The ADS7843 ADS7845 and the new ADS7846 converters all are designed for specific touch screen applications. Applications using these devices can benefit greatly from the tips presented in this application bulletin. Most of the examples discuss the ADS7843 but the techniques shown are applicable to all of the devices.

In many DSP applications there is a need to copy code and/or data from one location to another at boot. C6000 DSPs offer three types of boot configurations: no boot process ROM boot process and host boot process. The most commonly selected boot configuration is the ROM boot process. When ROM boot is selected as the boot configuration 1K byte (on C621x/C671x/C64x™) of code will automatica

A stack overflow in an embedded DSP application generally produces a catastrophic software crash due to data corruption lost return addresses or both. Traditional off-line approaches to sizing a stack during development such as filling with a know value or estimating based on code content are not 100% reliable. Therefore programmers often feel compelled to reserve larger stack sizes than are

2.5 Gbps LVDS 4 x 4 Crosspoint Switch

This technical brief provides an overview of communication receiver sensitivity. One of the most important parameters in determining the overall performance of a communication system, receiver sensiti

This application bulletin covers the DDC112’s test mode. It elaborates on the explanation given in the data sheet and is written with the purpose of helping you use the test mode to its fullest capability. It does assume a basic understanding of the DDC112’s operation. For a good introduction to the DDC112, see the DDC112’s data sheet.

The organization of this application bulletin is as follows: First, an overview presents the basic operation of the test mode. Next are explanations of single packet and multiple packet test signals. Noise and linearity performance of the test mode are then covered followed by some special considerations for using the test mode. Finally, a program for investigating test mode performance is discussed with the listing for the program given afterwards.

Switching voltage regulators represented by the TL497 can achieve high-efficiency power conversion at large input/output voltage differentials. The TL497A eliminates complex circuit designs previously required and provides greater efficiency than systems using series pass regulators. The principle of operation is discussed and practical design exercises for step-down step-up and inverting reg

In most wireless communications systems convolutional coding is the preferred method of error-correction coding to overcome transmission distortions. This report outlines the theory of convolutional coding and decoding and explains the programming techniques for Viterbi decoding in the Texas Instruments TMS320C55x™ generation of digital signal processors (DSPs). The same basic methods deco

This report presents algorithms and code implementing floating-point addition subtraction multiplication and division with the TMS320. The support of floating-point operations by the TI processors has made possible some applications such as the implementation of the CCITT Adaptive Differential Pulse Code Modulation (ADPCM) algorithm and image/graphics operations.

Ultrasonic sensing utilizing Time Of Flight (TOF) measurement techniques are used in liquid level and fluid identification sensing in the automotive consumer and medical markets. Ultrasonic (TOF) sensing can yield high accuracy and high reliability with low-power consumption for all of these markets. In order to achieve the best cost-to-performance combination care must be ta
