ARM Expands
ARM9 Family to Handheld Devices, NCs, Smart Phones and Windows CE
ARM910T and ARM920T add virtual memory support and
enhancements for Windows CECHICAGO,
March 31, 1998 -- ARM today announced the availability of the high-performance,
low-power ARM920T and ARM910T cores with virtual memory support for handheld devices,
network computers, smart phones and other processor-intensive applications. In addition,
the ARM920T incorporates new features and performance optimizations intended to enhance
the performance of systems using the Microsoft Windows CE operating system.
"The ARM920T and ARM910T processors are optimized for
high-integration designs that rely on feature-rich operating systems, like Windows
CE," said Carl Schlachte, ARM's VP of North America. "The ARM9 Microprocessor
Family is just another step on ARM's aggressive roadmap toward higher-end,
higher-performance cores."
The ARM9 Family builds upon ARM's current technology
offerings. Because the ARM9 Family is code-compatible with the highly popular ARM7 Family,
designers now have an even broader choice of CPUs to suit designs that range from
power-sensitive, high-performance applications to high-end, multiprocessing applications.
The ARM920T and ARM910T are cached processor macrocells built
around the ARM9TDMI core, which integrates a Thumb code decompressor. The ARM9TDMI
features a 5-stage pipeline and Harvard buses; the Thumb extension uses a compressed set
of 16-bit instructions, which reduces memory use by a third. The ARM9TDMI and ARM940T, as
the first members of the ARM9 Family, were announced in October 1997. The ARM940T is
targeted at embedded control applications which do not require virtual memory. All ARM9
Family members are process portable to 0.35µm, 0.25µm, and smaller geometries and
achieve 136 Dhrystone 2.1 VAX MIPS at 120MHz on 0.35µm. The ARM9 Family processors are
capable of delivering up to 220 MIPS at 200MHz typical, while only consuming 0.5 Watts.
The high performance of the ARM9 Family allows functions
previously performed by separate microcontrollers to be amalgamated onto one processor.
This lowers total system costs by reducing component cost, pin count and removing the need
to partition the design and provide for inter-MCU communication. The simpler system
architecture allows more rapid development, and the use of a single software development
environment for all code in the system. Examples of this trend include soft modems running
on the same processor as the main OS and applications in a handheld device, cellular
communications protocol stacks sharing the processor with application code in a smart
phone, and integration of previously disparate functions in set-top box designs.
ARM920T for Windows CE
The ARM920T integrates the superior performance of the ARM9TDMI core with the
power efficiency features for which the ARM Architecture is known. The ARM920T has
specific features and enhancements for the Windows CE operating system, making this an
ideal solution for emerging Windows CE-based applications, such as HPCs, network
computers, AutoPCs and sub-notebook computers.
"The announcement of the ARM920T - which supports the
Windows CE embedded operating system - is applauded by Microsoft," said Harel Kodesh,
general manager, consumer appliance group at Microsoft Corp. "With broad industry
support from companies such as ARM, Windows CE can be deployed in many new targeted
product categories supported by embedded systems. We believe the ARM920T will help
continue to spur the adoption of Windows CE across the widest possible breadth of
applications."
ARM910T for Handheld Devices and Internet
Applications
The ARM910T has a full MMU enabling the use of such feature-rich operating
systems as pSOS from ISI, VXWorks from Wind River and Psion Software's EPOC32. The virtual
memory features provided by the MMU make it possible to safely use code downloaded from a
network, such as the Internet, or from an independent developer. The ARM910T processor
cores are ideal for handheld devices, smartphones and Internet TVs.
Availability
The ARM910T and ARM920T are available now for licensing, for delivery in 2H98.
ARM9TDMI and ARM940T are also available for licensing. Silicon is available today from
selected ARM silicon partners. All ARM9 Family processors are process portable, and
implementations currently exist on 0.35µm and 0.25µm process technologies. Prices are
based on partners' specific system-level design implementations. Specifications are
preliminary and subject to change.
