can we port an RTOS and embedded c code in the same chip? what exactly is the tasks referred in RTOS(VxWorks). IS a task in VxWorks an embedded c code? Is the RTOS just used for maintaining the time constraints of processor? Where exactly is the RTOS loaded in real time project (in target board or host system or control room system etc ) and how is it useful? Kindly do reply to these queries if u know it. I am facing problems as i am into an embedded project dealing with QNX rtos for my company.
