Lesson 1: Monitoring and Optimizing System Performance

Performance monitoring and optimization are important tasks in the development of small-footprint devices. The need for optimized system performance remains critical because of an ever-growing number of increasingly complex applications and the requirement for intuitive and therefore resource-intensive user interfaces. Performance optimization requires firmware architects and software developers to constrain resource consumption within their system components and applications so that other components and applications can use the available resources. Whether developing device drivers or user applications, optimized processing algorithms can help to save processor cycles, and efficient data structures can preserve memory. Tools exist at all system levels to identify performance issues within and between drivers, applications, and other components.

After this lesson, you will be able to:

? Identify the latency of an interrupt service routine (ISR).

? Improve the performance of a Windows Embedded CE system.

? Log and analyze system performance information.

Estimated lesson time: 20 minutes.
