    In term project, we will take the baseline JPEG codec in ARM-based platform system as an example to practice the design flow in SoC. We divide the project into three parts, and the goal of each part is described as follow. Part I: Design a baseline JPEG software codec in C/C++ and port it to ARM core,(ARM7TDMI, ARM720T, or ARM922T.) Part II: Make use of virtual prototype to integrate/verify the hardware and software. Part III: Verify your soft IP in target environment.

  • cordic methods describe essentially the same algorithm that with suitably chosen inputs can be used

    cordic methods describe essentially the same algorithm that with suitably chosen inputs can be used to calculate a whole range of scientific functions including sin, cos, tan, arctan, arcsin, arccos, sinh, cosh, tanh, arctanh, log, exp, square root and even multiply and divide. the method dates back to volder [1959], and due to its versatility and compactness, it made possible the microcoding of the hp35 pocket scientific calculator in 1972. here is some code to illustrate the techniques. ive split the methods into three parts linear, circular and hyperbolic. in the hp35 microcode these would be unified into one function (for space reasons). because the linear mode can perform multiply and divide, you only need add/subtract and shift to complete the implementation. you can select in the code whether to do the multiples and divides also by cordic means. other multiplies and divides are all powers of 2 (these dont count). to eliminate these too, would involve ieee hackery.

  • Many CAD users dismiss schematic capture as a necessary evil in the process of creating PCB layout

    Many CAD users dismiss schematic capture as a necessary evil in the process of creating PCB layout but we have always disputed this point of view. With PCB layout now offering automation of both component placement and track routing, getting the design into the computer can often be the most time consuming element of the exercise. And if you use circuit simulation to develop your ideas, you are going to spend even more time working on the schematic.

    We analyze, both analytically and numerically, the effectiveness of cloaking an infinite cylinder from observations by electromagnetic waves in three dimensions. We show that, as truncated approximations of the ideal permittivity and permeability tensors tend towards the singular ideal cloaking fields, so that the anisotropy ratio tends to infinity, the D and B fields blow up near the cloaking surface. Since the metamaterials used to implement cloaking are based on effective medium theory, the resulting large variation in D and B will pose a challenge to the suitability of the field averaged characterization of " and 碌. We also consider cloaking with and without the SHS (softand- hard surface) lining, shown in [6] to be theoretically necessary for cloaking in the cylindrical geometry. We demonstrate numerically that cloaking is significantly improved by the SHS lining, with both the far field of the scattered wave significantly reduced and the blow up of D and B prevented.

    In the bank all the activities are being done manually .As the bank widens its services & it finds difficult to manage its operations manually and hence this leads to the automation of some of its operations. Banking Information system is a windows based applications. This project mainly deals with managing there types of account such as Saving Account, Current Account and Recurring Deposits . In this project bank is seeking to manage these account through computer based system. Tasks involved in this project are opening the user accounts , recording the account holders transactions , modify, the user records and generating the reports . This project is having three module: ] 1. Bank Master Module 2. Transaction Module 3. Reports module

  • The existence of numerous imaging modalities makes it possible to present different data present in

    The existence of numerous imaging modalities makes it possible to present different data present in different modalities together thus forming multimodal images. Component images forming multimodal images should be aligned, or registered so that all the data, coming from the different modalities, are displayed in proper locations. The term image registration is most commonly used to denote the process of alignment of images , that is of transforming them to the common coordinate system. This is done by optimizing a similarity measure between the two images. A widely used measure is Mutual Information (MI). This method requires estimating joint histogram of the two images. Experiments are presented that demonstrate the approach. The technique is intensity-based rather than feature-based. As a comparative assessment the performance based on normalized mutual information and cross correlation as metric have also been presented.
