The Military Intel386 microprocessor is an advanced 32-bit component designed for applications needing very
high performance and optimized for multitasking operating systems. 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, advanced multitasking hardware and a protection mechanism to sup-
port operating systems. In addition, the Military Intel386 microprocessor allows the simultaneous running of
multiple operating systems.
Instruction pipelining, on-chip address translation, and high bus bandwidth ensure short average instruction
execution times and high system throughput. The Military Intel386 processor is capable of execution at sus-
tained rates of between 3 and 4 million instructions per second.
The Military Intel386 processor 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 M8086 family members (M8086, M8088, M80186, M80286) means the
Military Intel386 processor offers immediate access to the world’s largest microprocessor software base.
