Q. Explain Execution-modes of a multiprocessor?
Execution-modes of a multiprocessor: Several modes of multiprocessing comprise parallel execution of programs at (i) Fine Grain Level (Process Level), (ii) Medium Grain Level (Task Level), (iii) Coarse Grain Level (Program Level).
For executing programs in these modes below conditions/actions are needed at OS level.
i) Context switching between multiple processes must be fast. In order to have context switching easy multiple sets must be present.
ii) The memory allocation to several processes must be context free and fast.
iii) Synchronization mechanism among multiple processes must be effective.
iv) OS must offer software tools for performance monitoring.
Microprocessor have ROM chip because it have instructions to implement data. It have the monitor program which not only include implementation instruction but also interfacing

Subtraction of 01000-01001 using 2's complement method. Ans. Firstly 1's complement of 01001 is 10110 and 2's complement is 10110+ 1 =10111. Thus 01000 = 01000 - 01001
