DM3725CUS100 Texas Instruments DSP

DM3725CUS100 Overview

The DM37x generation of high-performance, applications processors are based on the enhanced device architecture and are integrated on TI's advanced 45-nm process technology. This architecture is designed to provide best in class ARM and Graphics performance while delivering low power consumption. This balance of performance and power allow the device to support the following example applications:

Portable Data Terminals
Navigation
Auto Infotainment
Gaming
Medical Imaging
Home Automation
Human Interface
Industrial Control
Test and Measurement
Single board Computers

The device can support numerous HLOS and RTOS solutions including Linux and Windows Embedded CE which are available directly from TI. Additionally, the device is fully backward compatible with previous Cortex?-A8 processors and OMAP? processors.
