Sensorless Speed Controlled Brushless D Drive Using TMS320C242 DSP Controller
Texas InstrumentsThe Brushless DC (BLDC) variable-speed drive is widely used because of its particularly high mechanical power density simplicity and cost effectiveness. A software rotor position generation has been implemented on the DSP Controller family thus saving the mechanical position sensor cost. Based on the non-fed phase back electromotive force measurement this software-computed rotor position is fu

Implementing a Line-Echo Canceller Using the Block Update and NLMS Algorithms on the TMS320C54x DSP
Texas InstrumentsThis document describes the implementation of a line echo canceller (LEC) on the TMS320C54x family of 16-bit fixed-point digital signal processors. Two different implementations of the adaptive transversal echo canceller filter are covered: block update and normalized least-mean square (also called stochastic gradient). Full assembler code is given for both examples.
TMS320C620x/C642x McBSP: UART (Rev. C)
Texas InstrumentsThis document describes how to use the multichannel buffered serial port (McBSP) in the Texas Instruments (TI) TMS320C6000™ (C6000™) digital signal processors (DSP) to interface to a universal asynchronous receiver/transmitter (UART). Descriptions of the hardware configuration and software routines necessary for proper functionality are included.
The McBSP is not capable of support
Power Supply Recommendations for DVD Receivers
Texas InstrumentsSelecting the optimal power supply for a non feed back digital amplifier can be challenging. Music is dynamic, so the power consumption is changing dramatically, from almost zero to maximum within a

Matrix Multiplication With the TMS32010 and TMS32020 ( Contains Scanned Text)
Texas InstrumentsThis report is on matrix multiplication with the TMS32010 and TMS32020. Matrix multiplication is useful in applications such as graphics numerical analysis or high-speed control. Because of the high speed of the multiply/accumulate operations and fast data I/O both processors can multiply in microseconds large matrices with their sizes only limited by the internal data memory. Programs are inc

TPIC6C596 Input Interface Routing
Texas InstrumentsThe TPIC6C596 can be used to switch a variety of low-side loads. Some loads induce transients that can be coupled onto components and traces that can feed back into the control circuits of the TPIC6C596. While the device is designed to minimize interference from external noise the user should plan the board layout and external component placement to help reduce interference in very noisy applicat
Use of Flash Test Pins on TMSx70 F035 Devices (Rev. A)
Texas InstrumentsTexas Instruments TMSx70 microcontrollers built using TI's F035 Flash process have one or two test pins used for advanced testing of the Flash memory. This application report discusses how to utilize these pins when designing circuit boards for one of these processors.
