Leon: It is not realy a case of anything but comput intense applications. The application I am thinking about does between 100 million and 1 billion real multiplications per itteration. This takes on the order of an hour in 68882 instruction times at 25MHZ based on Motola data and the program takes around 3 to 5 hours when using FFP in TDI modula. I also do simulation programing which can take hours of computer time on any system. Also I frequently need the extra precision from double or even extended precision computation or the n'th generation data has no meaning. Gary Dunlap

TDI Modula-2 uses its own IEEE single-precision routines, it does NOT use the FFP library. Benchmark does use the FFP library and is therefore much faster at doing REAL operations. Give it a try… >> Leon Frenkel <<
