Hi,

EPPI can work at clock of upto 83.3 MHz under certain conditions as mentioned in the datasheet.

EPPI supports a mode where two DMAs can be used to read the data from EPPI stream. These two DMA can extract data form even and odd locations and deposit them in different buffers in memory.

DMACFG decides whether PPI uses one or two DMAs.

SPLTEO can also be used to pack the data from even and odd locations separately.

Regards,

Nabeel

If output format of video decoder is mux mode, can trigger signal is triggered by synchronization signal of Eppi ?

Trigger of Eppi is triggered by synchronous signal of data of video. When trigger of Eppi is triggered, DMA is started.

But synchronous signal of every channel is differ position, so how to detect synchronous signal of every channel ?

How to trigger of Eppi be triggered in mux mode?
