Getting Started With Blackfin Processors
1-27
Introduction
There are two versions of the Dhrystone benchmark. A deprecated version
(Version 1.1) contained some “dead code” that could be removed by opti-
mizing compilers. Version 2.1 corrected this and should be the version
used in practice (and is the one that is in the µClinux distribution). Some
manufacturers, however, still quote the (better) results of Version 1.1, so
care must be taken when comparing Dhrystone performance figures to
check which version was used.
