NEC Unveils Industry's First Mobile Phone Application Processor with Parallel Processing Capabilities

Main Features of the MP211:

- Three ARM CPU cores and new software enable optimized processing for multiple mobile phone applications and offer higher performance. Compatibility with software previously used with single-CPU application processors minimizes development time.
- Linux OS platform offers greater flexibility and efficiency in software development, allowing development using open source software.
- Includes NEC Electronics' proven digital signal processor (DSP), with industry-leading sales of more than 160 million units in Japan, which allows optimal processing of multimedia applications via software. With this DSP, high performance applications such as terrestrial digital broadcast reception and videophone functions can be operated without accessing the hardware.
- New bus architecture allows the three CPU cores and the DSP to share just one memory unit, simplifying circuitry around the memory chip and enabling high speed data transfer, leading to improved performance compared to previous single-CPU architectures.
- Combination of above-mentioned multi-CPU and DSP technologies, together with low power consumption technologies, reduces power consumption by approximately 30 percent (for terrestrial digital broadcast reception and videophone operations, compared with single-CPU application processors).

"Parallel processing technology is a key to enabling enhancement of future applications, especially those that require both high performance and low power consumption," stated Yoshiharu Tamura, General Manager, Mobile Terminal Unit, NEC Corporation. "With the addition of the Linux operating system, we can expect greater usability and more efficient development."

Recently, mobile phone requirements have shifted dramatically from traditional functions such as standard calling and camera features, toward feature-rich functions such as videophone, animation and games, music playback, e-money, navigation systems, and terrestrial digital broadcast reception. In coming years, an even greater array of services is expected.

With these changes, hardware and software development for mobile phones has become increasingly complex, requiring greater resources. For mobile phone developers, it is critical to solution that simultaneously enables both high performance and low power consumption, while minimizing development time by ensuring backward compatibility with existing application software.

However, adding high performance functions such as image and audio processing to current single-CPU application processors results in higher CPU operating frequencies, which leads to higher power consumption and ultimately reduced talk time and standby time.

The MP211 application processor solves this dilemma by simultaneously providing higher performance and lower power consumption, and will be an integral part of NEC Electronics' lineup of solutions for the mobile phone space. NEC Electronics will demonstrate the MP211, as well as other new products, at CEATEC Japan 2004, beginning October 5th at Makuhari Messe.
