Dhrystone
A short synthetic benchmark program by Reinhold Weicker weicker.muc@sni.de, weicker.muc@sni-usa.com, intended to be representative of system (integer) programming. It is available in ADA, Pascal and C.The current version is Dhrystone 2.1. The author says, "Relying on MIPS V1.1 (the result of V1.1) numbers can be hazardous to your professional health."
Due to its small size, the memory system outside the cache is not tested. Compilers can too easily optimise for Dhrystone. String operations are somewhat over-represented.

DMIPS是我最近才去深入了解的一个单位，以前看到都不求甚解了，汗一下...
D是Dhrystone的缩写，他表示了在Dhrystone这样一种测试方法下的MIPS，Dhrystone是一种整数运算测试程序。下面是在FOLDOC上的解释：DhrystoneA short synthetic benchmark program by Reinhold Weicker weicker.muc@sni.de, weicker.muc@sni-usa.com, intended to be representative of system (integer) programming.
