Why do we need the "nop" I.e. No operation instruction in microprocessor 8085?
One use of NOP (or NOOP, no-operation) instruction in CPUs and MCUs is to insert a little, predictable, delay in your code. Although NOPs don't perform any operation, it takes some time to process the …

Why do Microcontrollers need a Clock
MCUs are only one very complex example of a synchronous sequential logic circuit. The simplest form is probably the clocked D-flip-flop (D-FF), i.e. a synchronous 1 bit memory element.
There are memo …

What happens if clock cycle is replaced with constant high voltage in a processor?
Your doubts arise from lack of understanding of the basics about synchronous sequential logic networks, of which modern CPUs and related basic blocks, like counters, are just particular examples.
As s …
