I am building Gstreamer tests for stereo & multichannel audio applications
using Linux on Arm 11 and Cortex 8 devices we are building.
What I am trying to determine is how to measure latency through the entire
I would like to perform DSP type of operations on ARM 11 and Cortex A8
devices and need to have some kind of quideline on realtime latency
The NEON SIMD engine latency under a Gstreamer application would be
interesting as well.
If anyone has some pointers or code examples it would be appreciated.
