Given:
Processor A clock frequency = 700 MHz
Processor B clock frequency = 900 MHz
Processor A instruction execution steps = 3
Processor B instruction execution steps = 5
To determine which processor is faster, we need to calculate the time taken by each processor to execute the same instruction.
Time taken by Processor A:
One clock cycle of Processor A takes 1/700000000 seconds = 1.43 x 10^-9 seconds
To execute one instruction, Processor A takes 3 clock cycles = 1.43 x 10^-9 x 3 = 4.29 x 10^-9 seconds
Time taken by Processor B:
One clock cycle of Processor B takes 1/900000000 seconds = 1.11 x 10^-9 seconds
To execute one instruction, Processor B takes 5 clock cycles = 1.11 x 10^-9 x 5 = 5.56 x 10^-9 seconds
Therefore, Processor A is faster as it takes 4.29 x 10^-9 seconds to execute the same instruction while Processor B takes 5.56 x 10^-9 seconds.
Hence, the correct answer is option A.
Processor A clock frequency = 700 MHz
Processor B clock frequency = 900 MHz
Processor A instruction execution steps = 3
Processor B instruction execution steps = 5
To determine which processor is faster, we need to calculate the time taken by each processor to execute the same instruction.
Time taken by Processor A:
One clock cycle of Processor A takes 1/700000000 seconds = 1.43 x 10^-9 seconds
To execute one instruction, Processor A takes 3 clock cycles = 1.43 x 10^-9 x 3 = 4.29 x 10^-9 seconds
Time taken by Processor B:
One clock cycle of Processor B takes 1/900000000 seconds = 1.11 x 10^-9 seconds
To execute one instruction, Processor B takes 5 clock cycles = 1.11 x 10^-9 x 5 = 5.56 x 10^-9 seconds
Therefore, Processor A is faster as it takes 4.29 x 10^-9 seconds to execute the same instruction while Processor B takes 5.56 x 10^-9 seconds.
Hence, the correct answer is option A.
