Dhrystone-mips.
The "17-mips" AV100 gets something like 10-11 SPECinteger, 7-8 SPECfp.
Also, although it is perfectly legal, and DG documents it correctly,
something that doesn't show up in the unadorned numbers is the use of compilers
chosen on a benchmark-by-benchmark basis, i.e., either 2 different
C compilers are used for the 4 C benchmarks, or 2 different FORTRANs
for the 6 FP benchmarks, or both.  Again, this IS legal, but is why it's nice
to get the full-disclosure pages...
