In current inventive technology, latency, power and area are the crucial parameters to outline any kind of the algorithm on FPGA. The fundamental tool used for DSP applications is Fast Fourier Transform. FFT plays a vital role in acquiring the signal characteristics with least use of carrying out parameters. The adder plays an utmost importance. To make the best possible adder design regarding delay and area, various works have been proposed before. In proposed system, a combination different sub adders like Carry Look ahead adder (CLA), Ripple carry adder (RCA), and Carry save adder (CSA) is proposed. This reduces the delay and area but also increases the speed. The hybrid adders is proposed to represent FFT architecture inplace of conventional adders. Hybrid adder will act as a complex adder. Speed multipliers are fundamental parts of DSP systems. Multipliers are complex process and consumes more time. In order to lower the complexity multiplication, various multiplier less method are introduced. An efficient DA based complex multiplier is proposed, inplace of regular multiplier. The pipelining technique is applied only to hybrid adder. The design of Radix-2 FFT for 8 point of FFT, 1024 point of FFT is done, programmed using Verilog language. Using Xilinx 14.5i tool with Spartan 6 kit, Simulation is achieved.

Purpose To provide an overview of communication characteristics exhibited by individuals with Angelman Syndrome (AS) and special considerations associated with the design and implementation of augmentative and alternative communication (AAC) programs. Method Results of recent studies exploring individuals' uses of AAC are reviewed, with particular emphasis on factors related to individuals' acceptance and successful uses of AAC systems. Results Not applicable Conclusion Despite their inconsistent access to practices previously found to foster individuals' acceptance of AAC systems, individuals with AS demonstrate the ability to use AAC systems, including high-tech AAC devices, successfully.
