Texas Instruments OMAP5910 Dual-Core Applications Processor

Texas Instruments OMAP5910 Dual-Core Applications Processor 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 benefits DSP and RISC technologies, incorporating a TMS320C55x DSP core and a high-performance TI925T ARM core. The Texas Instruments OMAP5910 is designed to run leading open and embedded RISC-based operating systems and the Texas Instruments (TI) DSP/BIOS™ software kernel foundation. The device is available in a 289-ball MicroStar BGA package.
