Application Notes

The parallel architecture of the 32-bit multiprocessor TMS320C80 ('C80) digital signal processor (DSP) offers incredible horsepower that is underutilized without a high-speed memory interface. The 'C80 contains a built-in interface for SDRAM. This document discusses the interface between the 'C80 and the TMS626802-10 SDRAM the SDRAM pins and the SDRAM operation. A timing evaluation of the inter

TMS320C6000 C Compiler: C Implementation of Intrinsics

Texas Instruments

The first optimization step that you can perform on C source code for the TMS320C62xx is to use intrinsic operators. Intrinsics are used like functions and produce assembly language statements that would otherwise be inexpressible in C. The problem is that once you have performed the first optimization step your C source code is no longer ANSI C compatible. The code proposed within this appli

A description of the model is provided along with correlation to actualdevice behavior.

Extending Battery Life with the TPS61040 White Light LED Driver

Texas Instruments

This application note describes how to extend the battery life of a circuit that uses Texas Instrument's TPS61040 low power dc-dc boost converter for driving white light LEDs. Power loss in the current sense resistor is discussed and a method for reducing this loss is presented. Design equations are given for calculating the proper resistor values for a white light LED driver that includes prov
