What is Task Concept and what is Flat Interrupt Concept? What should I know about it?
The very first C166 compiler originated from Siemens. Its design reflected the task-oriented nature of the SAB 80C166 microcontroller. It introduced an extra scope level between local and global (or module and application) scope: the TASK scope. This concept allowed for a high grade of modularity and code-reusability. The TASKING C166 compiler was designed with this concept in mind. The Task Concept was implemented by running a separate linker and locator phase in the L166 linker/locator. The first phase links all object modules into a Task Object module (default extension is .LNO). In this phase all references within the task are resolved and libraries can be linked which are called solely by functions in this task. The second phase takes all Task Object modules together and locates the application into memory. In practice, most users did not use this feature and linked their entire application into a single task. Besides, we noticed that many customers found the unusual concept too r
