Coremark

from Wikipedia, the free encyclopedia

CoreMark is a benchmark for measuring the performance of CPUs , mainly from the embedded area. It was developed by the EEMBC to establish an industry standard. The software is written in C and includes implementations of the following algorithms : list processing (finding and sorting), matrix operations , state machines and CRC .

motivation

The motivation behind CoreMark is to create a generic and scalable benchmark that is available for a large number of systems. It should be more complex and less synthetic than Dhrystone , but more portable to embedded systems than SPECint . Established companies in the embedded market such as ARM support the benchmark.

rating

The CoreMark allows a large number of systems to be compared, not only covering the embedded area, but also desktop and server systems. The problem, however, is that the hardware manufacturers can optimize compiler settings, which makes it difficult or almost impossible to compare the results of different system architectures.

Results

CoreMark results can be searched and viewed on the CoreMark website. The results have the following format:

CoreMark 1.0: N / C [/ P] [/ M]

  • N number of iterations with seed
  • C compiler version and flags
  • P parameters such as B. for data and code allocations
  • M - type of parallel execution (if used) and number of contexts

Example: CoreMark 1.0: 128 / GCC 4.1.2 -O2 -fprofile-use / Heap in TCRAM / FORK: 2
