A Novel High Speed FPGA Architecture for FIR Filter Design
Sachin B. Jadhav,Nikhil Niwas Mane
International Journal of Reconfigurable and Embedded Systems (IJRES) , 2012, DOI: 10.11591/ijres.v1i1.268
Abstract: This paper presents the details of hardware implementation of linear phase FIR filter using merged MAC architecture. Speed of convolution operation of FIR filter is improved using merged MAC architecture. By exploiting the reduced complexity made possible by the use of sparse powers of two partial products terms coefficients, an FIR filter tap can be implemented with 2B full adders, and 2B latches, where B is intermediate wordlegnth. Word and bit level parallelism allows high sampling rates, limited only by the full adder delay. The proposed architecture is based on binary tree constructed using modified 4:2 and 5:2 compressor circuits. Increasing the speed of operation is achieved by using higher modified compressors in critical path. Our objective of work is, to increase the speed of multiplication and accumulation operation by minimizing the number of combinational gates using higher n: 2 compressors, which is required more for Array multiplier at the time of implementation of array architecture. This novel architecture allows the implementation of high sampling rate filters of significant length on FPGA Spartan-3 device (XC3S400 PQ-208). The simulation result shows convolution output of digital FIR filter which is done using Questa Sim 6.4c Mentor Graphics tool. The experimental test of the proposed digital FIR filter is done using Spartan-3 device (XC3S400 PQ-208)

Abstract: This paper presents the details of hardware implementation of modified partial product reduction tree using 4:2 and 5:2 compressors. Speed of multiplication operation is improved by using higher compressors .In order to improve the speed of the multiplication process within the computational unit; there is a major bottleneck that is needed to be considered that is the partial products reduction network which is used in the multiplication block .For implementation of this stage require addition of large operands that involve long paths for carry propagation. The proposed architecture is based on binary tree constructed using modified 4:2 and 5:2 compressor circuits. Increasing the speed of operation is achieved by using higher modified compressors in critical path. Our objective of work is, to increase the speed of multiplication operation by minimizing the number of combinational gates using higher n: 2 compressors. The experimental test of the proposed modified compressor is done using Spartan-3FPGA device (XC3S400 PQ-208).Using tree architectures for the partial products reduction network represent an attractive solution that is frequently applied to speed up the multiplication process. The simulation result shows 4:2 and 5:2 compressor output which is done using Questa Sim 6.4c Mentor Graphics tool.

Abstract: Formation of coronary artery pseudoaneurysm after percutaneous coronary intervention is rarely reported. A close review of available literature indicates a trend of growing incidence in recent times. Here, we present a case of coronary pseudoaneurysm developing in the left circumflex artery within 50 days of sirolimus-eluting stent implantation in a 47-year-old man who was treated for triple-vessel coronary artery disease. Initially, the patient refused any further treatment. However, considering the rapid growth of pseudoaneurysm and increased severity of symptoms at subsequent follow-up, we decided to treat giant pseudoaneurysm with embolization coils. The procedure was successful and the patient remained asymptomatic thereafter.

Abstract: In the present paper, Gadolinium doped in small amount on the electrical properties of Ni Cu Zn Fe Gd O (x=0.00 and 0.04) spinel ferrites were prepared 0.25 0.20 0.55 2-x x 4by double sintering ceramic technique. Room temperature resistivity increases with 3+small amount of Gd content. This increase in resistivity is attributed to the 3+ 3+unavailability of Fe ions in the lattice due to Gd content. The Dc resistivity decreases with temperature for all the samples at 0.00 and 0.04 indicating the semiconducting behavior of these samples. Room temperature Dc resistivity and activation energies shows similar trend both 0.00 and 0.04 indicating that the samples with high resistive have high activation energies and vice versa. Such results are promising ones for the high frequency application.

Abstract: Why do people work? If this question is asked to anyone, probably we will get a simple answer that they work, because there is work to be done, because they like work or they need to earn a living etc. Human nature shows a nice adaption between properisity to work and the need to maintain a complex material to work and the need to maintain a complex material culture. In order to survieve man needs, cloths house etc. and to provides all these there has to be persistent striving for the achievement of goods and cooperation in groups i.e. forming a social group where individual may work to earn their live hood /live hood.

