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.
Founded in 1975 in Tokyo, Japan, eSOL is a leading embedded software developer with core technologies in real time operating systems. We develop, market and sell proven RTOS suites, along with a rich set of vertical oriented middleware libraries. Our rugged software development tools provide optimal reliability in backing up the highly complicated development process for RTOS-based applications. We know that a reliable RTOS and development tools make a significant difference to the quality and timeliness of our customers' products in a continuously growing and competitive world market. Today, our customers - global OEMs and ODMs ranging from consumer electronics to automotive applications - ship millions of products with technologies pioneered by eSOL.
