Differences between Multiple Tasks and Multiple Processes

Question

What are differences between Multiple Tasks and Multiple Processes?

Answer 1

• Several embedded computing systems do more than one thing which is, the environment can cause mode changes which in turn since the embedded system to behave stop differently.

• A text compression box gives a simple illustration of rate control difficulties. A control panel on a machine gives an illustration of a different kind of rate control problem, the asynchronous input.

• Multirate embedded computing systems are extremely common, including printers, telephone PBXs and automobile engines.

• The co-routine was a programming method commonly utilized in the early days of embedded calculating to handle multiple processes.

• The ARM code within the co-routines is not intended to show meaningful computations.

• The co-routine structure permit us implement more general types of flow of control than is possible along with only subroutines; the recognition of co-routine entry points gives us with several hooks for non-hierarchical calls and returns in the program.

• Although, the co-routine does not do nearly adequate to help us construct complicated programs with important timing properties.

• The co-routine in common does very small to simplify the design of code which satisfies timing needs.
