We obtained the "official" Dhrystone V2.1 benchmark source code from http://www.netlib.org/benchmark/dhry-c and compiled and ran it. We converted the Dhrystone figure to DMIPS by dividing by 1757 which we understand to be the standard conversion.

On our OMAP 3525 running LynxOS SE at 500 MHz and compiling with LynxWorks cross compiler we get 237.1 DMIPS To compare we used an older board using the OMAP 3430 (that we used prior to 3525 availability) under Monta Vista mobile Linux and using their cross-compiler and got 258.7 DMIPS.

We realize that Dhrystone measurements will vary some due to differences in compilers and OSs but would not expect our getting around 25% of TI's figure.

Can you suggest why we might be getting such drastically lower figures?
