GENERAL DESCRIPTION
The UT1750AR (figures 1 and 2) is a high performance
monolithic CMOS 16-bit RISC microprocessor that supports
the complete MIL-STD-1750A Instruction Set Architecture
(ISA). Underlying the MIL-STD-1750A support is a high-
performance RISC that provides MIL-STD-1750A emulation
capability. Developed to provide effective real-time avionics
processing, the high performance of the native RISC machine
is available to the MIL-STD-1750A systems designer through
the MIL-STD-1750A Built-In-Function (BIF) opcode.
The UT1750AR is the first member of a family of high-
performance MIL-STD-1750 processors and support
peripherals from UTMC.
PRODUCT DESCRIPTION
The UTMC UT1750AR operates in its native RISC language
mode or MIL-STD-1750A ISA mode. As a MIL-STD-1750A
microprocessor, the UT1750AR requires 8K x 16 of ROM to
map the MIL-STD-1750A instruction set into the native RISC
machine language instructions. Each MIL-STD-1750A opcode
has a unique RISC code macro in the external ROM. The
UT1750AR executes the corresponding resident RISC code
macro to perform the MIL-STD-1750A instruction
requirements. When in this mode and operating with a 12 MHz
clock, the UT1750AR can throughput 600 KIPS using the DAIS
mix (800 KIPS @ 16 MHz).
The native RISC language mode is available to the user when
the UT1750AR is operating as MIL-STD-1750A processor
through MIL- STD-1750A’s Built-In Function (BIF) opcode.
When operating as a RISC processor, the UT1750AR executes
most RISC instructions in two clock cycles. Thus, a 12 MHz
operating clock frequency provides up to 6 MIPS of RISC
throughput (8 MIPS @16 MHz). This high execution rate, along
with its efficient architecture, make the RISC mode especially
effective in applications requiring real-time processing.
The architecture of the UT1750AR is based around 20 user-
accessible, 16-bit general purpose registers providing the
programmer with extensive register support. The UT1750AR’s
flexibility is enhanced by its ability to concatenate the 16-bit
registers into ten 32-bit registers. In addition, all registers are
available for use as either the source or the destination for any
register operation.
The UT1750AR fully supports multiprocessor, DMA, and
complex bus arbitration for managing the system bus and
preventing bus contention. Bus control passes among bus
masters operating on the same bus. The bus masters can be
several UT1750ARs or any other device requiring Direct
Memory Access, such as a MIL-STD-1553B interface.
The UT1750AR supports 16 levels of vectored interrupts. Ten
of these are external interrupts, eight of which are user-
definable. All 16 interrupt levels are prioritized and serviced in
order of priority.
When used as a MIL-STD-1750A microprocessor, the
UT1750AR’s instruction set supports 16-bit fixed-point single-
precision and 32-bit fixed-point double-precision data formats.
Also, the UT1750AR can emulate 32-bit floating-point and 48-
bit floating-point extended-precision data in two’s complement
representation.
In its native RISC mode, the UT1750AR’s three basic
instruction formats support 16-bit and 32-bit instructions. The
formats are Register-to-Register, Register-to-Literal, and
Register-to-Long-Immediate instructions.
Figure 3 shows the UT1750AR’s general system architecture,
its emulation ROM, instruction and data memory, and the
system interface. The emulation ROM is isolated from the
system; only the UT1750AR microprocessor accesses it.
