-
- The dBench utility provides diagnostics, benchmarking and 4x4 simulation
- in a single menu-driven package.

- ** DIAGNOSTICS **
- This section performs a comprehensive series of tests on the coprocessor
- after first identifying CPU and FPU type.
-
-
-
- ** BENCHMARKS **
- This section performs a varied series of floating point calculations. The
- tests are carried out twice, on the first pass, the coprocessor is given
- the calculations, on the second the coprocessor is ignored. An estimate
- of the improvement is finally given.
-
- NOTE:
- Some disk activity takes place during the benchmark tests. The benchmark
- calculations are carried out ignoring such activity (as they should be).
- The effect of this howvere is that if running from floppy disk the elapsed
- time of the test will be somewhat longer than the figure displayed. In
- order to minimise this effect it is recommended that the tests are copied
- onto your hard disk before starting.

-
- ** 4 X 4 **
- This section performs a simulation of the benefits to be gained by using
- the 4x4 microcode over attempting to perform a similar series of calculations
- by software. Some brief information on the 4x4 code is incorporated in
- the program, further information and the library modules and example
- source code are to be found in the directory F4X4.
