Clock Frequency and Timer Calculations
The clock frequency determines the speed of all operations in a microcontroller.
Formulas
Clock Period = 1 / Frequency
MIPS = Clock Frequency / Cycles per Instruction
Timer Frequency = Clock / Prescaler
Prescalers divide the clock to create slower timer ticks, useful for generating precise time intervals without consuming CPU cycles.
हल किया गया उदाहरण
16 MHz clock, 1 CPI (ARM Cortex-M), prescaler of 64.
- 01Clock period: 1 / 16e6 = 62.5 ns
- 02MIPS: 16e6 / 1 = 16 MIPS
- 03Timer frequency: 16e6 / 64 = 250,000 Hz
- 04Timer tick: 64 / 16e6 = 4.000 microseconds
अक्सर पूछे जाने वाले प्रश्न
Does higher clock speed always mean faster execution?
Not necessarily. Pipeline stalls, memory wait states, and bus bottlenecks can reduce effective throughput.
What prescaler should I use?
Choose the prescaler that gives timer resolution suitable for your application while fitting the desired period within the counter range.
Why does my microcontroller run slower than the crystal?
Check for prescaler settings, PLL configuration, and wait states. Some MCUs divide the oscillator internally by default.
