ADSP-BF548 高性能汇聚式多媒体Blackfin处理器

ADSP-BF548专门针对汇聚式多媒体应用而设计；在这些应用中，系统性能和成本是关键考虑因素。该处理器集多媒体、人机界面、连接外设与更高的系统带宽和片内存储器于一体，为客户设计要求严苛的应用提供了一个平台。

在当今的嵌入式应用中，知识保护已成为不可或缺的一部分。ADSP-BF54x采用包含OTP存储器、基于固件的安全解决方案，用户通过私人密钥，才能安全地访问程序代码，从而在灵活性、可升级性与性能之间实现平衡。

ADSP-BF548的外设灵活性与高性能处理相辅相成。这些丰富的系统级外设非常适合先进车载信息娱乐系统和工业多媒体应用；此类应用普遍支持多种标准，并且对系统性能有很高要求。

为增强连接能力，该处理器还集成内含PHY的高速USB On-the-Go (HS USB OTG)模块，以及8/16位主控DMA接口。通过这些系统级外设，以及多种片内SPORT、SPI、UART、TWI和CAN接口所提供的标准串行连接，可以与消费类电子和通信产品、蓝牙以及其它专用接口等多种片外设备实现无缝连接。对于车载信息娱乐系统和多媒体市场不断变化的新兴产品和标准，这种集成度最为理想。

ADSP-BF548配有SD/SDIO控制器、ATAPI-6控制器和8/16位NAND闪存控制器，可以与硬盘、CD/DVD驱动器和NAND闪存产品等存储介质实现片外连接。

ADSP-BF548还提供许多多媒体增强功能，通过硬件集成减轻处理器MIPS负担，扩展显示能力，并缩短客户开发周期。现在，支持ITU-R BT.656视频格式的多种增强并行外设接口也可以驱动18/24位液晶显示器。该处理器通过一种新开发的硬件加速模块（“像素合成器”）来执行叠加、色彩转换和α混合。此模块可以显著降低与软件RGB-YUV色彩转换和α混合相关的处理器内核开销。

在人机界面方面，ADSP-BF548提供一个32位升降计数器，它可以检测通常由工业驱动器或手动拇指滚轮发射的2位正交或二进制码。此外还包括一个8 x 8键盘接口。
