Memory Alias Disambiguation on the TMS320C6000
Texas InstrumentsThis application report is a tutorial and practical treatment on the problem of memory alias disambiguation on the TMS320C6000 (tm) DSP. If you write C6000 linear assembly or hand-coded assembly you will gain direct practical knowledge and advice on how to use the tools to handle this problem. If you write in C/C++ you will gain insight into how the compiler handles this problem as well as some
Using TI's DLMS COSEM Library
Texas InstrumentsThis application report describes in detail the usage of DLMS COSEM library developed by Texas Instruments for customers who use TI’s microcontrollers in metering applications. The library is provided as object coded with a configuration file for ease of use. The library can be obtained by contacting the regional sales and marketing offices. The customer will have to sign an SLA before getting access to the library.

Add DTMF Generation and Decoding to DSP-uP Designs ( Contains Scanned Text)
Texas InstrumentsBecause of the programmability of the digital signal processor the TMS32010 can also be programmed to handle Dual-Tone MultiFrequency (DTMF) encoding and decoding over telephone lines. For a system already performing digital signal processing functions using the TMS320 this DTMF capability may be obtained at no additional hardware cost. This report is a reprinted article from Electronic Design N
Using the ADS8382 With the TMS320C6713 DSP
Texas InstrumentsThis application report presents a solution to interfacing the ADS8382 18-bit 600-KSPS serial interface converter to the TMS320C6713 DSP. The hardware solution is made up of existing hardware: the ADS8382EVM 'C6713 DSK and 5-6K Interface Board. The software demonstrates how to use an EDMA and Timer peripheral to collect data at 598 kHz. Discussed also are some of the key points to remember when
Handbook of Operational Amplifier Active RC Networks (Rev. A)
Texas InstrumentsWhile in the process of reviewing Texas Instruments applications notes including those from the recently acquired Burr-Brown ? I uncovered a couple of treasures this handbook on active RC networks and one on op amp applications. These old publications from 1966 and 1963 respectively are some of the finest works on op amp theory that I have ever seen. Nevertheless they contain some material
The TMS320C54x DSP HPI and PC Parallel Port Interface
Texas InstrumentsThe TMS320C5x and TMS320C54x contain a host port interface (HPI) functional block that interfaces to a microcontroller unit without external hardware. This document describes the hardware considerations for the interface design. The appendix provides the TMS320C5x assembler source code for the kernel software and software bootload sequence.
