How system calls implemented in RTOS

Apart from the scheduler, how system calls are implemented in Real-Time Operating Systems?

JAVA in Embedded

Conventional Embedded systems involved only C and assembly languages. Now a days, the requirements for embedded systems widened beyond C and Embedded Database, Java and C++ in embedded systems become hot topics. So, let's update about the latest trends.

RTOS metrics

・Memory footprint → memory usage, RAM & ROM requirements
・Latency
    ・Interrupt latency
    ・Scheduling latency
・Services performance→Minimum time taken by a system call

Interesting Story: Android

http://en.wikipedia.org/wiki/Android_(operating_system)

From RTC magazine,

"Certainly, Android is not ideal for all types of device designs. It presents a dazzling array of features and capabilities for mobile/wireless devices and an attractive OS option for other intelligent devices. In particular, Android is a viable alternative for designs that benefit from a graphical user interface, field-upgrade capability, a complement of ready-to-use applications, and both Java-style and native C/C++ runtimes.

It is a less attractive choice for

• Headless devices
• Devices with extremely limited RAM and persistent storage
• Closed-box designs
• Legacy support for RTOS APIs and other specialized interfaces
• Systems with pervasive hard real-time / low-latency response needs
• Designs built on “minority” CPU families or special-purpose silicon"
