What is speed up in computer architecture?
In computer architecture, speedup is a number that measures the relative performance of two systems processing the same problem.
More technically, it is the improvement in speed of execution of a task executed on two similar architectures with different resources..
What is speedup in computer architecture?
Speedup- Speedup is defined as the ratio of performance for the entire task using the enhancement and performance for the entire task without using the enhancement or speedup can be defined as the ratio of execution time for the entire task without using the enhancement and execution time for the entire task using the May 14, 2023.
What is the formula for overall system speedup?
S m a x = 1 ( 1 − p ) + p s.
Amdahl's law formula calculates the expected speedup of the system if one part is improved.
It has three parts: Smax, p, and s.
Smax is the maximum possible improvement of the overall system..

What is the overall speedup if we make 80% of a program run 20 faster?
If 80% of the program is sped up by 20%, you will effectively reduce the runtime by: 0.8 * 0.2 = 0.16 .
So, your overall time will be reduced by 16%, which means your runtime will be 100% - 16% = 84% of what it was originally.
Your speedup is thus 1/0.84 = 1.19, which rounds up to 1.2..
What is the overall speedup?
The overall Speedup is the ratio of the execution time:- Proof:- Let Speedup be S, old execution time be T, new execution time be T', execution time that is taken by portion A(that will be enhanced) is t, execution time that is taken by portion A(after enhancing) is t', execution time that is taken by the portion that May 14, 2023.
- If 80% of the program is sped up by 20%, you will effectively reduce the runtime by: 0.8 * 0.2 = 0.16 .
So, your overall time will be reduced by 16%, which means your runtime will be 100% - 16% = 84% of what it was originally.
Your speedup is thus 1/0.84 = 1.19, which rounds up to 1.2. - The speedup is T/T'. (50/100x1/2) because 50% was enhanced by 2 times and same goes to the 4 times.
Let us hypothetically imagine that the execution of (2/3)rd of a program could be made to run infinitely fast by some kind of improvement/enhancement in the design of a processor.
