多核数字信号处理器(DSP)具有丰富的外设接口,每个外设接口具有各自独立的参考时钟。由于多核 DSP 具有较快的数据处理能力,对外设接口的时钟要求较高。当多个接口协同工作时,对时钟的同步要求较高。本文介绍了多核数字信号处理器TMS320C6678的时钟设计,通过时钟芯片CDCM6208提供多路不同工作频率的时钟信号到DSP,文中介绍了时钟芯片的初始化和设置以及详细的软硬件设计方法。

These are many interfaces on multicore DSP,and each clock should be set independently.Higher frequency and steadiness is required for these clocks to fit the multicore DSP.These clocks are originated from one high precision reference clock.TMS320C6678 clock design is introduced,getting diversified clock based on CDCM6208.The paper introduces how to set CDCM6208,and the design of hardware and software is described.
