Here are questions about FX3 and need Cypress' advice.

-------------------------------------

1. Could  FX3 support line buffer for Streaming Frame? Ex: receive 10 line input via ISP , then output 10 line data directly. Or FX3 need wait a full Frame for output ?

2. If FX3 is frame base buffer (need wait full frame) , what is the output latency ? 1/fps second ?

3. If FX3 could support line buffer , what is the minimum output latency (or how many line)?

4. For FX3 ISO mode, the Throughput(bandwidth) is 82700KBps , around 3GBps. Does it mean the max bandwidth is “streaming  resolution x fps x bit/pixel”? ex: 4656x3496(16M) x 4~5fps x 16bit/pixel (please refer to the attachment, there is a table inside it)

5. Could FX3 support add frame count information for each frame ?

-------------------------------------

Regards,

Kyle

Hello,

1. No.

2. Same to Q1.

3. You could calculate the latency time consumed by FX3/CX3 to fill buffer. Check the link below.

Calculate FX3/CX3 latency in Video Streaming Design - KBA223271

4. Please tell me the context of the table 2.

5. Yes, it's feasible to do that. FX3 adds UVC header for each DMA buffer. Please refer to AN75779.
