Application Notes

  • Sensorless Control of a Trapezoidal Brushless DC Motor Using the TMS320C25 DSP
    PDF, 114 Кб, Файл опубликован: 1 июл 1997
    This application report presents the theory and practice of implementing a closed-loop sensorless commutation scheme for a trapezoidal brushless DC motor. The implementation consists of a PC-hosted Texas Instruments (TITM) TMS320C25 digital signal processor (DSP). The TMS320C25 functions as a coprocessor running an algorithm to determine the phase voltage switching points. This solution uses t
  • An Implementation of a Software UART Using the TMS320C25 (Contains Scanned Text)
    PDF, 2.3 Мб, Файл опубликован: 1 мар 1990
    When transmitting to and receiving data from a processing engine such as the TMS320C25 digital signal processor, it is common to encounter problems when interfacing to asynchronous devices. This chapter provides a look at software implementation of a Universal Asynchronous Receiver and Transmitter (UART) which enables communication with asynchronous serial devices with a minimum of external hardwa
  • TMS320 Hardware Applications ( Contains Scanned Text)
    PDF, 7.4 Мб, Файл опубликован: 1 окт 1997
    This report describes the software and circuits necessary to interface to numerous members of the TMS320 family. Specifically, it presents three circuits for interfacing the TLC32040 Analog Interface Circuit to the TMS320 digital signal processors:- TMS32010/E15 Interface to the TLC32040- TMS32020 Interface to the TLC32040- TMS320C17 Interface to the TLC32040 Each circuit section i
  • TMS320C25 Logical Shifts in Parallel With ALU Operations
    PDF, 38 Кб, Файл опубликован: 1 июн 1997
    With an easy trick, a logical right or left shift can be accomplished in parallel with another instruction without disturbing the accumulator, multiplier, or any other part of the ALU. This process is explained with examples to illustrate the details. Specific code commands to implement this process are given.
  • Implementing Field-Oriented Control of AC Motors with the TMS320C25 DSP
    PDF, 426 Кб, Файл опубликован: 1 июл 1997
    The field-oriented theory is the base of a special control method for induction motor drives. With this control method, induction motors can successfully replace expensive DC motors. Induction motors require complex control algorithms, because there is no linear relationship between the stator current and either the torque or the flux. This means that it is difficult to control the speed or the to

  • 8 X 8 Discrete Cosine Transforms on TMS320C25/TMS320C30 (Contains Scanned Text)
    PDF, 1.8 Мб, Файл опубликован: 1 окт 1994
    The Discrete Cosine Transform (DCT) stands apart from other orthogonal transforms because of its favorable comparison to the Karhunen-Loeve Transform (KLT). However, there is no fast algorithm to compute the KLT, which makes the DCT an attractive alternative. This book presents two 8X8 DCT routines and is divided into the following pieces:- The DCT algorithm- Implementation in the TMS320C2
  • Adaptive Filters With TMS320C25 or TMS320C30 ( Contains Scanned Text)
    PDF, 9.5 Мб, Файл опубликован: 1 окт 1994
    Adaptive filtering techniques are necessary considerations when a specific signal output is desired but the coefficients of that filter cannot be determined at the outset. Sometimes this is because of changing line or transmission conditions. An adaptive filter is one which contains coefficients that are updated by an adaptive algorithm to optimize filter response to the desired performance crit
  • Transmission of Still and Moving Images Over Narrowband Channels
    PDF, 57 Кб, Файл опубликован: 1 фев 1994
    Radio networks, such as those used by emergency services or public transportation, transmit across a narrow bandwidth, thus requiring low transmission rates. This document describes the channels and transmission method of these existing networks. Applying complex algorithms to code images allows development of a source codec. This codec uses multiple TMS320C40 32-bit parallel digital signal proces
  • Speaker Independent Speech Recognition on the TMS320C2x and TMS320C5x DSPs
    PDF, 87 Кб, Файл опубликован: 1 окт 1994
    This document presents an implementation of a hidden Markov model (HMM) speech recognition system using the 16-bit fixed-point TMS320C2xx or TMS320C5x digital signal processors (DSPs). It discusses system resource requirements, vocal flexibility and future enhancements to this system. The application is verified using a TMS320C53 DSP platform.
  • A DSP GMSK Modem for Mobitex and Other Wireless Infrastructures
    PDF, 94 Кб, Файл опубликован: 1 окт 1994
    Mobitex, a packetized wireless 900MHz wide area network (WAN) allows mobile/portable subscribers to transfer data, including e-mail, through the growing national and international network infrastructures. This document describes Mobitex DSP modems, their characteristics, and modulator design. The GMSK demodulator design is also presented.
  • Automated Dialing of Cellular Telephones Using Speech Recognition
    PDF, 53 Кб, Файл опубликован: 1 окт 1994
    Automated speech recognition (ASR) technology has been a bedfellow of cellular phone technology for many years. The benefits of combining the two technologies are obvious; the less time and focus a driver gives to placing a call, the more attentive he is to operating a vehicle. This document explains ASR technology implemented on a TMS320C2x DSP and shows the accuracy of this design.
  • Design of Active Noise Control Systems With the TMS320 Family
    PDF, 646 Кб, Файл опубликован: 1 июн 1996
    An active noise control (ANC) system based on adaptive filter theory was developed in the 1980s; however, only with the recent introduction of powerful but inexpensive digital signal processor (DSP) hardware, such as the TMS320 family, has the technology become practical. The specialized DSPs were designed for real-time numerical processing of digitized signals. These devices have enabled the

  • Minimizing Quantization Effects Using the TMS320 DSP Family
    PDF, 268 Кб, Файл опубликован: 1 июл 1994
    Due to its discrete nature DSPs represent variables and performs arithmetic functions with a finite word length. This produces three effects: the selection of filter transfer functions is quantized with filter poles and zeros existing only at specific locations in the z plane; the input is quantized; and noise is introduced from DSP multiplication and division operations. This document shows how
