- Cyclic_executive abstract "A cyclic executive is an alternative to a real-time operating system. It is a form of cooperative multitasking, in which there is only one task. The sole task is typically realized as an infinite loop in main(), e.g. in C.The basic scheme is to cycle through a repeating sequence of activities, at a set frequency. For example, let us consider the example of an embedded system designed to monitor a temperature sensor and update an LCD display. The LCD may need to be written ten times a second (i.e., every 100 ms). If the temperature sensor must be read every 50 ms for other reasons, we might construct a loop of the following appearance:int main(void){ // initialization code here while (1) { currTemp = tempRead(); lcdWrite(currTemp); // waste CPU cycles until 50 ms currTemp = tempRead(); // do other stuff // waste CPU cycles until 100 ms }}The outer 100 ms cycle is called the major cycle. In this case, there is also an inner minor cycle of 50 ms.".
