Right, AVR's are fast 8Mhz clock =3D almost 8MIPS!, most OP codes =3D 1 cycle 68HC11 has some really nasty OP codes taking as much as 41, 68HC11 running on = 8Mhz clock gives 2Mhz instruction rate, most OP codes are 4-5 so MIPS =3D = 2,000,000 / 4.5 =3D 450KIPS! 0.5MIPS, its slow! Very robust OP codes compared = to PIC, AVR is the best of both worlds. R. >> > balance I'd say the PIC is faster for "average" s/w.
