The Cell is a heterogeneous multicore processor that has attracted much attention in the HPC community. The bulk of the computational workload on the Cell processor is carried by eight co-processors called SPEs. The SPEs are connected to each other and to main memory by a high speed bus called the Element Interconnect Bus (EIB), which is capable of 204.8(More)
Simultaneous multithreading (SMT) provides a technique to improve resource utilization by sharing key dat-apath components among multiple independent threads. When critical resources are shared by multiple threads, effective use of these resources proves to be the most important factor in fully exploiting the system potential. Allowing any of the threads to(More)
—The main drawback of the OFDM is its high peak to average power ratio(PAPR).There are several PAPR reduction techniques. Among the various PAPR reduction techniques, companding transform is attractive for its simplicity and effectiveness. This paper proposes a new companding algorithm. The proposed algorithm offers an improved bit error rate and minimized(More)
In this paper an effective design and implementation of the fast Fourier transform (FFT) by the paired transforms is presented and compared with the existent radix-2 algorithm. A block level design of the fast transform methods is implemented and tested in this research work. Discussed is a possibility of reducing the arithmetic computations, hardware(More)
PURPOSE To screen for sequence variations in the IDO gene that encodes indoleamine 2, 3- dioxygenase (IDO), the first rate limiting enzyme involved in the tryptophan catabolism which results in the production of UV filters playing a role in the maintenance of lens transparency. METHODS We conducted a case-control study to screen for sequence changes in(More)
The main aim for the oral delivery of most of the drugs as potential therapeutic agents is their extensive presystemic metabolism, instability in acidic environment resulting into inadequate and erratic oral absorption. Parenteral route of administration is the only established route that overcomes all these drawbacks associated with these orally(More)
