Ray say : Incpetions doesn't include real math coprocessor, but it
includes HCS08 Freescale CPU running @ 40MHz (core speed) with basic
math functions eg. multiply and divide.
8x8 multiply takes 10 cycles
16/8 division takes 12 cycles
16x16 multiply takes (routine) aprox 400 cycles (32 bit result)
32+48 add (par of MAC) takes 200 cycles
So, compare to c64 which runs 40x slower...
