ECE345, Visual-to-Audio Electronic Travel Aid Code for TM320C54x (v2a.asm) download This project involves the design and implementation of a audio synthesis device that converts moving images into audio signals. The system is built on a TM320C54x DSP with interface to an IMAQ camera module via the serial port on a PC. Brief description: A LabVIEW VI acquires an image from the IMAQ camera module. It quantizes the image into a 5x5, 3-bit image, and sends the data to the TM320C54x DSP via a serial port. The TM320C54x DSP constructs a 64-tap FIR by combining a series of 64-tap head related transfer functions (HRTF) according to the incoming data, and then filters an input audio signal with this FIR filter, in effect creating a correspondence between the filtered signal and the original image.

MPI stands for the Message Passing Interface. Written by the MPI Forum (a large committee comprising of a cross-section between industry and research representatives), MPI is a standardized API typically used for parallel and/or distributed computing. The MPI standard is comprised of 2 documents: MPI-1 (published in 1994) and MPI-2 (published in 1996). MPI-2 is, for the most part, additions and extensions to the original MPI-1 specification. The MPI-1 and MPI-2 documents can be downloaded from the official MPI Forum web site: http://www.mpi-forum.org/. Open MPI is an open source, freely available implementation of both the MPI-1 and MPI-2 documents. The Open MPI software achieves high performance the Open MPI project is quite receptive to community input.

These are P-Channel enhancement mode silicon gate power fi eld effect transistors. They are advanced power MOSFETs designed, tested, and guaranteed to withstand a specifi ed level of energy in the breakdown avalanche mode of operation. All of these power MOSFETs are designed for applications such as switching regulators, switching converters, motor drivers, relay drivers and drivers for other high-power switching devices. The high input impedance allows these types to be operated directly from integrated circuits.

The SP486 and SP487 are low–power quad differential line drivers meeting RS-485 and RS-422 standards. The SP486 features a common driver enable control the SP487 provides independent driver enable controls for each pair of drivers. Both feature tri–state outputs and wide common–mode input range. Both are available in 16–pin plastic DIP and SOIC packages.

In this project we analyze and design the minimum mean-square error (MMSE) multiuser receiver for uniformly quantized synchronous code division multiple access (CDMA) signals in additive white Gaussian noise (AWGN) channels.This project is mainly based on the representation of uniform quantizer by gain plus additive noise model. Based on this model, we derive the weight vector and the output signal-to-interference ratio (SIR) of the MMSE receiver. The effects of quantization on the MMSE receiver performance is characterized in a single parameter named 鈥漞quivalent noise variance鈥? The optimal quantizer stepsize which maximizes the MMSE receiver output SNR is also determined.

-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. Mutual Information is the similarity measure used in this case for optimizing the two images. This method requires estimating joint histogram of the two images. The fusion of images is the process of combining two or more images into a single image retaining important features from each. The Discrete Wavelet Transform (DWT) has become an attractive tool for fusing multimodal images. In this work it has been used to segment the features of the input images to produce a region map. Features of each region are calculated and a region based approach is used to fuse the images in the wavelet domain.
