Ripple Carry Adder

The objective of the paper is to reduce the hardware complexity of higher order FIR filter with symmetric coefficients. The aim is to design efficient Fast Finite-Impulse Response (FIR) Algorithms (FFAs) for parallel FIR filter structure with the constraint that the filter tap must be a multiple of 2. The parallel FIR filter structure based on proposed FFA technique has been implemented based on carry save and ripple carry adder for further optimization. The reduction in silicon area complexity is achieved by eliminating the bulky multiplier with an adder namely ripple carry and carry save adder. For example, for a 6-parallel 1024-tap filter, the proposed structure saves 14 multipliers at the expense of 10 adders, whereas for a six-parallel 512-tap filter, the proposed structure saves 108 multipliers at the expense of 10 adders. Overall, the proposed parallel FIR structures can lead to significant hardware savings for symmetric coefficients from the existing FFA parallel FIR filter, especially when the length of the filter is very large.

Digital Fir Filters

The digital Finite-Impulse-Response (FIR) filters are mainly employed in digital signal processing applications. The main components of digital FIR filters designed on FPGAs are the register bank to save the samples of signals, adder to implement sum operations and multiplier for multiplication of filter coefficients to signal samples. Although, design and implementation of digital FIR filters seem simple but the design bottleneck is multiplier block for speed, power consumption and FPGA chip area occupation. The multipliers are an integral part in FIR structures and these use a large part of the chip area. This limits the number of processing elements (PE) available on the chip to realize a higher order of filter. A model is developed in the Matlab/Simulink environment to investigate the performance of the desired higher order FIR filter. An equivalent FIR filter representation is designed by the Xilinx FIR Compiler by using the exported FIR filter coefficients. The Xilinx implementation flow is completed with the help of Xilinx ISE 14.5. It is observed how the use of higher order FIR filter impacts the resource utilization of the FPGA and it’s the maximum operating frequency.

Abstract Hoerl and McCormack demonstrate that although animals possess a sophisticated temporal updating system, there is no evidence that they also possess a temporal reasoning system. This important case study is directly related to the broader claim that although animals are manifestly capable of first-order (perceptually-based) relational reasoning, they lack the capacity for higher-order, role-based relational reasoning. We argue this distinction applies to all domains of cognition.
