描述

TMS320C6745 /6747器件是一款基于TMS320C674x DSP内核的低功耗数字信号处理器。它的功耗显着低于TMS320C6000 DSP平台的其他成员。

TMS320C6745 /6747器件使原始设备制造商（OEM）和原始设计制造商（ODM）能够快速推出市场上的设备。高处理性能。

TMS320C6745 /6747 DSP内核采用基于缓存的两级架构。 1级程序高速缓存（L1P）是32 KB直接映射高速缓存，1级数据高速缓存（L1D）是32 KB双向组关联高速缓存。 2级程序高速缓存（L2P）由256 KB内存空间组成，在程序和数据空间之间共享。 L2内存可以配置为映射内存，缓存或两者的组合。虽然系统中的其他主机可以访问DSP L2，但是其他主机可以使用额外的128KB RAM共享内存（仅限TMS320C6747），而不会影响DSP性能。

外设集包括：带管理数据输入/输出（MDIO）模块的10/100 Mbps以太网MAC（EMAC）;两个I ² C总线接口; 3个多通道音频串行端口（McASP），带有16/9串行器和FIFO缓冲器;两个64位通用定时器，每个都可配置（一个可配置为看门狗）;可配置的16位主机端口接口（HPI）[仅限TMS320C6747];多达8个16引脚的通用输入/输出（GPIO），具有可编程中断/事件生成模式，与其他外设复用; 3个UART接口（一个具有 RTS 和 CTS ）;三个增强型高分辨率脉冲宽度调制器（eHRPWM）外设;三个32位增强型捕获（eCAP）模块外设，可配置为3个捕获输入或3个辅助脉冲宽度调制器（APWM）输出;两个32位增强型正交编码脉冲（eQEP）外设;和2个外部存储器接口：用于较慢存储器或外设的异步和SDRAM外部存储器接口（EMIFA），以及用于SDRAM的高速存储器接口（EMIFB）。

以太网媒体访问控制器（EMAC）提供TMS320C6745 /6747器件与网络之间的高效接口。 EMAC支持10Base-T和100Base-TX，或半双工或全双工模式下的10 Mbps和100 Mbps。此外，MDIO接口可用于PHY配置。

丰富的外设集可以控制外部外围设备并与外部处理器通信。有关每个外围设备的详细信息，请参阅本文档后面的相关章节以及相关的外围设备参考指南。
