eSOL Releases Further Blends on Multi-Core RTOS

-- Providing the Ultimate Optimization to Fully Utilize the Multi-Core Processor
while Keeping Deterministic Realtime Features --

Tokyo, Japan. October 3, 2007 - Following its debut at the ARM Developers' Conference last year, eSOL, a leading developer of realtime embedded solutions, today announced that the enhanced version of its realtime operating system, eT-Kernel Multi-Core Edition, is now available for ARM MPCore multi-core processors.

At last year's ARM Developers' Conference, eSOL introduced a one-of-a-kind RTOS that takes advantage of the capability of the ARM11 MPCore multi-core processor to support simultaneously both symmetric multiprocessing (SMP) and asymmetric multiprocessing (AMP). The eT-Kernel Multi-Core Edition supports two scheduling modes, True SMP Mode (TSM) and Single Processor Mode (SPM), that provide software developers with a blended multiprocessor RTOS. This provides software developers both the scalability and high throughput efficiency of SMP, with the more deterministic and realtime characteristics of AMP. All this is within a single tightly-coupled multiprocessor solution supporting POSIX 1003.1. 2004, T-Kernel/OS/SM/DS functions and T-Kernel Standard Extension APIs.

"The technical advances surrounding multi-core have progressed significantly over the last year and developers are desperately seeking better RTOSs and tools," says Nobuyuki Ueyama, the Executive Vice President of the Embedded Products Division at eSOL Co., Ltd. "Since its first release into the market last year, we have worked and collaborated with leading OEMs and ODM vendors to improve and fine-tune the RTOS. The enhanced eT-Kernel Multi-Core Edition is the result of such collaboration and our customer-oriented development philosophy."

The new release adds two new scheduling modes in addition to SPM and TSM. The added modes are also based on the eT-Kernel Multi-Core Edition's blended scheduling concept. SPMonTSM mode allows SPM behavior on TSM cores. Another mode, called SRLonTSM, provides serialization of specific groups of threads, while providing SMP scheduling among different thread groups. The new modes, just like the existing ones, can be specified on a per-thread basis, allowing all the scheduling modes to be blended in a single multi-core system, to provide optimized multi-core utilization.

Developers now have more scheduling mechanisms to choose from to fully optimize the overall system performance based on multi-core architecture. Coupled with the eT-Kernel Multi-Core edition is the eBinder integrated development environment. The eBinder IDE offers the industry's leading ARM® RealView® Compiler tool, along with comprehensive debugging and profiling tools to fine-tune the embedded application. It uses insightful snapshots of the eT-Kernel RTOS suites to help both firmware and application engineers easily identify glitches in programs and low-level drivers -- even in the multi-core environment supporting all four scheduling modes offered by the eT-Kernel Multi-Core Edition. The use of the eBinder IDE helps developers streamline development processes and increase overall productivity, ensuring timely product launch to market.
