A Hz is a measure of cycles per second. 25 MHz is 25,000,000 Hz. So divide 1 second by 25,000,000 to find the length of a clock cycle. 1/25000000 = 4.0e-8 seconds / cycle

What is the time to execute a 3 clock cycle instruction in a 25Mhz processor?
The time to execute a 3 clock cycle instruction in a 25MHz processor is 120ns. One clock cycle is 40ns, 1/25Mhz, so three of them are 120ns.
What do you mean by clock speed of a processor?
The number of clock cycles per minute which determines the spped of le system
Difference between system tick and processor clock?
Based on the Crystal used in the circuit, and the divisor selection, the processor clock frequency is obtained the tick time is the min clock cycles required to do a nop operation
How many clock cycles does the CPU require to act on a command?
It depends on the processor. They often have a different number of Cycles per Instruction. (http://en.wikipedia.org/wiki/Cycles_Per_Instruction)
Does a RISC processor have complex instruction sets each requiring several clock cycles for execution?
A pure RISC processor does not, however most modern RISC processors have high speed floating point arithmetic units (and sometimes other functional units) that do take multiple clock cycles for execution. Pipelines and out of order completion mechanisms are used to hide some of the effects of this.
How many machine cycles do one byte instructions have?
Depending on the particular microprocessor, a machine cycle is the fetch or store of one (typically, one byte) native word. In the 8085, this is a byte fetch or store, plus the overhead in decoding and processing the instruction. In this case, the first machine cycle is four clock cycles, or T states, and subsequent machine cycles are three clock cycles, although certain instruction sequences, such as DAD, require two extra clock cycles.
How many clock cycles will a 1.7 GHz computer have?
1.7 * 10^9 = Clock Cycles
What is CPU frequency?
There is insufficient information in the question to properly answer it. You need to specify which FPGA you are interested in. Please restate the question.
How do you change gigahertz in laptop?
The "gigahertz" reading of your laptop basically denotes the processor speed. It's the number of cycles occurring in your processor, each second. So, you have to change your processor to change your gigahertz. Some new processors have over-clocking features to increase (over-clock) your processor speed to a higher value (higher than it was designed to operate optimally). You might have to go for better cooling solutions for your processor, in case you plan to over-clock.
Does GHz represent processor?
No. It represents the clock speed of the processor. The clock speed is usually misinterpreted by many as the power of the processor, but the physical design of the processor has far more to do with the processors throughput than the clock speed itself.
What unit is a processer speed measured in?
The performance or speed of a processor depends on e.g. the clock rate and the Instructions Per Clock (IPC), which together are the factors for the Instructions per second (IPS) that the CPU can perform.So speed of processor can be measured by IPS alone.
What does 102.5 MHz represent?
One MHz represents one million cycles per second. The speed of microprocessors, called the clock speed, is measured in megahertz. 102.5 MHZ means 102.5 Million cycles per second that processor can work.
