Motorola's 68000 16-bit processor, introduced in 1979, was superior to the competing Intel 8086 processor because of its more advanced architecture
.6800 and had better memory segmentation and a 32-bit register divided into eight data and address registers
. The 68000 gave rise to a processor series called 680x0 which includes the 68010, 68020, 68030, 68040 and 68060 microprocessors. With the 68000s the virtual memory was introduced, a level 1 cache was integrated, as well as a memory manager (MMU) and the floating point unit (FPU).
