    This is GPS Acquisition..by Matlab, this file performs cold start acquisition on the collected "data". It searches for GPS signals of all satellites, which are listed in field "acqSatelliteList" in the settings structure. Function saves code phase and frequency of the detected signals in the "acqResults" structure.

  • Enhanced version of the Serial Peripheral Interface available on Motorola s MC68HC11 family of CPUs.

    Enhanced version of the Serial Peripheral Interface available on Motorola s MC68HC11 family of CPUs.Enhancements include a wider supported operating frequency range, 4deep read and write fifos, and programmable transfer count dependent interrupt generation. As with the SPI found in MC68HC11 processors the core features programmable clock phase [CPHA] and clock polarity [CPOL]. The core features an 8bit wishbone interface. Very simple, very small.

  • The Hilbert Transform is an important component in communication systems, e.g. for single sideband m

    The Hilbert Transform is an important component in communication systems, e.g. for single sideband modulation/demodulation, amplitude and phase detection, etc. It can be formulated as filtering operation which makes it possible to approximate the Hilbert Transform with a digital filter. Due to the non-causal and infinite impulse response of that filter, it is not that easy to get a good approximation with low hardware resource usage. Therefore, different filters with different complexities have been implemented. The detailed discussion can be found in "Digital Hilbert Transformers or FPGA-based Phase-Locked Loops" (http://ieeexplore.ieee.org/xpl/freeabs_all.jsp?arnumber=4629940). The design is fully pipelined for maximum throughput.

    The emphasis of this book is on real-time application of Synopsys tools, used to combat various problems seen at VDSM geometries. Readers will be exposed to an effective design methodology for handling complex, submicron ASIC designs. Significance is placed on HDL coding styles, synthesis and optimization, dynamic simulation, formal verification, DFT scan insertion, links to layout, physical synthesis, and static timing analysis. At each step, problems related to each phase of the design flow are identified, with solutions and work-around described in detail. In addition, crucial issues related to layout, which includes clock tree synthesis and back-end integration (links to layout) are also discussed at length. Furthermore, the book contains in-depth discussions on the basics of Synopsys technology libraries and HDL coding styles, targeted towards optimal synthesis solution.

  • G UILLAIN-BARRéSYNDROME(GBS)is an uncommon disorder,but one whose impact is far out of proportion

    G UILLAIN-BARRéSYNDROME(GBS)is an uncommon disorder,but one whose impact is far out of proportion to its incidence.Despite a usually good prognosis,GBS is a particularly frightening and often life- altering experience for those diagnosed with the disorder.Many patients are acutely aware of the rapid loss of control of their muscular function, including vital functions such as breathing and swallowing,and fre- quently feel that they are dying.The experience is almost as unnerving for the families of affected individuals.During the acute phase of the ill- ness GBS patients experience the indignity of helplessness in addition to their fear of death or permanent disability.Prolonged disability is com- mon and some permanent residual effects are becoming increasingly recognized.It has been our experience in meeting patients at support groups,that individuals who have been affected by GBS have a great desire for a better understanding of the disorder,even years after the acute experience.

  • This application note considers the design of frequency- selective filters, which modify the freque

    This application note considers the design of frequency- selective filters, which modify the frequency content and phase of input signals according to some specification. Two classes of frequency-selective digital filters are considered: infinite impulse response (IIR) and finite impulse response (FIR) filters. The design process consists of determining the coefficients of the IIR or FIR filters, which results in the desired magnitude and phase response being closely approximated.
