“…The opportunities for pipelining and computational latency the main limitation in the design proposed in [11,12] due to the inner feedback of the repetitive IIR filters. Many studies are presented an optimisations design approach such as dispersed look ahead [13,14], clustered look ahead [14,15] and distributed look ahead [16,17]. All these methods increased the operating frequency using superfluous poles allowing pipelining [18,19].…”

“…This computation work is required in advance to realise the actual filter. On the other hand, some research works based on optimal design is offered to minimize the consumed computational time, however, the attempt still limited [13][14][15][16][17][18][19][20].…”

In this paper, an eight order efficient digital infinite impulse response filter is designed to improve the signal to noise ratio (SNR) and minimise the hardware and power consumption. For this task, an optimisation method has been adapted to reduce the root mean square error and hardware usage. The filter has been designed and analysed using Matlab and Modelsim, the implementation has been synthesis on Xilinx Spartan 3E-100 (xc3s100e) field-programmable gate array board. Moreover, an optimisation process using parallel algorithm has bee adapted for further reduction in the hardware area and power consumption. -Iraq, 1976) is an assist prof. in electronics engineering at University of Thi-Qar/Iraq. His B.Sc. degree in electrical engineering and his M.Sc. degree in electronic and communication engineering were granted from University of Mustansiriyah, Baghdad, Iraq in 1998 and 2000 respectively. Later he was awarded his PhD degree in electronic and electrical engineering from University of Bath, Bath, UK, in 2013. His research interests are electrical resistivity, digital filter design, microelectronic design, digital signal processing. Dr. Al-shueli is a member in IEEE organization, Iraq Section, as well as a member in the Iraqi Engineering Union. The results show the Band Pass Filter effectively functions in real time recording application with significant improvement in the SNR which could achieve high-velocity selective resolution. The present work offers a structure of implementing a band-pass filter on FPGAs using a nonlinear digital filter shows a significant saving of 25.4% in power consumption and 29.9% of the hardware size comparing with the latest algorithm of IIR filter design. Consequently, this is an essential development to enhance the neural signals to be adopted as reference or control signals in artificial limbs devices.

“…In the pipeline processing of recursive dynamical systems and infinite impulse response (IIR) filters, the recursive systems are to be reformulated into a look-ahead filter form. The basic concept of the look-ahead filter is to make the current output of the filter independent of a desirable number of the immediate past outputs, while the input-output properties of the original recursive system are preserved [6], [10], [8].…”

A linear look-ahead filter is a model of digital dynamical systems and infinite impulse response (IIR) filters for fast pipeline processing in very large scale integration (VLSI) implementation of the digital systems. Two essential problems to be dealt with in the design of look-ahead filters are stability and computational complexity of the filter. In this paper, a new periodic scheme is proposed to stabilize the-step look-ahead filter and provide minimum amount of computation in digital implementation of the filter.
