- FOR IMMEDIATE RELEASE 20TH OCTOBER 1993 ARM 032

-
- ADVANCED RISC MACHINES ANNOUNCES THE ARM7 TECHNOLOGY
- HIGH PERFORMANCE WITH ICE AND DSP EXTENSIONS
-
- Advanced RISC Machines Ltd. (ARM), the Cambridge, UK headquartered designer
- and licensor of high performance, low power consumption 32bit RISC
- microprocessors, has announced its next generation of core technology at
- the Microprocessor Forum in San Jose, California. The announcement comes
- just two years after the launch of the ARM6 technology, which has achieved
- considerable success in a number of emerging consumer markets.
-
- In conjunction with its Semiconductor Partners, VLSI Technology, GEC
- Plessey Semiconductors, SHARP Corporation and Texas Instruments, ARM is
- announcing a family of products to be launched during 1993 and early 1994
- based around the ARM7 architecture. The ARM7 RISC CPU offers the user
- higher performance and reduced power consumption as well as both 3V and 5V
- operation.
-
- In addition the ARM7 offers system designers a range of optional
- architectural extensions to the CPU core which significantly improve the
- debugging of systems and digital signal processing (DSP) support.
-
- Target markets for the ARM7 family include the emerging application areas
- found at the convergence of consumer, computing and communications
- electronics. Examples include PDAs, interactive multimedia, advanced
- cellular phones, smart cards, ATM, virtual reality, automotive control and
- global positioning by satellite.
-
- In keeping with the "small is beautiful" philosophy of the ARM family, the
- compact ARM7 core contains just 35,610 transistors and measures 3.1mm x
- 1.9mm on a 0.8 micron 2-layer metal CMOS process. This offers users
- significant benefits in terms of ease of integration and low cost.
-
- Running at 20MHz on a 3V supply, the ARM7 consumes just 33mW at 1pF load,
- and at 33MHz on a 5V supply it consumes 165mW at 1pF load, making it the
- lowest power consumption 32-bit RISC architecture available on the market.
- It offers over 53k Dhrystone 2.1 (55k Dhrystone 1.1) at the higher speed
- (33MHz) and voltage (5V) and over 31k Dhrystone 2.1 (33k Dhrystone 1.1) at
- the 3V, 20 MHz operation. The ARM7 design has extended ARM's lead in
- balancing the conflicting requirements of high performance, low power
- consumption and small size, making it an ideal choice for the target
- applications that require these criteria.
-
- Additionally, the ARM7 core offers two extensions to meet the specific
- needs of particular users - embedded ICE (in-circuit emulation) capability
- and DSP functionality.
-
- The ARM7D is a core extension to ease the process of debugging systems by
- solving the problem of how to connect an ICE to a deeply embedded CPU
- without the need for any additional system hardware. The ARM ICE solution
- incorporates the ARM7D and the ARM ICEbreakerTM and BlackICETM devices to
- give complete ICE functionality within a fully integrated software and
- hardware environment.
-
- The ARM7DM offers, in addition to the ICE capability, DSP functions to
- enable users to run DSP-style applications at much higher speeds.
- Previously many DSP system designers adopted a dual processor approach -
- using both specialised DSP hardware as well as a general microprocessor for
- control purposes. The ARM7DM architecture combines both functions on a
- single device offering benefits in terms of cost, footprint and faster
- development cycle allowing rapid introduction of more competitive products.
-
- ARM7 family members will be launched in the oncoming months by ARM's
- semiconductor partners with the first ARM7 based product, the ARM700,
- available today from GEC Plessey Semiconductors. The ARM700 microprocessor
- combines the ARM7 core with 8 kbytes of cache, a Memory Management Unit,
- Write Buffer and a Coprocessor Interface running at up to 33MHz clock
- operation.
-
- Advanced RISC Machines Ltd (ARM) was founded in 1990 by Acorn Computers,
- Apple Computer and VLSI Technology. In April of 1993 Nippon Investment and
- Finance (NIF), a Daiwa Securities Company, became ARM's fourth investor.
- ARM designs and licenses high performance, low cost, low power consumption
- 32bit RISC processors for embedded control, computing, digital signal
- processing and portable applications. ARM also designs peripherals,
- supporting software and hardware tools. ARM has licensed its broad
- technology to four semiconductor manufacturers, (semiconductor product
- partners) VLSI Technology, GEC Plessey Semiconductors, Sharp Corporation
- and Texas Instruments. All manufacture and sell ARM products worldwide.
- ARM also provides design services, consultancy, feasibility studies, and
- training to its partners and key users of its technology. ARM's corporate
- goal is to become the volume RISC standard in the emerging market at the
- crossroads of communications, computing and consumer electronics.

- Sunday Times ARM7 article
-
- Cards to outsmart the fraudsters
-
- The successor to the British-designed microchip that drives Apple's
- Newton Personal digital assistant (PDA) is being launched in America
- next week by the British company Advanced RISC Machines - or ARM for
- short.
-
- Full details of the ARM 7 microprocessor will be revealed to delegates
- attending the Microprocessor Forum in Silicon Valley, California, on
- Tuesday, but the Sunday Times has been given an exclusive preview,
- writes John Stansell.
-
- ARM 7 will be up to twice as fast as the ARM 6, which is the heart of
- the Apple Newton. It is smaller and consumes less electrical power.
- Small size and low power needs combined with an advanced 32-bit
- processing architecture and high speed give ARM microchips a distinct
- edge in portable products that require long battery life - the reason
- Apple chose the ARM 6 processor for the first of its Newton PDAs.
-
- The new processor has a more advanced reduced instruction-set computer
- (RISC) 32-bit architecture, a geometry (the industry term for the width
- between the circuits on the chip) of 0.4 microns or millionths of a
- metre (ARM 6 is a 0.6 micron chip), consumes less than 1.5mA/MHz, and
- will operate from a 3V power supply compared with 5V for its
- predecessor.
-
- These attributes also provide the power and speed to unlock complex
- security when the processors are integrated on to smart cards.
- Fingerprint sensors will prevent bank-card fraud and the chips will
- eventually allow a card to recognise an authorised person's voice,
- handwriting, the shape of their hand or even scanning their retina to
- check their identity.
-
- The French company Gemplus is developing a smart card that can hold all
- the data relating to every detail of a person's credit cards in its
- memory, using the processing parts of the ARM chip to recognise
- fingerprints. Patrice Peyret, head of product development, says other
- chips suitable for smart-card use are based on 8-bit technology - 10 to
- 15 year-old designs that have been bottlenecks in the use of smart
- cards in financial applications where security checking is essential.
- The processing power required to unlock a typical security cipher
- within a second is way beyond 8-bit technology.
-
- "It would take such a chip about a minute", says Peyret. Although the
- volume producers of popular microchips have tried to boost the speed of
- their existing circuits by adding a fancy device called a "crypto
- coprocessor", this is like "putting turbo on a 2CV", he says.
-
- GEC-Plessy is another firm exploiting the ARM technology. It is
- developing a radio modem built into a type of card (known as PCMCIA),
- that would give machines, such as the Newton, the ability to link up
- with cellular networks without the need for any wired connection.
