This document descibes the process used to develop loop partitioning for the Texas Instruments (TI)(tm) TMS320C6x digital signal processor (DSP). The 'C6x code generation tools go through five basic phases when scheduling a loop. At each of these stages there is a set of heuristics which try to make intelligent decisions where multiple options exist. This document focuses on the third stage parti

This application report describes the set-up and expected performance when using the CC2640 in external regulator mode together with the TPS62740. Although this application report focuses on the CC2640 and Bluetooth® Smart applications the solutions provided are also applicable for the entire CC26xx family and its supported protocols. Note that waveforms and power consumption measurement r

This reference design is intended to help designers wishing to use two of the new Virtex-6™ LX240 FPGA along with DDR memory and other optional circuitry in their designs. It provides nine rails of lower voltage with an input of 12 volts. The use of PTH T2 modules provides a high-performance solution for good transient response and tight regulation while conserving valuable board space.

The user has a variety of EEPROMs to select for use with the TFP501. This report describes some considerations for selecting an EEPROM for use with the TFP501. Examination of the I2C activity of the TFP501 can provide an understanding of the power on requirements for the device in test. Comparison of EEPROM activity to known results can aid in diagnosis of board problems.

This application report presents a method for interfacing the ADS8361 16-bit SAR analog-to-digital converter to the TMS320C6711 DSP using McBSP1. The software developed reads 1024 samples continuously from the ADS8361. In an effort to reduce development time the source code for this application note can be found on the Texas Instruments web site at http://www.ti.com. Search for document number

The ULN2003A has long been a popular device used for driving high-current peripheral circuits from microcontroller and control logic output signals. The ULN2003A consists of seven Darlington bipolar transistors which sink current from the output to ground when a high logic signal is placed on the input. Because the ULN2003A is based on bipolar Darlington transistor topology, it dissipates a considerable amount of power even when it sinks small output currents.

The TPL7407L is a new peripheral driver that uses an N-channel MOSFET transistor on the output instead of the bipolar Darlington pair. Because of the NMOS output, the TPL7407L can sink more current to ground while dissipating less power and generating less heat which makes it an overall improved device compared to the ULN2003A. This application note explains how the CMOS technology in the TPL7407L improves power dissipation and thermal performance compared to the ULN2003A, including a 50% reduction in power consumption in typical use cases.

Reference Framework 5 (RF5) for eXpressDSP Software is provided as starterware for developing applications that use DSP/BIOS and the TMS320 DSP Algorithm Standard (also known as XDAIS). The XDAIS standard has introduced DMA specifications on how algorithms should use the DMA resources and it is possible to incorporate an algorithm adhering to these specifications into RF5.
