I found few answers for my question while i tried these concept in programming. Please see and comment
So many ways to print the size of the processor. Logic 1: ====== 1. Remember the stack point address. 2. Push accumulator content in to stack. (In Assemble PUSH A will do this) 3. Get the new stack pointer location. Check how many bytes stack pointer has moved because of this push inst. That is the processor size. Logic 2: ====== 1. Store 1 in Acc. 2. Keep shift left the ACC content till CARRY flag is set. For every shift, get it counted. 3. Once carry flag is set, get the counter value. That is processor size. Logic 3: ====== Minimum size of the processor would be 8 bit. Right. 1. Move FF into Accumulator. 2. Add 1. If carry flag is not set, then the processor is not 8 bit. If it is set, processor is of 8 bit. 3. Else Move FFFF and repeat the steps from 2. |

| thanks but could u clarify | 01/01/70 00:00 | |
| I think you missed the point | 01/01/70 00:00 | |
| Various compilers different results | 01/01/70 00:00 | |
| Word size - not code size? | 01/01/70 00:00 | |
| u r correct | 01/01/70 00:00 | |

| Correct ! | 01/01/70 00:00 | |
| not sure what you would do with the information | 01/01/70 00:00 | |

| Great! Now do it in C | 01/01/70 00:00 | |
| Same logic for C and asm | 01/01/70 00:00 | |
| No, it isn't. | 01/01/70 00:00 | |
| What would be the point? | 01/01/70 00:00 | |
| It is worse than that | 01/01/70 00:00 | |
| the whole question is silly | 01/01/70 00:00 | |
| It can even get this silly... | 01/01/70 00:00 | |
