Answer:
op shinchan doraemon and u
Answer:
35.155
Explanation:
N=1000 25% of N= 250 instructions require 4 clock cycles, 40% of N =400 instructions require 5 clock cycles, 35% of N=350 instructions require 3 clock cycles T = (N*S)/R = 250*4+400*5+350*3/1*109=35.155
A clock cycle in a computer is the interval between two oscillator pulses. The smallest unit of processor activity is carried out during a single increment of the central processing unit (CPU) clock. The clock cycle, which is regarded as the fundamental unit of measurement for how quickly an instruction may be performed by the computer processor, aids in estimating the speed of the CPU.
Clock tick is another name for a clock cycle. Each clock cycle was utilised to execute one instruction by the earliest CPUs and processors. Modern microprocessors, like the superscalar, can, thanks to advancements in technology, carry out several instructions in a single clock cycle. Most CPU operations require numerous clock cycles because only straightforward commands may be performed once every clock cycle. Some of the frequent clock cycle operations include load, store, jump, and fetch.
A processor's clock speed is expressed in hertz, or clock cycles per second. The clock speed of a CPU is measured in billions of cycles per second, or GHz.
