Concurrent Delivers High-Performance Linux Solution to Toshiba TEC for Next Generation Digital Multi-Function Peripherals.

Concurrent iHawk Powered by RedHawk Real-Time Linux Provides a Simulation Platform for Distinct Element Method

DULUTH, Ga. & TOKYO -- Concurrent (NASDAQ:CCUR), a leading provider of time-critical Linux[R] operating systems and integrated computer solutions for mission-critical applications, today announced that Toshiba TEC has selected Concurrent simulation technology for the development of its next-generation document processing systems. Toshiba TEC is a leading Japanese-based manufacturer of document processing, telecommunications and retail information systems.

Toshiba TEC chose a Concurrent iHawk solution running Concurrent's RedHawk[TM] Real-Time Linux[R] to assist in the development of new Multi-Function Peripherals (MFP), devices that perform a variety of functions such as copy, print, fax and scan. Toshiba purchased multiple iHawk high-performance PCI-based computer systems featuring AMD Opteron[TM] 64-bit processors. Their next-generation MFPs are developed using numerical model simulation. Distinct particle modeling will be used to analyze toner levels.

The Concurrent RedHawk solution simulates the behavior of more than 10,000 small toner and ferrite particles in a magnetic field. The required dynamic calculation interval is less than 100 nanoseconds and calculated for one complete revolution of a magnetic roller. The system helps determine design parameters such as particle size and distribution, roller speed, magnetic field strength with minimal experimental (laboratory) work.

"We needed to have the best high performance computing platform in place to simulate our new Multi-Function Peripherals (MFP) design," stated Koji Izawa, Vice President & Chief Technology Executive, Toshiba TEC. "We tested the Concurrent solution in depth and anticipate that the iHawk combined with integration services provided by Concurrent Nippon Corporation will reduce our MFP development costs while lowering the cycle time of our future product development for rapid time to market. Distinct Element Method under RedHawk Linux will be an important factor in the competitiveness of our future generation MFPs."

"Toshiba TEC is a great example of a leading electronics manufacturer that is working with Concurrent's iHawk and RedHawk Linux to benefit its consumers," said Osamu Nakamura, President of Concurrent Nippon Corporation, the Japanese arm of Concurrent. "We are pleased to be working with them and believe Concurrent's technology will have a great impact on the overall document processing experience of their customers as well as their return on investment in their next generation copiers," Mr. Nakamura added.
