ARM Introduces 2,000 DMIPS Cortex-A8 Processor

ARM has announced its new Cortex-A8 processor, which delivers up to 2,000 DMIPS while using less than 300 mW in 65nm technology.
The exceptional speed and power efficiency of the Cortex-A8 processor is enabled by new ARM Artisan libraries supporting Intelligent Energy Manager (IEM) technology and implementing advanced leakage control. The processor is supported by a wide range of ARM technologies for rapid system design including RealView DEVELOPER software development tools; RealView ARCHITECT ESL tools and models; CoreSight debug and trace technology; and software library support through the OpenMAX multimedia processing standard.

ARM has already secured five licensees for the Cortex-A8 processor, including Freescale, Matsushita, Samsung and Texas Instruments, and future support from major EDA and Operating System vendors.

The Cortex-A8 processor is the first applications processor based on the next-generation ARMv7 architecture, and features Thumb-2 technology for greater performance, energy efficiency, and code density. It includes the first implementation of the powerful NEON signal processing extensions to accelerate media codecs such as H.264 and MP3. The Cortex-A8 solution also includes Jazelle-RCT Java acceleration technology to optimize Just In Time (JIT) and Dynamic Adaptive Compilation (DAC), and reduces memory footprint by up to three times. Additionally, the new processor features TrustZone technology for secure transactions and Digital Rights Management (DRM), and IEM capability for low power.

The Cortex-A8 processor features an advanced superscalar pipeline which can execute multiple instructions at the same time and deliver more than 2.0 DMIPS per MHz. The processor integrates a size configurable level 2 cache which works in conjunction with fast 16K or 32K level 1 caches to minimize access time and maximize throughput. It uses advanced branch prediction techniques and has dedicated NEON integer and floating-point pipelines for media and signal processing. The Cortex-A8 processor will run at more than 600 MHz in low-power 65nm processes with the core using less than 4 mm of silicon (excluding NEON, Trace technology and L2 cache). High-performance consumer designs will run the Cortex-A8 processor at up to 1 GHz in high-performance 90nm and 65nm processes.

The ARM Cortex-A8 processor is available for licensing now, along with the majority of the supporting technology. First availability for the Advantage-CE library in leading 65nm technologies will be Q1 2006.


Crossware Coldfire Suite Builds Freescale's Trio MP3 Application

Crossware has released a new version of its ColdFire Development Suite which is able to build the Trio MP3 application software developed by Freescale Semiconductor.

Based on the Flex real time operating system, the Trio MP3 application runs on the ColdFire MCF5249 and SCF5250 microprocessors. It includes not only an MP3 decoder and encoder but decoders for Microsoft Windows Media Audio (WMA), Advanced Audio Coding (AAC), Ogg Vorbis and other format files. These files can reside optionally on a hard drive, CD drive or SD card.

Freescale supplies its Trio MP3 application as source code and a set of precompiled libraries. A set of 'makefiles' is also supplied which are used to control the compiler, assembler and linker during the build process. However, an enhancement to the Crossware Embedded Development Studio enables these 'makefiles' to be used to automatically create the files necessary for the application to be built from within Crossware's user friendly GUI development environment.

For example, the user has simply to browse to the folder containing the master 'makefile' and the Embedded Development Studio will create the completely configured development Workspace in less than 30 seconds. The application can then be immediately built, downloaded and run on the target board. Flash videos illustrating the Workspace creation, build and download process are available on the Crossware web site.


Freescale Introduces S08QG Family Low-End MCUs

Freescale Semiconductor has begun rollout of the new S08QG family with the MC9S08QG8/QG4 MCUs. Based on the HCS08 core, these new MCUs provide up to 20 MHz (10 MHz bus) at >2.1V operation for 100ns minimum instruction time and 16 MHz (8 MHz bus) frequency at <2.1V.

To deliver increased on-chip integration, the MC9S08QG8/QG4 MCUs add an enhanced 8-channel, 10-bit analog-to-digital converter (ADC) designed for better resolution, speed of conversion and low power. The onboard analog integration allows an easy interface to analog inputs with minimal external glue logic. The inclusion of a Serial Communications Interface (SCI), a Serial Peripheral Interface (SPI) module and Inter-Integrated Circuit (I2C) bus modules maximizes options for external components to interface with and enables increased design flexibility.

Flexible timer options allow for greater software flexibility with the 8-bit modulo timer module (MTIM), as well as motion control capabilities with the 2-channel Timer/PWM module (TPM). The combination of these components on a single chip reduces the need for external system components and can help decrease the overall system costs.

