- Dhrystone 1.1 Benchmark

- For info contact me by email at dcc@dcs.ed.ac.uk, by post

- or see originator's name in file.
-
- This kit contains the source code for an old-ish version of Dhrystone,
- together with AmigaDOS executables, for 68000/noFPU and 68020/68881.
- It is intended for people who have systems on which Nic Wilson's
- "SysInfo" tester doesn't yet work properly, e.g. accelerated A500's
- and A3000/16's - it is not nearly as good a test, but should work on
- all Amigas, and since the code has been optimised, gives higher
- readings than the SysInfo Dhrystone code, useful for boasting to
- friends with other types of machine.
-
- The number of iterations, which has to be set by a #define in the
- source at compile time, is set to 500,000 - to get accurate readings
- for very fast machines (68040 etc.) it is advisable to increase it.
