SYSTEM PERFORMANCE ANALYZER
The system performance analyzer visually displays records of executed tasks and RTOS resource ac-
cess data, thereby clarifying the task load status and making it easy to determine the tuning index.
Quantitative Evaluation Index
In a system constructed using a design
the CPU's performance and resources, and is used to assess the system performance and analyze its opera-
tion, through which system performance and product quality can be raised.
Tuning work usually involves checking the following operations and then analyzing the system's response per-
formance.
Response Performance Analysis
Algorithms and the system configuration concept can be changed at the design stage, based on analysis
results. The tool that supports this kind of analysis and modification is the system performance analyzer (AZ).
This performance analyzer, operated in combination with one of a variety of debuggers, has the following functions.
The system performance analyzer displays trace data visually and provides the following functions for software
operation control, thus facilitating task operation analysis.
Verification/analysis of real-time system execution performance
Adequacy of access division (task run time)
Selection of optimal scheduling (task priority level)
Optimal resource allocation (resource utilization efficiency, resource values)
Detection of bugs caused by system timing misses
Detection of problems caused by the simultaneous operation of multiple tasks
Detection of unnecessary system processing
Support of source analysis
Clarification of the system tuning index
