This paper describes the implementation of the V.32bis decoding algorithm on the Texas Instruments (TI) TMS320C62xx digital signal processor (DSP). The V.32bis Viterbi decoder algorithm is based on a soft-decision maximum-likelihood decoding technique. (Details on the theory behind this algorithm are described in the TI publication DSP Solutions for Telephony and Data/Facsimile Modems literature

This application provides an overview of the UCCx81-ADJ, UCCx82-ADJ, UCCx83-ADJ, UCCx84-ADJ, and UCcx85-ADJ devices.

This document describes an IEEE 1149.1-based test integrated circuit (IC) referred to as a digital bus monitor (DBM) which emulates the functions of logic and signature test instruments. The DBM provides an embedded method of monitoring circuits at speed either on the board or at the multi-chip module level. A basic understanding of the IEEE 1149.1 standard is assumed.

This application report is intended as a guide for using an analog multiplexer to multiplex several input signals to a single high-resolution high-speed SAR analog-to-digital converter (ADC). The ADC and the multiplexer used were the ADS8411 and the TS5A3159/3359 respectively. This document discusses the important parameters of a multiplexer and defines a few important measurements for evaluatin

An ultrasound system employs a multichannel phased array of acoustic elements to form an image. Previous implementation of this function has used bipolar technology. 0.5u CMOS technology has the advantage of lowering the cost and increasing functionality compared to using bipolar technology.

This application report describes how to interface the DAC7631 digital-to-analog converter (DAC) to the MSP430F449 mixed signal microcontroller.

Multiplication of analog signals has long been one of the most important nonlinear functions of analog circuit technology. Many signal sources however such as CCD sensors pin diodes or antennas deliver weak oscillating and simultaneously wide-band signals. But now a new multiplication method is available. Used as a wide-bandwidth Automatic Gain Control (AGC) application circuit the integra

ATL431 ATL431 Application Note

As real-time digital signal processing (DSP) systems become more complicated with multiple threads of execution and faster DSPs software development and debugging becomes more complicated. An MP3 player is a good example of a multi-threaded system that executes not only DSP-type (data) threads such as MP3 decoding sample rate conversion and graphic equalization but it also runs typical ?host/c
