Embedded Systems Design Embedded

The document summarizes the results of a survey of thousands of embedded systems developers on their use of operating systems. Some key findings: - Over 28% of projects do not use an OS, most citing lack of need. Commercial OS usage is rising while in-house OS usage is declining. - VxWorks is the most commonly used commercial OS at over 25%. Windows Embedded products and DSP/BIOS also ranked highly. - Open-source OS enthusiasm is waning, with fewer developers planning to use Linux compared to last year's survey. - Real-time performance, processor compatibility, and available tools are most important in OS selection. Non-technical factors are also increasingly important.
