ARM Ltd says its new Cortex-A8 applications processor will run at more than 600MHz in low-power 65nm processes with the core using less than 4mm? of silicon and enable next generation of advanced cell phones, media players and new portable devices requiring robust digital signal processing and control capabilities. High-performance consumer designs will run the Cortex-A8 at up to 1GHz in high-performance 90nm and 65nm processes.

The Cortex-A8 is ARM's first applications processor based on the next-generation ARMv7 architecture, and features Thumb-2 technology for greater performance, energy efficiency, and code density. Targeting next-generation mobile devices, the processor uses less than 300mW in 65nm technology, according to the company.

The processor features a superscalar pipeline which can execute multiple instructions at the same time and deliver more than 2.0 Dhrystone MIPS 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. The Cortex-A8 processor uses branch prediction techniques and has dedicated NEON integer and floating-point pipelines for media and signal processing.

The Cortex-A8 includes the first implementation of ARM's NEON signal processing extensions to accelerate media codecs such as H.264 and MP3. The Cortex-A8 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.

ARM has developed a full range of supporting technology around the new processor to reduce design time and accelerate time-to-market. This complete system solution includes development and debug tools, modeling technology and physical cell libraries. Included are the 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.

"The rapid convergence of digital entertainment and mobile communications technology requires new levels of system performance and security within a tight cost and power footprint," said Mike Inglis, EVP, Marketing ARM. "The new ARM Cortex-A8 processor and supporting technologies brings unprecedented levels of performance and energy efficiency to the home and mobile markets and will result in innovative new devices with media-rich applications coming to the consumer."

The ARM Cortex-A8 processor is available for licensing now, along with the majority of the supporting technology. Licensing fees were not available. ARM said it has already secured five licensees, including Freescale, Matsushita, Samsung and Texas Instruments, and future support from major EDA and OS vendors.
