请问如要要给ip封装axi总线接口，编码好的比特流该写回memory吗？还是怎样处理；
另外还有一个问题想请教一下大家，编码p帧时参考帧的来源难道不是上一帧store_db_luma和store_db_chroma吗？为什么我发现load参考帧的数据并不一样，看了环境后我发现参考帧是memory由rec.yuv写进去的，这个是为什么呢？

@bo 你好，我还有一个点没懂，按理说我们编码第二帧的时候是以第一帧作为参考帧的，但是我发现第二帧的load_ref_Luma和load_ref_chroma并不是load的第一帧的重构帧，而是load TV目录下单独的ref.yuv，为什么呢？

@karthik_tdk I am a beginner in video encoding technology, and I have just come across this open-source project. I haven't studied it in depth, so I can't give guidance to others; besides, I know a little English.

@karthik_tdk In the v2.0 code, it seems that the current frame can be determined as an I-frame or a P-frame by configuring the IP input signal, sys_type_i. When it's 0, the current frame is an I-frame, and when it's 1, the current frame is a P-frame. There is a PPT that briefly introduces IP. You can check it out on this website.
