This report presents algorithm and code implementing floating-point addition subtraction multiplication and division with the TMS320. The support of floating-point operations by the TI processors has made possible some applications such as implementation of the CCITT Adaptive Differential Pulse Code Modulation (ADPCM) algorithm and image/graphics operations.
Ground loops can be introduced when different components in audio systems are connected with standardaudio cables and these loops can cause annoying interference. In many cases the interference can bereduced significantly with a ground loop break (GLB) circuit including a low-value resistor and differentialamplifiers. This paper explains this approach and how to design a GLB circuit.
This report describes the coding requirements techniques and decisions whichmust be made to utilize the TMS320C80 DSP as an integrated services digitalnetwork (ISDN) video-system manager and provides an overview on how theprocessor handles video signal in the ISDN narrow-band format in conformancewith the International Telecommunications Union (ITU)?T H.261 Recommendation.
Increasing performance requirements of personal computers that necessitate a larger number of SDRAMs and DIMMs can be met by an FET-switch muliplexer. Four devices for memory interleaving for the 440BX and other core-logic chipsetsincorporate internal pulldown resistors damping resistors and make-before-break features that increase speed while maintaining minimal simultaneous-switching noise.
Today?s communications equipment requires DSPs to perform complicated algorithms in a limited amount of time. One such algorithm is the equalizer in a digital receiver. The equalizer removes distortions caused by the communications link between the transmit and receive antennae. This document discusses implementing an equalizer for the IS-54 standard on the fixed point TMS320C5x DSP. Background fo
Decompensated operational amplifiers have improved noise slew rate harmonic distortion etc. but required external compensation for stable operation. This report shows how to compensate such an amplifier and achieve the performance enchancement it provides in a unity-gain configuration.The THS4011 and THS4021 operational amplifiers are used to illustrate the superior performance mentioned a
Advances in digital signal processors (DSPs) are driving both high-computational performance and power efficiency into ever increasing application areas. The medical diagnostic ultrasound industry can
There are three General Purpose (GP) Timers in the Event Manager of the 'C240. These timers can be used as independant time bases in applications such as:? generation of sampling period in a control system? providing time base for quadrature encoder sensor signal processing in a motor control system? providing time base for the operation of Full and Simple Compare Units and associated
This document describes the Texas Instruments (TI?) TRF3520 evaluation module (EVM) board and associated EVM software, which allows the evaluation and the demonstration of the TRF3520 GSM RF Modulator
This application report provides the Electromagnetic Compatibility (EMC) performance comparison forradiated and conducted emissions between devices in the same high-frequency buck converter family.TPS54xx0-Q1 and TPS57xx0-Q1 devices have few differences in electrical parameters as listed inTable 2. These electrical parametric changes are achieved by implementing minor changes in metallayer