The 9S08QG8/QG4 also offers on-chip integration without compromising the low power consumption demands of many 8-bit applications, by offering a series of clock source options. The internal clock source (ICS) module provides an accurate, low-power internal clock generator, eliminating the need for and cost of an external crystal or oscillator. The 9S08QG8/QG4 MCUs are capable of supporting external clock source inputs from 32 kHz up to 20 MHz.

These new 8-bit microcontrollers are available for the suggested resale price of $0.89 (USD) for the MC9S08QG4 and $0.99 for the MC9S08QG8 for 1,000-unit MSRP on the least expensive package.

TI Begins Volume Production of TMS320F23x Controllers

Texas Instruments has announced volume production of its TMS320F2801, TMS320F2806 and TMS320F2808 digital signal controllers. Based on TI's DSP technology, these 32-bit controllers feature a highly integrated, control-optimized peripheral mix that includes a patent-pending PWM with 64 times higher resolution than the nearest competitor for faster control loops and quicker system response as well as more accurate control systems, making these controllers instrumental in applications ranging from digitally controlled power supplies and laser-based air and medical sensors to high performance, vector-based motor control.

With a DSP core and the C-language efficiency and ease-of-use of a MCU, F28x controllers offer 100 MIPS of 32-bit DSP performance. The ability to position the edge of a PWM signal with 150 ps precision or 16 bits accuracy in a 100 KHz control loop enables faster transient response and smaller ripple amplitude to eliminate "limit cycle" issues in digital power applications.

The F280x controllers integrate a number of peripherals including 128 kBytes of Flash memory, a 12-bit, 16-channel A/D Converter, 16 independent PWM channels, quadrature encoder pulse (QEP) and time stamping capture inputs for position sensing. This high integration enables a single F2808 device to control up to five independent three-phase motors simultaneously. A 32-bit wide data path ensures superior execution performance while mixed 16-/32-bit instruction achieves excellent code density. Key communication interfaces include multiple CAN, I2C, UART and SPI ports.

The TMS320F2801 controller is $4.95, the TMS320F2806 is $7.45, and the TMS320F2808 is $9.95, all in production quantities. Each device is automotive qualified and available in both a 100-pin LQFP and 100-ball BGA package.


TI Announces MSP430F20xx Family of Microcontrollers

Texas Instruments has announced that the newest MSP430F20xx low pin-count, ultra-low power MCU series will deliver a 500 nanoamp standby mode utilizing unique very low-power oscillator (VLO) technology. The VLO technology allows the MSP430F20xx MCU to be totally self-clocked in an ultra-low power standby mode with self-wakeup capability using no external components. This enables systems such as fire detectors or home thermostats to operate from the same battery for over a decade.

The 500 nanoamp standby is achieved with all device failsafe features active including zero-power brown-out reset (BOR) allowing both ultra low power and extremely reliable systems. Prior to VLO, designers had been forced to use external crystals or oscillator circuits to achieve ultra-low power standby. Using no external components, the VLO reduces systems component count and costs as well as reducing space.

The new MSP430F20xx MCUs offer a flexible clock system that allows fast operation of up to 16 MIPS with no external components using a digitally controlled oscillator (DCO). The DCO is fully programmable up to 16 MHz and stable over temperature and voltage with the ability to switch from standby to full operation in less than one micro-second. This allows applications to conserve power and use smaller, lower-cost batteries. If embedded real-time clock (RTC) function is required, the F20xx MCU can use a common 32 kHz crystal and achieve a standby mode of 0.7 microamps.

All F20xx devices operate from 1.8 to 3.6V allowing direct battery operation, and are available in a 14-pin footprint as small as 4 x 4 mm with 10 GPIO pins that include programmable pull-up/pull-down resistors that further eliminate external components. Designers can match their requirements to three pin-compatible F20xx MCU peripheral options that include an analog comparator for very cost-sensitive applications, 200 ksps 10-bit A/D Converter for real-time signal processing, or a 16-bit sigma-delta ADC for high-precision systems.

All devices include an enhanced watchdog timer for better reliability, a multi-function 16-bit timer and in-system programmable Flash that provide greater design flexibility and field upgrade capability. With 128 Bytes of RAM and a full-featured 16-bit RISC CPU, complete development in C and the re-use of existing MSP430 instruction set architecture libraries is supported. The MSP430F20xx also uses existing MSP430 USB-based tool chains.

The MSP430F20x3 and MSP430F20x1 MCUs are sampling now with full production scheduled for Q4 2005. The MSP430F20x2 MCUs will sample in Q4 2005 with production in early Q1 2006.