Abstract: Background: The germ tube production in serum is a rapid method for identification of Candida. Because of the time required to prepare human serum and inherent safety problems concerned with its use, many laboratories have started using non human serum germ tube media. The objective of this study was to evaluate different media for germ tube production of C. albicans and C. dubliniensis Material and Methods: 132 C. albicans and 30 C. dubliniensis isolates were tested for germ tube production in various media like horse serum, pooled human serum, human plasma, trypticase soy broth, egg white and peptone water. Results: Out of 132 C. albicans, germ tube production was seen in 130 isolates in trypticase soy broth, 124 isolates produced germ tube in pooled human serum and horse serum. In case of C. dubliniensis (n=30), of isolates produced germ tube in trypticase soy broth and pooled human serum. In horse serum 26 isolates showed germ tube test positive Conclusion: Our study shows that trypticase soy broth is the best medium for testing germ tube production of C. albicans and C. dubliniensis. It is more stable, effective, less expensive and safe than other media.

Abstract: There are many antivirus products available in market. They provide different type of security levels to the user’s data. For their own improvement they need to compare their product with their competitors to know the difference of security levels detected for the same type malware. To do such comparisons, the companies need to analyse the actions taken by the antivirus with toaster window displayed on desktop and hence they need to compare a large number of screen-shots of those actions. This project is used for automation of all these process to provide effective and better way of screen shot analysis by extracting text from them. Hence, the purpose of this project is to analyse and classify the actions taken by an antivirus for particular malware with the help of screen shots of those actions. It reduces the manual efforts and provides an automated way recognizing the activities done by an antivirus.

Abstract: Ginger (Zingiber officinale Roscoe Family- Zingiberaceae), have been used in Chinese and Indian folk medicine for centuries. There are no reported UV‐visible methods for quick estimation of this extract, which is necessary in the development of suitable formulations for this drug. Hence, a simple UV spectroscopic method was developed for direct estimation of this extract. Ginger rhizome extract obtained from simple maceration process. Calibration curve of rhizome extract was prepared in methanol on three consecutive days at λmax 281.40 nm. The absorbance values (mean of three determinations) with their standard deviations at different concentration in the range of 20‐100 μg/ml was determined. Extract was found to obey Beer‐Lambert’s law in the concentration range of 20‐100 μg/ml with regression coefficient (r2) values 0.9995. The regression equations were calculated as y = 0.0097x + 0.0132 for methanol. The developed calibration curve was validated for intra‐day and inter‐day variations as per ICH Q2A guideline and was found to be a stable method.

Abstract: Mesenchymal stem cells (MSC) have emerged as a potential stem cell type for cardiac regeneration after myocardial infarction (MI). Recently, we isolated and characterized mesenchymal stem cells derived from rat fetal heart (fC-MSC), which exhibited potential to differentiate into cardiomyocytes, endothelial cells and smooth muscle cells in vitro. In the present study, we investigated the therapeutic efficacy of intravenously injected fC-MSC in a rat model of MI using multi-pinhole gated SPECT-CT system. fC-MSC were isolated from the hearts of Sprague Dawley (SD) rat fetuses at gestation day 16 and expanded ex vivo. One week after induction of MI, 2×106 fC-MSC labeled with PKH26 dye (n = 6) or saline alone (n = 6) were injected through the tail vein of the rats. Initial in vivo tracking of 99mTc-labeled fC-MSC revealed a focal uptake of cells in the anterior mid-ventricular region of the heart. At 4 weeks of fC-MSC administration, the cells labeled with PKH26 were located in abundance in infarct/peri-infarct region and the fC-MSC treated hearts showed a significant increase in left ventricular ejection fraction and a significant decrease in the end diastolic volume, end systolic volume and left ventricular myo-mass in comparison to the saline treated group. In addition, fC-MSC treated hearts had a significantly better myocardial perfusion and attenuation in the infarct size, in comparison to the saline treated hearts. The engrafted PKH26-fC-MSC expressed cardiac troponin T, endothelial CD31 and smooth muscle sm-MHC, suggesting their differentiation into all major cells of cardiovascular lineage. The fC-MSC treated hearts demonstrated an up-regulation of cardio-protective growth factors, anti-fibrotic and anti-apoptotic molecules, highlighting that the observed left ventricular functional recovery may be due to secretion of paracrine factors by fC-MSC. Taken together, our results suggest that fC-MSC therapy may be a new therapeutic strategy for MI and multi-pinhole gated SPECT-CT system may be a useful tool to evaluate cardiac perfusion, function and cell tracking after stem cell therapy in acute myocardial injury setting.
