想要用ARM或DSP实现4K视频图像 H264或265的解码

Other Parts Discussed in Thread: AM5706, AM5708, AM5716, AM5718, AM5726, AM5728, TMS320C6678

需要实现4K视频图像的解码 H264或265,之前想要用AM57X系列来解码,因为硬件设计中本来就需要一块儿ARM,AM57x系列有解码硬件电路,我看了一下数据,支持H264,但是资料里显示支持1080p,如下:

 AM5706AM5708AM5716AM5718AM5726AM5728
ARM Cortex-A15 (MHz) Single core @ 500MHz/1.0 GHz Single core @ 1.0 GHz Single core @ 500MHz/1.5 GHz Single core @ 1.5 GHz Dual core @ 1.5 GHz
C66x DSP (MHz) Single core @ 500/750 MHz Dual core @ 750 MHz
ARM Cortex-M4 (MHz) Dual core @ 213 MHz
PRU-ICSS* Quad core @ 200 MHz
Graphics   Single core SGX544 (3D GPU)
Single core GC320 (2D GPU)
  Single core SGX544 (3D GPU)
Single core GC320 (2D GPU)
  Dual core SGX544 (3D GPU)
Single core GC320 (2D GPU)
Video Acceleration   1080p encode and decode   1080p encode and decode   1080p encode and decode
Display   Yes   Yes   Yes
 Pin and software compatible

请问AM57x可以实现我需要处理的最高4K的要求么?或者性能方面会不会有所降低?或者各位有没有好的替代建议,谢谢啦
