Hi,

We are checking the feasibility of using FX3S in one of our project.We have some queries regarding this.

1. What is the data storage bandwidth to store a file in FAT Fs in EMMC?

2. If we interface H264 Encoded stream through GPIF ,how can we  wrap H264 to mp4 container?

Thanks in advance.

Hello,

1. What is the data storage bandwidth to store a file in FAT Fs in EMMC?

>> Please refer to USB to Storage block throughput  USB to SD throughput with EZ-USB™ FX3S, EZ-USB™ SD... - Infineon Developer Community   . Please note this not the data for storing FATFs

2. If we interface H264 Encoded stream through GPIF ,how can we  wrap H264 to mp4 container?

>> Please let me know what processing needs to be done to wrap H264 to mp4. If it requires the frame data to be stored and then processed, we would recommend to do the processing/conversion on FPGA due to the RAM constraints of FX3S (512KB). MP4 frames can be sent by FPGA to FX3S. If the conversion doesn't require too much processing then it can be done on FX3S

Regards,
Rashi

Hi Rashi,

                 Thanks for the reply. We are looking for a reference/evaluation board which contains CYUSB3035-BZXC,which has GPIF interface as well as SDIO.But we couldn't find any.Can you please help us to get an evaluation board with CYUSB3035-BZXC chip.
