The first optimization step that can be performed on C source code for the TMS320C6000™ DSP platform is to use intrinsic operators. These are built-in functions in the compiler that can be directly translated to assembly code for faster execution. The C6000 DSP family fixed-point processors are organized into two main families: the TMS320C62x™ DSP and the TMS320C64x™ DSP. The C6
This application note describes how to modify the TI-MAC (v1.3.0) / Z-Stack (v2.2.0) software releases for the CC2530 SoC to support CC2591 PA/LNA controls.
This application report describes and shows how to implement a single-chip thermocouple interface without using the signal conditioning circuitry normally required for thermocouples. The thermocouple
Flexible AC Transmission Systems (FACTS) are thyristor based means for highly dynamic load flow control in electrical power supply and distribution. These newappliances have an impact on network parameters like transmission angle nodevoltage line current and harmonics. Thus the control of FACTS equipmentprovides a highly dynamic view of these parameters. For this purpose wedeveloped th
This application report discusses the power consumption of the Texas Instruments TMS320DM6467T digital media System-on-Chip (DMSoC). Power consumption on the DM6467T device is highly application-dependent; therefore a spreadsheet that estimates power consumption is provided along with this document. To obtain good results from the spreadsheet realistic usage parameters must be entered (see Secti
SYS/BIOS is designed for use in embedded applications that need real-time scheduling synchronization and instrumentation. It provides preemptive multitasking hardware abstraction and memory management.This application report uses an adaptation of the capacitive touch library to interface with SYS/BIOS. Thisinterface abstracts the capacitive touch interface promoting use of the graphical c
Most battery monitor ICs from TI including the bq2018 and bq2019 includes a single-wire HDQ serial data interface. Host controllers configured for either polled or interrupt processing use the interface to access various IC registers. The purpose of this application note is to cover most of the communication related topics for these devices.
Modern trends are driving the need for lower supply voltages across many system-level designs. As most processor voltage levels continue to decrease in the interest of achieving the lowest possible power consumption peripheral devices maintain a need for higher voltage levels creating potential for voltage discontinuities within a system. To remedy this mixed voltage system incompatibility a vo
This report describes the software and circuits necessary to interface to numerous members of the TMS320 family. Specifically it presents three circuits for interfacing the TLC32040 Analog Interface Circuit to the TMS320 digital signal processors:- TMS32010/E15 Interface to the TLC32040- TMS32020 Interface to the TLC32040- TMS320C17 Interface to the TLC32040 Each circuit section i
The synchronization of multiple PWM and PFC controllers is desirable for many reasons. The most common reason is that it keeps all the noise at one particular frequency and makes it easier to filter. The circuit described changes the slope of the ramp to lock the converter’s switching frequency to an applied signal by a phase locked loop turning it into a voltage controlled oscillator. Furthermore
This application report presents high-current LED driving requirements that use the TI integrated boost converter IC TPS6106x and integrated buck converter IC bqSWITCHER™ (bq2410x/11x/12x). Step
This report describes how to construct a gain block diagram for a current feedback op amp and relates the diagram to stability and gain analysis using parameters of the THS3001 op amp.
This document describes two solutions used to provide a reset circuit to the Texas Instruments (TI)(tm) TMS320C6000 digital signal processor (DSP). One solution sets a supply voltage supervisor such as the TI TLC7733 and TLC7725 on each of the supply voltages DVdd and CVdd. Another solution monitors both the 2.5-V/1.8-V and 3.3-V power supplies using a single supervisor such as the TI TPS3707.
