Question

For a 25 MHz processor, what is the time taken by the instruction which needs 3 clock cycles _______________.

• A. 120 nano secs
• B. 120 micro secs
• C. 75 nano secs
• D. 75 micro secs

Answer 1

The correct option is D 75 micro secs

For a 25 MHz processor, the time taken by the instruction which needs 3 clock cycles is 75 micro secs.

A one-megahertz clock (1 MHz) means some number of bits can be manipulated at least one million times per second. The speed of microprocessors, called the clock speed, is measured in megahertz.

Processor(computing), central processing unit (CPU), the hardware within a computer that executes a program. Microprocessor, a central processing unit contained on a single integrated circuit (IC) application-specific instruction set processor (ASIP), a component used in system-on-a-chip design.
