This application report demonstrates how to build a compressed ROM file system (cramfs) file system image and add support for cramfs in the Linux kernel. The goal is to build a small file system that can be placed in Flash memory. Since cramfs is a read-only file system with limited size it is mostly useful in embedded devices where there is a limited amount of storage and there is no need to wri

The DSP Hardware Designer's Resource Guide is organized by development flow and functional areas to make your design effort as seamless as possible. Topics covered include getting started, board desig

The TPS2384 power manager controls four ports in a PoE system. This application report discusses the proper termination of unused port pins in order to ensure correct device operation.

DC motor speed is often regulated with a closed-loop speed controller using tachometer feedback. It is possible however to control dc motor speed without tachometer feedback.

Designing Switching Voltage Regulators With the TL494

This application report describes differences between the Texas Instruments TMS320x2833x/2823x and the TMS320x2834x Delfino? devices to assist in application migration. While the main focus of this do

The TLV1549, 10-bit serial-out A/ D converter operates with a 3.3-V (+/- 0.3 V) single supply. The device uses a switched-capacitor successive approximation method to perform the A/D conversion in a m

This application report is intended to help users of the TRF7970A high-frequency RFID/NFC reader IC understand the differences between it and the TRF7960 IC. Understanding these differences in detail and applying this knowledge to application-specific requirements can assist in development efforts.

AN-466 Improving the Performance of a High Speed PBX Backplane

LM2902-Q1, LM2904-Q1 Low-Level Output Voltage vs. Sinking Current of a Bipolar Output Amplifier

The bq27505 battery fuel gauge has many data flash constants that can configure the device with various, different options for most features. The data flash of the bq27505 is split into sections, whic

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

Application Note 982 COP888GW Features and Applications

TVP5151 VBI Quick Start

This application report provides a comprehensive guide into the design of the hardware interface between the Texas Instruments (TI)(tm) TMS320C54x digital signal processor (DSP) and the TMS626812A 2MX8 synchronous dynamic random-access memory (SDRAM) using field programmable gate arrays (FPGA). A test algorithm is also written in assembly to test the hardware design and the SDRAM. This design ca

This document specifies the ELF-based Application Binary Interface (ABI) for the C6000 Family of processors from Texas Instruments. The ABI is a broad standard that specifies the low-level interface between tools programs and program components.

You know it's going to be one of those days when you see the printed version of an article you wrote and realize that you have made an error in the presentation of your ideas. This is what happened to me as I read Use High Speed S/H to Improve Sampling ADC Performance (Design Update Vol.1 No.1). This article will rectify the situation and further illuminate some important performance aspe
