QED INTRODUCES RM5270 SUPERSCALAR 64-bit MICROPROCESSOR
RM5270 is the Third Member of QED's RM52xx Family and
is Targeted at
High-Performance Embedded Markets
SAN JOSE, Calif., Embedded Systems Conference, September 29, 1997
-- Quantum Effect Design, Inc. (QED), a leading supplier of high-end
embedded microprocessor solutions, today announced the most recent
addition to its RISCMark brand MIPS® architecture RM52xx™
microprocessor family - QED's RM5270™. The RM5270 joins the
RM5230™ and RM5260™ as the third product in the family
of R5000™ derivatives. The QED-designed R5000 is currently
shipping in high-performance systems including Silicon Graphics,
Inc.'s O2 workstation, Cisco's Series 7500 high-performance routers
and Electronics for Imaging Fiery printers.
The RM5270 represents the high-end of the RM52xx family with a
100 MHz capable 64-bit memory interface and integrated, on-chip
secondary cache controller. The RM5270 has also been designed
to offer customers a clear migration path to the RM7000™,
with full software and pinout compatibility. The RM5270 is ideally
suited for high-performance embedded control applications and,
like the other members of the RM52xx family and the R5000, the
RM5270 implements the MIPS IV Instruction Set Architecture (ISA)
and is fully backwards compatible with applications that run on
processors implementing the earlier generation MIPS I-III Instruction
Sets.
"The RM52xx family meets the requirements of many customers
who need either the superior data handling capabilities of a 64-bit
integer unit, or workstation-class floating-point performance
via a single-cycle 'Multiply/Add' instruction and superscalar
dispatch, or both, combined with support for different memory
architectures to meet system cost requirements," said Tom
Riordan, QED president and CEO. "The RM5270 extends the RM52xx
family with a 64-bit memory interface and on-chip L2 cache controller.
These features combined with a software and pinout compatible
migration path to the RM7000 allows customers the flexibility
to develop and/or maintain common software across multiple hardware
platforms to meet different price/performance points."
RM5270 Product Description
The RM5270 is a high-performance superscalar 64-bit microprocessor
with a 64-bit memory interface and integrated, on-chip L2 cache
controller with an estimated 5.0 SPECint95 rating, 5.2 SPECfp95
rating and 260 Dhrystone 2.1 MIPS performance at 200 MHz. It implements
a DSP-enhanced MIPS IV (ISA) that includes the "Multiply/Add"
(MULADD) and "Three-Operand Multiply" instructions.
Key features of the RM5270 include: superscalar instruction issue,
16KB instruction cache and 16KB data cache (both 2-way set associative
and lockable by set), full-featured MMU compatible with the R4600™,
R4700™ and R5000 microprocessors, high-performance 64-bit
memory interface with 100 MHz maximum operation,
5V tolerant I/O's and 1149.1 compliant JTAG boundary scan functionality
for manufacturing testing. The RM5270 is manufactured using leading-edge
0.35 micron technology and is available in a 304-pin Super-BGA
(SBGA) package.
The RM5270 is ideally suited for high-end embedded control applications
such as internetworking, high-performance image manipulation,
high-speed printing and 3-D visualization where its balanced integer
and floating-point performance and direct support for a large
secondary cache (up to 2MB) provide outstanding price/performance.
Tools Support for the RM5270
QED is supporting embedded designers' requirements with a wide
range of software and hardware tools for the RM5270 (see press
release "QED Expands Third-Party Tools Support for its High-End
Embedded Processors," September 29, 1997). Evaluation boards
are now available from Algorithmics, Ltd. (P-5064) and Cogent
Computer Systems (CMA-261). Compiler tool chain support is also
available from Algorithmics, Ltd. ("SDE-MIPS") and from
the Free Software Foundation.
Packaging, Availability and Pricing
Samples of the RM5270 are available now, with production volumes
scheduled for Q198. The RM5270 is available at 150 and 200 MHz
in a 304-pin SBGA package with prices starting below $75 in 10,000-piece
quantities.
QED's RM52xx Product Family
The RM52xx family provides workstation-class superscalar microprocessor
performance at an affordable price and is targeted at high-end
embedded applications such as internetworking, Windows® CE,
printers, games, Internet TV/set-top boxes/cable modems and other
high-speed communications devices.
The RM52xx family features a superscalar instruction issue architecture
that increases processor efficiency and performance. This architecture
enables one integer and one floating point instruction to be processed
within one microprocessor clock cycle, thereby achieving higher
system performance without increasing clock speed. Superscalar
processing is important for numeric algorithms found in DSP, imaging
and 3-D applications as it enables computation and operand access
to occur in parallel.
RM5230 and RM5260 Update
QED has added 150MHz and 175MHz versions of its RM5230 processor,
and 175MHz and 200MHz versions of its RM5260 processor to its
popular RM52xx product family. The company has also decreased
prices on these two processors by approximately thirty percent.
"The superior performance of the RM5230 and RM5260 have driven
higher volumes than we had initially anticipated, so this price
decrease reflects our desire to have our customers benefit from
these high volumes," said Riordan.
