This month's issue:
The first in a new line of RISC processors designed from the ground up to provide high performance at low cost, the ARM Cortex-M3™ delivers up to 1.2 DMIPS/MHz at clock frequencies up to 100MHz on a TMSC 180nm process. This is ARM's smallest package yet with just 33,000 gates. It also introduces a new Single Wire Debug interface, further permitting a reduction of device size and/or build cost. The powerful and efficient Thumb®-2 instruction set is utilized, and an optional memory protection unit (MPU) provides a privileged mode of operation for complex applications.
Other aspects of this design, which is based on a 3-stage pipeline Harvard architecture, create less power consumption and reduced memory requirements with tightly coupled system peripherals to maximize performance. Interrupt handling has been improved by implementing the register manipulations in hardware. The design switches between pending or higher-priority interrupts in only six cycles, and comes with 32 interrupt channels as standard but can be configured to between 1 and over 240 channels.
The ARM Cortex-M3 processor is available to license now with optional Embedded Trace Macrocell™ (ETM) technology. Completed deliverables including models, compatible RealView development tools, and synthesizable RTL will be released to ARM Partners by Q3 2005.
ARM and Handshake Solutions are collaborating on the development and marketing of a new ARM® processor using the low-power, self-timed Handshake technology. This new ARM processor is compliant with the ARMv5TE architecture and optimized for use in both synchronous and asynchronous system-on-chip designs, permitting easy integration by semiconductor makers. The key benefits of the processor include low Electro Magnetic emission, reducing the probability of interfering with sensitive circuitry, and low peak currents, reducing system power requirements. Because asynchronous processors consume zero dynamic power when there is no activity, they can significantly extend battery life.
The new ARM processor will be available as a licensable core from ARM in Q1 2005. It will be supported by Handshake Solutions' advanced design tools and methodology that enables customers to design a complete or partially asynchronous chip.
The AT91SAM7S32 and the AT91SAM7S64 are the first members of a series of small pin-count Smart ARM7 Microcontrollers (SAM7S-series) with Flash densities of 32kByte and 64kBytes, respectively. A 128kbyte and 256kbyte version, the AT91SAM7S128 and AT91SAM7S256, are planned for availability at the end of this year. The new 32-bit microcontrollers integrate a complete set of secure operation functions, including a watchdog clocked by an on-chip RC oscillator, power supply monitors and hardware protection of the Flash memory.
The AT91SAM7S series achieves single-cycle instruction access from embedded Flash at 27 MIPS. Its Advanced Interrupt Controller enhances the basic interrupt facilities of the ARM7 processor to give vectored priority interrupt handling in a minimum number of instruction cycles. Its hardware bit set and reset registers (another Atmel enhancement of the basic ARM provision) enable single-cycle bit manipulation, obviating the need for masked read-modify-write sequences.
The AT91SAM7S microcontrollers include a USB 2.0 full-speed port and a wide variety of communication and control interfaces including an 8-channel 10-bit ADC; DMA controller; a parallel I/O controller that multiplexes the peripheral I/Os with a set of 32 programmable general-purpose I/O lines; and an on-chip voltage regulator that allows single-supply operation at 3.3V.
In quantities of 10k, the AT91SAM7S32 is available in a 48-lead LQFP package at a suggested resell of $2.90 and the AT91SAM7S64 in a 64-lead LQFP package, at $4.05.

We reported about the Thinking Carpet already back in January 2004. Now Vorwerk Teppichwerke and Infineon Technologies AG presented, after two years of research work, the prototype of an electronically networked, high-tech carpet for the first time from 19th to the 23rd of October at the international “Orgatec“ trade fair in Cologne, Germany. Targeting office buildings the partners hope that the “Thinking Carpet” will soon take over functions implemented today with discrete sensor controls, such as alarm, climate control, regulatory or guidance systems technology.
Pressure sensors in the carpet report for example an alarm as soon as people enter a security zone. Software analyzes the signals to trigger an alarm, for example, only when movement was detected on a window or an emergency exit, but not at free-access entrances. Security zones can be individually defined and individually controlled on a time-frame basis. As soon as registered signals are additionally relayed to a security control centre, the point of alarm (break-in or fire) can be localized precisely in a matter of seconds. Pressure sensors in the carpet can also be utilized as door-openers and light switches, or as electronic counters for people.
In combination with shatterproof LEDs, the “Thinking Carpet” becomes a controllable guidance system: Llight-emitting diodes in the carpet mark the shortest route to an emergency exit. The combination of different sensory functions (pressure, temperature and motion) can additionally enable the detection of people lying motionless on the floor, triggering a call for emergency help.
A self-organizing network of robust microchips is responsible for the capturing and processing of data in the “Thinking Carpet”. If a sensor fails for some reason, the neighboring processors can use their own positioning to look for a new connecting route which circumvents the defective region and maintains functionality. This makes it possible to cut the carpet, replace segments or add new ones at any time. The sensors involved are built into a textile material, the so-called secondary backing layer of the carpet, and are linked to one another via fine wires. Depending on the desired dispersal of detected signals, a “Thinking Carpet” carries from one to 25 sensors per square meter in its backing.
Great attention is paid to safety: The special backing construction eliminates any danger of injury, even if the carpet is damaged. If the carpet comes into contact with wetness, an intelligent safety system assures that a short circuit does not render the entire intelligent network useless. Wet areas are automatically shut off, then put back into operation after they have dried.

The new MSP430F2xx family features a real-time clock standby mode of less than one micro-amp with the ability to switch in less than one micro-second to a fully synchronized 16 million of instructions per second (MIPS) active mode. Additional enhancements of MSP430F2xx, which reduce the need for external components, include an integrated +/- 2.5% on-chip oscillator, pull-up/pull-down resistors, and increased number of analog inputs. The in-system programmable Flash has been improved with smaller 64-byte segments, programming times as fast as 17 micro-seconds per byte and a lower 2.2-V programming voltage allowing the elimination of external EEPROMs in most systems.
The new family also features a zero-power brown-out reset (BOR) function, a new failsafe clock system, enhanced watchdog timer and improved bootstrap loader (BSL). In the event of a crystal failure, from active or any low-power mode, the MSP430F2xx clock system can automatically re-start the on-chip oscillator and force a non-maskable interrupt. External crystal connections are filtered to prevent external noise from being introduced to the system. The watchdog timer prohibits software from disabling its clock source, and errant code will force a complete system reset. Code security is improved with a hack-proof BSL that executes a complete memory erase after receiving an incorrect password.
First devices of the MSP430F2xx family will feature 1KB to 8KB Flash memory, up to 128B to 256B RAM, 16 I/Os, and a seven-input analog comparator. The MSP430F2xx devices will be available in volume production in first half of 2005 and will be priced starting from $0.89 in 10,000-piece quantities.
