Question

How to find number of machine cycles for instruction in 8085?

Answer 1

Many older - almost 'classical' - microprocessors such as the 8080, 8086 and Z80 have complete lists of instructions and T states published and freely available.

You can find these in books such as “Digital computer electronics” or if you search awhile on the internet - just use Google.

Although I highly doubt that you will be able to find this information for modern day CPUs from Arm, AMD and Intel.

In terms of machine cycles I can answer this for you right now, without you having to look it up.

Each instruction, no matter length and size, will always use one machine cycle, because this is the definition of a machine cycle. The complete execution of one instruction is called a machine cycle!*
