Name and Function
BUS HOLD ACKNOWLEDGE
output indicates that the 80376 has
surrendered control of its local bus to another bus master. See
Bus
Arbitration Signals
in Section 4.1 for additional information.
INTERRUPT REQUEST
is a maskable input that signals the 80376 to
suspend execution of the current program and execute an interrupt
acknowledge function. See
Interrupt Signals
in Section 4.1 for
additional information.
NON-MASKABLE INTERRUPT REQUEST
is a non-maskable input
that signals the 80376 to suspend execution of the current program
and execute an interrupt acknowledge function. See
Interrupt Signals
in Section 4.1 for additional information.
BUSY
signals a busy condition from a processor extension. See
Coprocessor Interface Signals
in Section 4.1 for additional
information.
ERROR
signals an error condition from a processor extension. See
Coprocessor Interface Signals
in Section 4.1 for additional
information.
PROCESSOR EXTENSION REQUEST
indicates that the processor
extension has data to be transferred by the 80376. See
Coprocessor
Interface Signals
in Section 4.1 for additional information.
FLOAT,
when active, forces all bidirectional and output signals,
including HLDA, to the float condition. FLOAT is not available on the
PGA package. See
Float
for additional information.
NO CONNECT
should always remain unconnected. Connection of a
N/C pin may cause the processor to malfunction or be incompatible
with future steppings of the 80376.
SYSTEM POWER
provides the

2.0 ARCHITECTURE OVERVIEW
The 80376 supports the protection mechanisms
needed by sophisticated multitasking embedded
systems and real-time operating systems. The use
of these protection mechanisms is completely op-
tional. For embedded applications not needing pro-
tection, the 80376 can easily be configured to pro-
vide a 16 Mbyte physical address space.
Instruction pipelining, high bus bandwidth, and a
very high performance ALU ensure short average

throughput. The 80376 is capable of execution at
sustained rates of 2.5–3.0 million instructions per
second.
and
high
system
The 80376 offers on-chip testability and debugging
features. Four break point registers allow conditional
or unconditional break point traps on code execution
or data accesses for powerful debugging of even
ROM based systems. Other testability features in-
clude self-test and tri-stating of output buffers during
RESET.
The Intel 80376 embedded processor consists of a
central processing unit, a memory management unit
and a bus interface. The central processing unit con-
sists of the execution unit and instruction unit. The
execution unit contains the eight 32-bit general reg-
isters which are used for both address calculation
and data operations and a 64-bit barrel shifter used
to speed shift, rotate, multiply, and divide operations.
The instruction unit decodes the instruction opcodes
and stores them in the decoded instruction queue
for immediate use by the execution unit.
The Memory Management Unit (MMU) consists of a
segmentation and protection unit. Segmentation al-
lows the managing of the logical address space by
providing an extra addressing component, one that
allows easy code and data relocatability, and effi-
cient sharing.
The protection unit provides four levels of protection
for isolating and protecting applications and the op-
erating system from each other. The hardware en-
forced protection allows the design of systems with
a high degree of integrity and simplifies debugging.
Finally, to facilitate high performance system hard-
ware designs, the 80376 bus interface offers ad-
dress pipelining and direct Byte Enable signals for
each byte of the data bus.
