Accessing Status and Control Fields and I/O Ports in the TMS320Cxx HLL Debugger
Texas InstrumentsThe ARP along with the data page pointer (DP) carry bit (C) and a variety of other fields are located in the status registers of the 'C5x. These registers are displayed in the CPU register window of the HLL debugger but it is inconvenient to observe the value of any one individual field.The HLL debugger has two features that can help display the desired field(s) in an easy-to-observe manner.

Controlling the ADS8342 with TMS320 Series DSP's
Texas InstrumentsThe ADS8342 16-bit, bipolar input, parallel output analog-to-digital converter has a number of features that allow for an easy interface to many of the TMS320? DSP family of digital signal processors
Texas Instruments GTLP Frequently Asked Questions
Texas InstrumentsUsing a question-and-answer format, advantages of TI?s GTLP devices, particularly for backplane applications, are presented, as well as differences between GTLP and GTL/LVDS devices. Applicable topics
Using the ADS7841 and ADS7844 with 15-Clock Cycles
Texas InstrumentsThis application report presents an analysis on the use of the 15-clock cycle method of operation for the ADS7841 and ADS7844 described in their respective data sheets. The advent of commercially available processors such as the TMS470 no longer restricts users from implementing the 15-clock method with simple microprocessors. This method however does present some challenges to the software inte
Minimizing Quantization Effects Using the TMS320 DSP Family
Texas InstrumentsDue to its discrete nature DSPs represent variables and performs arithmetic functions with a finite word length. This produces three effects: the selection of filter transfer functions is quantized with filter poles and zeros existing only at specific locations in the z plane; the input is quantized; and noise is introduced from DSP multiplication and division operations. This document shows how

Reducing System Power Requirements
Texas InstrumentsWith the ever-growing need for battery-operated systems the need for low-power designs has increased significantly in recent years. These low-power applications have expanded to include high-speed DSP designs. It is necessary to design with high-speed devices while maintaining an overall power reduction. This document discusses a number of ways to reduce your system power ranging from the use of

10MHz Analog Multiplier Carries Output Amp Breaks Bandwidth Barrier
Texas InstrumentsWith the introduction of the MPY634 multipliers wideband analog multiplication need no longer be a multicap affair or imply performance compromises. Along with its 10MHz small-signal bandwidth the four-quadrant chip has a laser-trimmed DC accuracy of 0.25% and adjustable scale factor and the ability to drive loads down to 2kΩ.
