先来跑个分娱乐一下,工具为 Dhrystone BenchMark, Version 2.1,来源于 https://www.right.com.cn/forum/thread-196536-1-1.html
V1:
- Dhrystone BenchMark, Version 2.1(Language:C)
- system has 1 processor(s)
- DMIPSApp Running
- =====================================================
- Excution starts, 20000000 runs through Dhrystone(cpuNum=0)
- Execute ends(cpuNum = 0)
- ==========================================
- <font color="#ff0000">Total DMIPS:651.40</font>
复制代码 V3:
- Dhrystone BenchMark, Version 2.1(Language:C)
- system has 4 processor(s),I will fork 4 process,then adding together dmips,get total dmips!
- DMIPSApp Running
- =====================================================
- Parent process forked process 26265(cpuid=0)
- ....................................
- <font color="#ff0000">Total DMIPS:1421.45</font>
复制代码 从分数看上去V3比V1要高1倍以上,但是MT7621A是双核4线程?单核未必能跑的过QCA9563
