EMBEDDED BENCHMARKS

Modern Education  |     |  

INTRODUCTION

  • It is the act of running a program, multiple programs in order to evaluate the relative performance of an object(an application) by running a set of standard tests against it.
  • It is an unique method for comparing the various subsystems across the chipset of an entire motherboard.
  • Commonly used software application uses databases or compilers to derive the results.

PURPOSE:

  • Just as the rapidly progressing complex architectural processors exists in the modern age so must a unique method to evaluate to compare the performance of each of these processors in various domains.

for eg:- Graphics, heating, 3d benchmark, frames per second(FPS)

CHALLENGES:

  • It’s not a piece of cake when it comes to benchmarking.It involves several repetitions tedious processes to come down to one final conclusion.
  • Often malpractices from other vendors can happen in the widely competitive world today in order to achieve their desired results and reputation.

TYPES OF BENCHMARKING:

 

  • Real programming:

 

  • A software tool of CAD
  • The word processing software
  • User’s application software
  1. Component benchmark:
  • Measures the computer’s basic performances of basic components.
  1. KERNEL:
  • Comprises certain keycodes
  • The produced results are presented in MFLOPS.

4. Synthetic benchmark:

  • They are of two types:-
  1. Whetstone
  2. Dhrystone
  • They were initially the first purpose benchmarks which however does not pull up big numbers for the widely popular modern pipelined computers.

Procedure:

          1.Initially take the stats from all application.

          2.Get proportion of each computation.

          3.Write a program based on the proportion above.

  1. Input/Output benchmarks
  2. The benchmarks for databases: Measuring response time and throughput(DBMS).
  3. Parallel benchmarks: Utilises multiples core/ processors or systems comprising of multiple machines.

COMMON BENCHMARK APPLICATIONS:-

1. Geekbench(3D performance checking)

2.ANTUTU(ARM devices testing app)

3.Sunspider(Web speed test)
