Although it is a generic case study design - not an actual implementation - a real time video/ audio/ motion (VAM) recording system highlights a number of key operating system features and services that must be considered in any embedded system design, including:
- application timers
- threads
- message queues
- mutexes
- memory byte pools
Our design provides the ability to record several events within each 24-second time frame, rather than just one. Application timers play a major role in providing this feature. We also used application timers to simulate interrupts that signify the occurrence of events, and we used one timer to display periodic system statistics.
