ARM Introduces New High-performance Microprocessor Core

CAMBRIDGE, UK –Apr. 30, 2002 –– ARM [(LSE: ARM); (Nasdaq: ARMHY)], the industry's leading provider of 16/32-bit embedded RISC processor technology, today introduced at the Embedded Processor Forum, San Jose, Calif., the ARM1026EJ-S™ microprocessor core, the latest addition to the ARM10E™ microprocessor family. The ARM1026EJ-S core is fully synthesizable and supports the ARM Jazelle™ technology for Java™ acceleration. The ARM1026EJ-S core will run at 325 MHz worst-case in a 0.13um foundry process, and is targeted at a broad range of applications, including network processing, automotive, embedded control, consumer entertainment, and wireless devices.

The ARM1026EJ-S core implements the ARM v5TEJ instruction set architecture and includes extensions of the ARM architecture, the Thumb® architecture, DSP and Jazelle technology. Support for the optional VFP10™ floating-point coprocessor and ETM10RV™ embedded trace macrocell is also included, making the ARM1026EJ-S core an excellent choice for complex and demanding applications. The ARM1026EJ-S core has been optimized using the EEMBC benchmark suites to deliver improved real-world application performance.

"The EEMBC benchmarks provide a valuable resource to help systems developers and CPU architects assess the impact of design choices on real world application performance," said Markus Levy, senior analyst of the Microprocessor Report and EEMBC president. "Through detailed performance analysis using the EEMBC suites, the ARM1026EJ-S core design team was able to incorporate several very beneficial features, such as improved branch prediction and sequential store merging, to increase embedded application performance."

"Next-generation applications running advanced operating systems demand greater CPU performance and design flexibility than ever before," said Eric Schorn, CPU product manager, ARM. "The ARM1026EJ-S core is the latest member of the ARM10E family and is designed to maximise application performance while also extending our well established lead in low power and system cost."

Additional features and support
The ARM1026EJ-S core offers support for configurable caches and tightly coupled memories (TCM), which result in lower die area and cost efficiencies, and vectored interrupt support to reduce interrupt latency and improve real-time performance. The ARM1026EJ-S core is delivered as synthesizable IP and offers considerable flexibility through configurable cache and TCM sizes, support for memory management units (MMU) and memory protection units (MPU). Extensive 64-bit on-chip interconnect allows for increased bandwidth which better addresses the implementation of complex applications, such as networking, with large data sets.

The ARM1026EJ-S core delivers over 400 Dhrystone MIPS at 325 MHz in a 0.13u foundry process. Extensive performance analysis using the EEMBC benchmark suites influenced the design choices made to increase embedded performance. The EEMBC scores for the ARM1026EJ-S core will exceed those of the ARM1020E™ core that ARM is publishing today on the EEMBC website.

Availability
The ARM1026EJ-S core will be delivered primarily as soft IP but hard IP is also available upon request. The core is available now for licensing from ARM.
