Precomputing the remaining floating point operations.
...int is not only
difficult (due to the trigonometric functions etc) but may also degrade the
precision.
Here is an idea whereby we can easily precompute (record) all those values
on a powerful processor and then use (replay) them on an embedded processor
/ DSP. The only requirement is that 'xxx_init_xxx' should be called in
exactly the same environment in both cases (e.g. FIXED_POINT and with the
same mode or sequence of modes).
All that's needed is to include the code segment below in one of the .h
files and wrap all those float calculations in RECOPLAY, e.g. int sqrt2 =
RECOPLAY(sqr...
