Advanced RISC Machines announces
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.
the ARM7 Technology
with ICE and DSP Extensions
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
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
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
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.
