Abstract:
Broadband Wireless Access (BWA) is a successful technology which offers high speed voice, internet connection and video. One of the leading candidates for Broadband Wireless Access is Wi-MAX; it is a technology that compiles with the IEEE 802.16 family of standards. This paper mainly focused towards the hardware Implementation of Wireless MAN-OFDM Physical Layer of IEEE Std 802.16d Baseband Transceiver on FPGA. The RTL coding of VHDL was used, which provides a high level design-flow for developing and validating the communication system protocols and it provides flexibility of changes in future in order to meet real world performance evaluation. This proposed system is analysis area and power. Also the outputs are verified using Xilinx 14.2.

Abstract:
A floating-point fused dot-product unit is presented that performs single-precision floating-point multiplication and addition operations on two pairs of data in a time that is only 150% the time required for a conventional floating-point multiplication. When placed and routed in a 45nm process, the fused dot-product unit occupied about 70% of the area needed to implement a parallel dot-product unit using conventional floating-point adders and multipliers. The speed of the fused dot-product is 27% faster than the speed of the conventional parallel approach. The numerical result of the fused unit is more accurate because one rounding operation is needed versus at least three for other approaches.

The proposed technique initially reduces the number of multiplications per input sample and additions per input sample by 83% in comparison with individual implementation of each standard’s filter while designing a root-raised-cosine finite-impulse response filter for multi-standard DUC for three different standards. In the next step, a 2-bit binary common sub-expression (BCS)-based BCS elimination algorithm has been proposed to design an efficient constant multiplier, which is the basic element of any filter. This technique has succeeded in reducing the area and power usage by 41% and 38%, respectively, along with 36% improvement in operating frequency over a 3-bit BCS-based technique reported earlier, and can be considered more appropriate for designing the multi-standard DUC. The proposed architecture of this paper analysis the logic size, area and power consumption using Xilinx 14.2.

Abstract:
In this brief, a low-cost low-power all-digital spread spectrum clock generator (ADSSCG) is presented. The proposed ADSSCG can provide an accurate programmable spreading ratio with process, voltage, and temperature variations. To maintain the frequency stability while performing triangular modulation, the fast-relocked mechanism is proposed. The proposed fast-relocked ADSSCG is implemented in a standard performance 90-nm CMOS process, and the active area is 200 µm × 200 µm. The experimental results show that the electromagnetic interference reduction is 14.61 dB with a 0.5% spreading ratio and 19.69 dB with a 2% spreading ratio at 270 MHz The power consumption is 443 µW at 270 MHz with a 1.0 V power supply.

Abstract:
We are briefly discussing the logic operations are involved in the CSLA (conventional carry select adder) and the square root conventional carry select adder. We have discard the all the extra logic operations present in the conventional CSLA. In the proposed system carry selection is take place in before the final sum calculation. The proposed system achieves the optimization in the logic units. Finally the FPGA synthesis results shows to achieves a design the low power architecture for CSLA.

In this paper, an exportable application-specific instruction-set elliptic curve cryptography processor based on redundant signed digit representation is proposed. The processor employs extensive pipelining techniques for Karatsuba–Ofman method to achieve high throughput multiplication. Furthermore, an efficient modular adder without comparison and a highthrough put modular divider, which results in a short datapath for maximized frequency, are implemented. The processor supports the recommended NIST curve P256 and is based on an extended NIST reduction scheme. The proposed architecture of this paper analysis the logic size, area and power consumption using Xilinx 14.2.

Abstract: We are discussed about the built in generation for logic blocks. The advantage of this technique is identifying the similar characteristics of the each logical block. Functional broadside tests are important for addressing overtesting of delay faults as well as avoiding excessive power dissipation during test application. Finally to analysis the performance of the built in generation technique and compare to existing system.
