OMAP5910

应用处理器

The is a highly integrated hardware and software platform, designed to meet the application processing needs of next-generation embedded devices.

The OMAP™ platform enables OEMs and ODMs to quickly bring to market devices featuring rich user interfaces, high processing performance, and long battery life through the maximum flexibility of a fully integrated mixed processor solution.

The dual-core architecture provides benefits of both DSP and RISC technologies, incorporating a TMS320C55x DSP core and a high-performance 925T ARM core.

The OMAP5910 device is designed to run leading open and embedded RISC-based operating systems, as well as the Texas Instruments TI DSP/BIOS™ software kernel foundation, and is available in a 289-ball MicroStar BGA package.
