This application report describes how to develop a real-time system for producing lung sound spectrographs and other analyses using the Texas Instruments (TITM) TMS320C30 (C30) digital signal processor (DSP). The C30 floating point processor, hosted by a PC with a 486 DX2 processor (or better) is written entirely in the C language. With this real time system, analog input can be captured direct...

Evaluation and Guidance in Processor Architecture Selection for DSP

General-purpose processors have utilized complex and energy inefficient techniques to accelerate performance. In embedded DSP designs, power constraints have precluded general-purpose microarchitectural techniques. Rather than minimize average execution time, embedded DSP processors require the worst-case execution time to be minimized. Subsequently, Very Long Instruction Word (VLIW) processors...

Modern digital signal processing (DSP) applications call for computationally intensive data processing at very high data rates. In order to meet the high-performance/lowcost constraints, the state-of-the-art video processor should be a programmable design which performs various tasks in video applications without sacrificing the computational power and the manufacturing cost in exchange for suc...

Java is for sure the most popular programming language today. Its popularity is based on the portability of the code and on the elegant programming framework provided by the language: built in garbage collection and multi-threaded support, easy Internet application development through socket streams, and last but not least familiar syntax. Even if a lot of work has already been done related to ...

With the advent of personal computer, smart phones, gaming and other multimedia devices, the demand for DSP processors in semiconductor industry and modern life is ever increasing. Traditional DSP processors which are special purpose (custom logic) logic , added to essentially general purpose processors, no longer tends to meet the ever increasing demand for processing power. Today FPGAs have b...

IDE for DSP Virtuoso v. 4.2 is an integrated development environment for the design of multi-processor embedded DSP networks, such as radar, sonar, and highend image processing. It includes the Virtuoso RTOS, a project manager, a multi-threaded asynchronous network host server, and a suite of graphical analysis and debugging tools, as well as plug-ins to Code Composer Studio and Visual DSP. The...

This paper describes the details of bit-exact and real-time implementation of ITU-T G.729 annex A speech codec on a fixed-point DSP processor. The DSP used for implementation is Texas Instruments’ high performance TMS320C6211. In addition to developed new DSPs with lower power consumption at higher clock speeds, the software development tools and compilers have also improved. Thus, the optimiza...
