The digital signal processor (DSP) industry has been growing steadily over the past few years due to strong demands for digital signal processors in a variety of applications. Among these applications, wireless communication accounts for more than two-thirds of the DSP market today. The Selectable Mode Vocoder (SMV) is a third generation (3G) speech coding technology that provides significant c...

Title of dissertation: DATAFLOW INTEGRATION AND SIMULATION TECHNIQUES FOR DSP SYSTEM DESIGN TOOLS Chia-Jui Hsu Doctor of Philosophy, 2007 Dissertation directed by: Professor Shuvra S. Bhattacharyya Department of Electrical and Computer Engineering System-level modeling, simulation, and synthesis using dataflow models of computation are widespread in electronic design automation (EDA) tools for ...

DSP software development has been tied down by extreme computational requirements. Furthermore, the DSP development tools available today are less advanced than in other embedded software design. This has lead to DSP software architectures that have not taken into account future expansion needs. Therefore, DSP software architectures have been inherently closed. Now, as system complexity increas...

It has been shown that a framework composed of digital signal processing (DSP) elements can be used to simulate and study Freeman’s model of the biologically realistic olfactory cortex. In this paper, based on impulse invariant transformation, a DSP environment has been developed corresponding to the original continuous-time dynamical system. The performance of the DSP system is quantitatively ...

J-DSP-C is a java-based object-oriented programming environment that was developed at Arizona State University for use in control systems education. This environment enables the simulation of dynamical systems on-line from any computer system equipped with an Internet browser. The J-DSP-C features are primarily aimed to provide an on-line laboratory experience to distance learning students. Com...

There is an industry trend in the development of single board computers based on DSPmicroprocessors. These microprocessors have specialized instruction sets that are optimized for DSP operations and architectures that are tuned for DSP program control. They also provide the structure necessary to support operating system functions. They are being used to supplement processing in PC and workstat...

This paper describes the MetaCore system which is an ASIP(Application-Speci c Instruction set Processor) development system targeted for DSP applications. The goal of MetaCore system is to o er an e cient design methodology meeting speci cations given as a combination of performance, cost and design turnaround time. MetaCore system consists of two major design stages: design exploration and des...

Combining the daily operations of the utilities, the latest computer technology and the professional technology of distribution network planning, a practical GIS (Geographical Information System) based computer decision-making support system with eight sub systems for urban power distribution network planning is introduced. The models and functions of the system are described. This system has b...
