Troubleshooting | High Compute Resource Usage by Delay Matrix Mixer in Q-SYS Core

Managing Processing Overruns by Adjusting Delay Matrix Mixer Component and Design Size

Updated at September 24th, 2024

Affected Products

Hardware Model/Series
Q-SYS Core
Software
QDS v8.0 and 9.4.4 LTS

Problem | Symptoms

The Delay Matrix Mixer component’s compute resource usage may be higher than anticipated by the design compiler. This can lead to processing overruns in the design.


Causes | Verification

The issue is caused by the Delay Matrix Mixer component consuming more compute resources than expected. This can be verified if the design experiences processing overruns.


Solution | Workaround

To mitigate this issue, you can reduce the design size by:

  • Reducing the size of the Delay Matrix Mixer component(s)
  • Reducing the Max Delay property
  • Removing other components from the design
  • Any combination of the above methods
