hence there is a need to design high speed, low power consumption, regular and less area multipliers. The speed of the multipliers can be increased by reducing the number of partial prod Parallel multipliers are fastest among all multipliers. Booth multipliers are the parallel multipliers that operate on signed operands in two's complement form and have high performance, low power consumption and does not suffer from bad regularity. presents an efficient implementation of high speed parallel multiplier using Radix-4 which further used in the designing of IIR filter. Pre implemented to increase the lifespan of electronic components and increase reliability of the voltage system. Pre-charge is intended to minimize propagation delay time. Pre-charge of the power line voltages in a high voltage DC application is a preliminary mode which limits the inrush current during the power up procedure. In other systems su as vehicle applications, pre-charge will occur with each use of the system, multiple times per day.
