LSI Logic Delivers Power and Performance Improvements for ARM7 Thumb
Core And OakDSPCore Brand 1660 Core - 09:17 a.m. Oct 28, 1998 Eastern
MILPITAS, Calif., Oct. 28 /PRNewswire/ -- LSI Logic
Corporation (NYSE: LSI) announces a performance and power
savings enhancement of its 32-bit, synthesizable ARM(R)7
Thumb processor core and 16-bit, fixed point OakDSPCore(R)
brand processor core. Two versions of each core have been
created in LSI Logic's G11(TM) (0.18-micron Leff) process,
one optimized for performance, the other for power savings.
The ARM7 Thumb core and OakDSPCore brand core, part of
LSI Logic's CoreWare(R) library, together form ideal solutions
for digital cellular handsets and also address applications such
as V.90 Modems, servo controllers for DVD players, PDAs
and other portable devices.
With LSI Logic's G11 process the ARM7 Thumb processor
will operate at speeds up to 100 MHz at 2.5-Volts, nearly
doubling the architecture's performance over the previous
version in G10(R) technology while the OAKDSPCore brand
processor will operate at speeds up to 80 MHz at 2.5-Volts, a
60% performance increase over the G10 version. The
power-optimized ARM7 Thumb processor and OAKDSPCore
brand processor operating at 1.8V consume less than
1mW/MHz, realizing a 50% reduction in power.
"The ARM7 Thumb processor and OakDSPCore brand
processor are proven technologies that our customers rely on,"
explains Giuseppe Staffaroni, vice president and general
manager of LSI Logic's Communication Products division.
"Strengthening and enhancing the performance of these cores
fortifies our leadership position in the wireless market and
helps our customers continue to differentiate and expand their
product offerings through use of LSI Logic's CoreWare
expertise," he added.
The ARM7 Thumb core contains a 32-bit RISC engine, thumb
code compression, low-power static design, on-board Booth's
multiplier and built-in debug features. The core is supported by
a wide array of development tools and real-time operating
system (RTOS) created and supported by ARM, Ltd. and third
party independent software vendors (ISVs).
The OAKDSPCore brand core consists of a central processing
unit, including a full-featured bit-manipulation unit for barrel
shifting and bit field operations. The core also has a clock
control unit, which allows the core's master clock to be
programmed, allowing additional programming flexibility. The
OakDSPCore brand core supports in-circuit ScanICE
debugging through the serial test scan chain and is tailored for
high-speed digital signal processing algorithm execution.
Support for the source code and system level development is
provided through a comprehensive set of tools, including an
assembler, C-compiler, simulator, emulator and evaluation
board.
The ARM7 Thumb core and the OakDSPCore brand core are
complemented with a complete set of building blocks
simplifying the development of the CPU subsystem. The cores,
in conjunction with LSI Logic's process technology, advanced
design methodology, extensive on-chip memory capabilities,
mixed signal options, CoreWare design program and the
industry's broadest package choices, raise system-on-a-chip
capabilities to an unprecedented level.
LSI Logic's Communication Products Division provides
leading silicon solutions for customers in the networking,
public networks and wireless communications market places.
In 1997, the Communication Products Division made up 32%
of the company's revenue.
