Pittsburgh, PA — (press release excerpt) — TimeSys Corp. today announced the availability of TimeSys Linux GPL, a freely distributed, open source operating system for multiple embedded boards. Each version of the TimeSys Linux GPL is specifically designed for use with different embedded processor architectures including PowerPC, ARM, Super-H, and Pentium.

TimeSys Linux GPL is a full Linux distribution that includes everything needed to develop, deploy, and maintain an embedded platform, including a low-latency Linux kernel plus all required libraries, tool chains, utilities, drivers, scripts, and documentation, all distributed under the GNU General Public License (GPL).

TimeSys Linux GPL includes a full-featured preemptible Linux kernel, plus other components needed to support predictable, extremely low-latency response. The fully preemptible capabilities mean the kernel has bounded, mutex-based kernel locking with a new fixed priority scheduler, schedulable (meaning the developer sets the priorities) interrupt handlers, and schedulable extended interrupt handlers, including the IP stack.

TimeSys Linux GPL currently supports six of the most popular embedded architectures/boards . . .

• PowerPC — Embedded Planet's RPX-CLLF and Synergy's VGM5
  
• ARM — Cirrus Logic CDB 89712
  
• Super-H — Hitachi Solution Engine SH-3 and SH-4
  
• Pentium — any Pentium or Pentium-compatible PC

Additional ports to more leading boards are under development and will be released early next year.

For applications demanding true real-time performance, the TimeSys proprietary Linux/Real-Time modules can be added to TimeSys Linux GPL, resulting in greatly enhanced latency, responsiveness, and real-time capabilities. Additionally, TimeSys Linux/CPU and TimeSys Linux/Net offer the capability to reserve guaranteed CPU and network interface availability for critical applications, regardless of load or priorities.

In addition, TimeSys offers several tools which make it much easier to create predictable, robust applications using the TimeSys Linux product line. These include: TimeStorm, a Windows-hosted Integrated Development Environment with cross-platform capabilities for many target boards; TimeTrace, a Windows-hosted target platform event tracing visualization tool; and TimeWiz, a Windows-hosted real-time analysis and simulation tool.

TimeSys Linux GPL is now available for download at www.TimeSys.com.
