器件型号：TDA4VM 工具/软件：
我的 SDK 版本：RTOS 10.01.00.04
尊敬的 TI 专家：
我将根据"app_tidl_avp4"创建一个自定义应用、并进行了以下两项更改：
- 将显示输出更改为 SRV
- 将 TIDL 从 SEG 更改为 OD
这种变化导致了整个图的性能下降、现在大约为20fps。

我认为、通过将图形分为两个、一个用于 SRV 侧、一个用于 OD 侧、我可以提高性能。(下图中的红色和蓝色区域)
但将图形拆分为两并没有提高性能。

我的目标是让 SRV 以30fps 运行、OD 以15fps 运行。 您能给我一些建议、我该如何实现这个目标吗？
此致、
