Syslink vs IPC 3.0 Performance

Hi,


I made some tests for hardware decoding on omap5 using syslink and IPC 3.0.

For decoding I used dce_test, the test file from libdce.

As input i used a 100 frames video with the resolution 1280x480.

When i used the syslink version i got the following time for decoding: 0,559 s (I measured only the codec processing time).

When i used the IPC version i got 1,336 s for decoding the same video (Also I measured only the codec processing time).

Why is that the time difference is so high? Isn't IPC 3.0 supposed to be at least as fast as Syslink, if not faster? Am I missing something?

Thank you,
