About the Data Streams Optimizer
The data streams optimizer focuses on tuning the I/O fabric to enhance the transfer of data between two processor subsystems. In the context of the tool, the transfer of data is referred to as
data streams
. The tool also changes system power management. It reduces power management to satisfy the most stringent real-time requirements, or increases power management in cases where the real-time requirements are more relaxed. This makes the data streams optimizer a powerful tool that ensures the system is optimally configured for a given use case.In this release, processor subsystems include memory, processor cores, and PCIe endpoint.
Steps:
- Specify your requirements, such as latency and bytes per transfer, for data movement between these entities.
- The tool identifies the control points between these entities that could be tuned to meet the requirements.
- The tool performs tuning by writing specific values to registers for the control points.
- The tool instructs the boot firmware to write the values to those registers upon the next boot and then triggers a reboot of the system.
