OMAPL138的两个核心是否可以不同频率运行?

Other Parts Discussed in Thread: OMAP-L138

您好,我在开发手持的138程序时碰到问题。我需要DSP处于较高频率,但是ARM负载很轻。

目前设想希望DSP运行于360M   ARM运行于120M。但经过测试设置arm频率时DSP也会跟着降低。(使用/sys下的设置接口,ARM使用linux3.3),请教ARM和DSP是否能够使用不同频率?对于L138的节能和休眠除了《SPRUH77C OMAP-L138 C6000 DSP+ARM Processor Technical Reference Manual (Rev. C)》之外还可以参考哪些文档?
