SN75DP130 Implementation Guide: DP130 in a Sink

This document describes how the multichannel buffered serial ports (McBSPs) in the Texas Instruments TMS320C6000™ digital signal processor (DSP) are used to communicate to a single-rate Serial Telecom (ST)-BUS-compliant device.

The McBSP receives the framing signal clock and data from the ST-BUS™ device and processes them to generate internal frame syncs and clocks for correct data

Analog switches are extensively used for switching audio signals in battery-powered applications such as mobile phones. In any cases the switch is powered directly from the battery but it receives control signals from a lower voltage processor GPIO. For most analog switches this application condition leads to an excess supply current draw that catches system designers by surprise. This applica

Digital signal processing algorithms are loop intensive by nature which presents a set of choices for the programmer working with the Texas Instruments (TI)(tm) TMS320C6x digital signal processor (DSP). Loops are implemented on the C6x with a branch instruction. To maintain the determinism of operations within the C6x pipeline a branch and its five delay slots are non-interruptible. The C6x code

Delta Sigma PLLs Raise The Standard For Performance

This application note describes how to extend the functionality of the standard hardware UART available on Stellaris® microcontrollers by using the 9-bit UART add-on.

The ADS8364 16-bit parallel output analog-to-digital converter has a number of features that allow for an easy interface to a variety of digital signal processors (DSP) from Texas Instruments. This application note focuses on configuring sampling and converting analog data presented to the ADS8364 ADC using software control with the TMS320C6711? DSP starter kit. In this application McBSPa is u

This document is a specification for the ELF-based Embedded Application Binary Interface (EABI) for the MSP430 family of processors from Texas Instruments. The EABI defines the low-level interface bet

This application report describes how the LMV112 clock buffer amplifier can resolve clock interferenceissue among different chipsets.

Advanced Topics in Powering FPGAs

Li-ion battery applications requiring five or more series cells can make use of standard 4-series-cell secondary protectors such as the bq2941x series. The devices can be stacked as necessary and outputs of individual devices can be combined with optocouplers to produce a single alarm signal if any cell exceeds the threshold. In addition for undervoltage protection TLV3011 nanopower comparato

This document discusses how to efficiently share memory with a DSP and a host without needing expensive dual-port RAMs. It includes a block diagram and a discussion of the bus arbitration issues.
