1 Dhrystone

The industry standard Dhrystone v2.2 is executed on one of the RISC-V CPU cores of the PolarFire SoC target platform. The Dhrystone suite remains intact with the application even after changing the wrapper code that allows different levels of execution timings on the PolarFire SoC Icicle kit. Dhrystone suite is adapted to get the processor performance, which plays an important role in the non-numeric system programming and emulates the processor usage with the help of certain common set of programs. The benchmarking value shows the iterations of the program executed by the processor at a particular time frame and normalizes to per MHz of CPU clock frequency.

The Dhrystone program gets the comparative performance differences between the external and internal memory settings along with the system settings. The Dhrystone suite features a well-structured code base, which takes full advantage of the wrapper code resulting in optimal biased configuration to get the best performance results.

Following are the key features of Dhrystone:

• Well-suited for embedded CPUs
• Provides great comparison of the compiler performances
• Performs synthetic benchmarks to compare different system architectures
• Has a very small binary footprint, which determines the CPU's benchmarking quickly
