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

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

The fields of telepresence and virtual reality have experienced a surge of activity in recent years. The goal of these fields is to place users in an immersive environment that behaves like the real world. To achieve this goal fields require the use of next-generation input devices such as data gloves head-mounted displays and various other immersive peripherals. Posture capture and recognition

The smart meter reference design from Texas Instruments is a comprehensive tool that demonstrates the capabilities of a smart meter. The smart meter board (SMB) performs energy or electricity metering and has the capability of transferring key meter data via wired and wireless sensors to form a simple automatic meter reading (AMR) system. This is a quick start guide to reference design SMB 2.5. Th

This application report discusses some of the key performance results when using LMK0480x/LMK04906to implement hitless switching between reference clocks. Hitless Switching is required in certainapplications such as SONET/SDH/line port cards and routers/switchers in order to minimize thepropagation of phase transients to the clock outputs during reference clock switching. On loss of all vali

C6474 (x2) Power Using Modules

In high-power server applications to meet high-efficiency and green standards some power-supply designers have found it easier to use a phase-shifted, full-bridge converter. This is because the phase-

System designers traditionally power the high-speed data converter in their systems from a low-noise low-dropout linear regulator (LDO) in order to achieve the performance described in the analog-to-digital converter (ADC) data sheet. However LDOs inherently are not very power efficient. Switching regulators on the other hand offer good power efficiency but typically come with higher output no
