GENERAL DESCRIPTION
user-defined instructions, using a coprocessor.
The P1750AE/SOS is a general purpose, single chip, 16-
bit CMOS/SOS microprocessor designed for high
performance floating point and integer arithmetic, with
extensiverealtimeenvironmentsupport. Itoffersavariety
of data types, including bits, bytes, 16-bit and 32-bit
integers, and 32-bit and 48-bit floating point numbers. It
provides 13 addressing modes, including direct, indirect,
indexed, based, based indexed and immediate long and
short, and it can access 2 MWords memory.
Thechipincludesanarrayofrealtimeapplicationsupport
resources, such as 2 programmable timers, a complete
interrupt controller supporting 16 levels of prioritized
internalandexternalinterrupts,andafaultsandexceptions
handler controlling internally and externally generated
faults.
TheP1750AE/SOSusesasinglemultiplexed16-bitparallel
bus. Status signals are provided to determine whether
the processor is in the memory or I/O bus cycle, reading
and writing, and whether the bus cycle is for data or
instructions.
The P1750AE/SOS offers a well-rounded instruction set
with 130 instruction types, including a comprehensive
integer,floatingpoint,integer-to-floatingpointandfloating
point-to-integer set, a variety of stack manipulation
instructions,highlevellanguagesupportinstructionssuch
as Compare Between Bounds and Loop Control
Instructions. It also offers some unique instructions such
as vectored l/O, as well as supports executive and user
modes,andprovidesanescapemechanismwhichallows
