Dec 28, 2019 · The stack is used by the task itself (e.g. when calling functions). The TCB is used by the OS to manage the task. Refer to your processor user manual to find out how interrupts are acknowledged. It may be that the hardware saves some context on the stack of the interrupted thread, e.g. flags, instruction pointer. A quasi-reentrant program is a program that is in a consistent state when control is passed to it, both on entry, and before and after each EXEC CICS command. Such quasi-reentrancy guarantees that each invocation of an application program is unaffected by previous runs, or by concurrent multithreading through …

A task can exist in one of the following states: Running. When a task is actually executing it is said to be in the Running state. It is currently utilising the processor. If the processor on which the RTOS is running only has a single core then there can only be one task in the Running state at any given time. Ready. This record or data structure is called Process Control Block (PCB). Whenever a user creates a process, the operating system creates the corresponding PCB for that process. These PCBs of the processes are stored in the memory that is reserved for the operating system. The process control block has many fields that store the …
