The Intel386 DX Microprocessor is an entry-level 32-bit microprocessor designed for single-user applications
and operating systems such as MS-DOS and Windows The 32-bit registers and data paths support 32-bit
addresses and data types The processor addresses up to four gigabytes of physical memory and 64 terabytes
(2 46) of virtual memory The integrated memory management and protection architecture includes address
translation registers multitasking hardware and a protection mechanism to support operating systems Instruc-
tion pipelining on-chip address translation ensure short average instruction execution times and maximum
system throughput
The Intel386 DX CPU offers new testability and debugging features Testability features include a self-test and
direct access to the page translation cache Four new breakpoint registers provide breakpoint traps on code
execution or data accesses for powerful debugging of even ROM-based systems
Object-code compatibility with all 8086 family members (8086 8088 80186 80188 80286) means the
Intel386 DX offers immediate access to the world’s largest microprocessor software base
