ns32008 microprocessor the original 32016 had 16-bit external databus, 24-bit external address bus, , full 32-bit instruction set. included coprocessor interface, allowing coprocessors such fpus , mmus attached peers main processor. mmu based on demand paging virtual memory, unusual feature compared segmented memory approach used competition, , has become standard how microprocessors designed today. architecture supported instruction restart mechanism on page fault, cleaner motorola approach dump internal status on page fault, had read back, before instruction continued. ns32016 microprocessor ns32081 fpu ns32032 microprocessor the first chip in series called 16032, later renamed 32016 emphasize 32-bit internals. became available in 1982, , may have been first 32-bit chip reach mass production , sale (at least according national semiconductor marketing). mc68000 released earlier instruction set allowing 32-bit operations, internal implementation 16-bit, 32-bit instructions take twice t...
