Data acquisition made simpler

Article Abstract:

Software vendors are delivering products to meet users' demands for data acquisition and processing applications that run on both workstations and high-end microcomputers. These vendors are offering packages that are much closer to being platform independent than they were a year ago, and they are building device-driver libraries that address more instrumentation across more computer platforms. Another trend in data acquisition programs is the inclusion of an icon graphical user interface (GUI) to help engineers control their work. One type of icon software allows users to enter performance preferences in predefined table-based icons; another lets users define the icon's function themselves and link it to other icons hierarchically. Some of the most popular data analysis tools include Scientific Software Tools Inc's DriverLINX/VB, National Instruments Corp's LabVIEW 2.5 and Neural Network Toolbox from The Mathworks Inc. A directory of products and vendors is presented.

Tools for embedding DSP

Article Abstract:

Development tool software packages are becoming available for developing systems with multiple digital signal processor (DSP) chips. Such tools address software coding, algorithm development and debugging. Algorithm design is at the heart of a DSP system's functionality, since the algorithm describes the mathematical procedures the DSP uses to operate on the input to generate the output. DSP algorithm development software should offer code generation options, the ability to simulate the DSP portion of the embedded system, a flexible graphics interface, the abilities to represent the system as a macro and accept user-supplied data as input, and access to standard DSP functions. Two such packages include DSP Development Corp's DADiSP/PRO-32 and Hyperception's Block Diagram. A directory of vendors and products is presented.
