problem 1: Describe the role of interrupt handling. Why are interrupts mainly used?
problem 2: Discuss system architectures issues in evolution of x86 Intel processor family (segmentation, virtual memory, paging unit, floating point hardware, instruction pipeline and so on).
problem 3: Discuss different assembly language issues including relationship between assembly language statements, binary codes, and segment: address offsets. Describe the effects on various registers of executing assembly language statements.
problem 4: Give four various kinds of interrupts? describe what is special in each kind?
problem 5: How is an interrupt visible to the program in execution?
problem 6: How is an interrupt visible to the processor?
problem 7: How are interrupts processed?
problem 8: How does the system know whether some memory location contains an integer number, floating point number or a machine instruction? What occurs, if during an integer add instruction one encounters a floating point value in one of the argument registers?
problem 9: Which problem does the cache memory resolve? How is the solution implemented?
How can application programmer best persuade the proper operation of this solution?
problem 10: Which problem does the virtual memory resolve? How is the solution implemented? How can application programmer best persuade the proper operation of this solution?
