OMAP5912数据手册集成电路（IC）的微处理器规格书PDF

描述 Description

OMAP5912 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 reduced instruction set computer (RISC)technologies, incorporating a TMS320C55x DSP core and a high-performance ARM926EJ-S ARM® core.
