Testing Real-Time Performance on a Networked Media Device (Windows Embedded CE 6.0)

1/5/2010

The following table shows two utilities that you can use to analyze real-time requirements in your networked media device. Each of these utilities has sample applications in the %_WINCEROOT%\PUBLIC\COMMON\OAK\UTILS directory.

Utility	Description
ILTiming.exe	Measures interrupt service routine (ISR) and interrupt service thread (IST) latencies.
OSBench.exe	Analyzes the performance of the thread scheduler by measuring the execution time of basic kernel operations.

Analyzing the performance of real-time applications involves looking at a set of hardware, operating system, and application elements.

The following table shows topics that provide background information about the elements of real-time performance.

Topic	Description
Real-Time Performance Functionality	Provides background information about the elements of real-time performance.
Real-Time Measurement Tools	Provides information about tools to help you measure real-time performance in the kernel.
Demand Paging Considerations	Provides background information about how paging impacts performance.
File System Considerations	Provides background information about how the use of critical sections impacts performance.
Graphics, Windowing, and Events Subsystem Considerations	Provides background information about how Graphics, Windowing, and Events Subsystem (GWES) choices impact performance.
System Timer Considerations	Provides background information about how the Sleep API impacts performance.
Power Management Performance Considerations	Provides background information about how power management cycling impacts performance.
Peripheral Access Considerations	Provides background information about how the system bus and the real-time impact performance.
