True, but there was IIRC, a 32-bit version also. AMD calls 'em
microprocessors, but without so much as a P-counter, it's hard to justify
the name. Still, I wonder if a 5-package 2901 version without the carry
lookahead would be any faster than 2 trips (microprogrammed) through the
16-bit CMOS unit.
