System Performance Modeling (SPM) offers system-level performance analysis for characterizing and evaluating the performance of hardware and software systems. In particular, it enables analysis of the critical partitioning trade-offs between the Arm® Cortex A9 processors and the programmable fabric for a variety of different traffic scenarios. It provides graphical visualizations of AXI transaction traces and system-level performance metrics such as throughput, latency, utilization, and congestion.
SPM can be used in two ways:
- Using a predefined design provided with the Vitis software platform
- With the user design
In the current release, SPM is supported only for baremetal/standalone applications.
The following diagram shows the system performance modeling flow.
