1. ► ALU is part of datapath.

2. ► ISA has the details of cycle level information of the processor.

3. ► Behaviour of programmable systems cannot be changed.

4. ► Presence of ROM and RAM provides possibility of parallel access.

5. ► An instruction can be executed without decoding.

6. ► An instruction refers to a basic operation.

7. ► An instruction need not be unique.

8. ► Decoding refers to figuring out what to do with the instruction.

9. ► Micro-architecture has the complete details of the processor.

10. ► A jump leads to direct modification of program counter.

11. ► During instruction fetch, instruction is usually put on the address bus.

12. ► Decoder reads instruction from IR.

13. ► Hardware programmability is not at all possible.

14. ► Instead of having both ROM and RAM, it would suffice to have just one memory.

15. ► ROM can be modified at run-time.

16. ► Printer is a non-programmable system.

17. ► Binary encoding of instruction need not be unique.

18. ► A microcontroller can work without register file.

19. ► As long as ISA is same for two processors, program from one of the them to other is portable.

20. ► CPU can understand assembly code.
