HDVPSS conversion performance on DM8168

Pearse Ffrench

How many frames per second can the HDVPSS convert from 1080i to 480i via a memory to memory conversion? Looks like the HDVPSS has multiple conversion units and so the number I am looking for is the total across all conversion units since I have multiple indepedent video streams that I am converting.

Hi,

Can you please let us know your usecase. It will be easy to estimate your usecase. Number of conversion depends on many things like number of displays required, input and output data formats etc.

There is no display required. The data flow is

1) H.264 1080i (from IP interface) to 1080i baseband video (420) by using the HDVICP2

2) 1080i (420) to 480i (422) using the HDVPSS (memory to memory)

3) 480i (422) baseband video data transmitted out the PCIe interface

This is done for multple streams simultaneously. So, how many conversions can be done by #2 per second?

Hi,

If you dont want to use displays you have 5 scalars possible. Each scalar can comfortably do 1080i120FPS so total 5 scalars can do 120*5=600FPS that is 600 frames per second.
