0. In the architecture of 8085 microprocessor match the following:
| (a) Processing Unit | (i) Interrupt |
| (b) Instruction unit | (ii) General Purpose Register |
| (c) Storage and Interface unit | (iii) ALU |
| (iv) Timing and Control |
| (a) | (b) | (c) | |
| (1) | (iv) | (i) | (ii) |
| (2) | (iii) | (iv) | (ii) |
| (3) | (ii) | (iii) | (i) |
| (4) | (i) | (ii) | (iv) |
- Option : B
- Explanation :
- ALU is the arithmetic logic unit and it involves processing of input into desired output.
- Timing and control instruction are covered in instruction unit of microprocessor.
- There are some general purpose register in storage and interface unit.
- While an interrupt is a signal to the processor which required attention from processor, an interrupt is serviced on the basis of priorty and need.
So, option (B) is correct.
