Some ideas/further suggestions:

  • check if the Timer Measurement code gets somehow "optimized" by the compiler and therefore does not match the one used in the call
  • maybe do some max|min evaluations on a number of testcases (low priority) [added to article 2007-07-31]
  • how to "invoke" the microcode expansion for FPU native calls (add problem description) [added to article 2007-10-04]

[edit] Nice to have

  • SimpCon ready count generated in sc_fpu for earlier restart of the CPU pipeline - we know the cycles from fpu.vhd
  • Get the FPU closer to JOP: attach input registers to A and B, provide microcode instructions for fadd, fsub, fmul, and fdiv
  • Correct the FPU error
  • Get the FPU smaller - there is some duplicated stuff (de/normalize)
