OMAP5910中文资料应用处理器数据手册TI规格书

描述 Description

The OMAP5910 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 TI925T 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.

The OMAP5910 is targeted at the following applications:

Applications processing devices Mobile communications 802.11 Bluetooth™ wireless technology GSM (including GPRS and EDGE) CDMA Proprietary government and other Video and image processing (MPEG4, JPEG, Windows® Media Video, etc.) Advanced speech applications (text-to-speech, speech recognition) Audio processing (MPEG-1 Audio Layer3 [MP3], AMR, WMA, AAC, and other GSM speech codecs) Graphics and video acceleration Generalized web access Data processing (fax, encryption/decryption, authentication, signature verification and watermarking)
