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 reference design is intended for users designing with the TMS320C6742 TMS320C6746 TMS320C6748 or OMAP-L132/L138 processor. Using sequenced power supplies this reference design describes a system having a 3.3-V input voltage and a high-efficiency dc/dc converter with integrated FETs for a small simple design.Sequenced power supply architectures are becoming commonplace in high-performan

SCANSTA101 Quick Reference Guide

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

Hardware Design Guide for KeyStone Devices

When a CD is inserted the Internet Audio CD (IACD) system reads all of the file information ? structure size and attributes ? on the CD and stores this information to memory in a data structure. You can use this information to implement all of the functions related to any files. However since the file system structure is included in the system core code a system developer cannot handle this
