CarbonKernel RTOS simulator
(Last updated: Jul. 07, 2000)

CarbonKernel is a GPL-released real-time operating system (RTOS) API simulator that includes the first public release of a simulation model mimicking RTLinux, the popular real-time Linux add-on. The simulator allows tracing the execution of embedded software at source code level, and provides concurrent target debugging capabilities, UI simulation, and more.

What does CarbonKernel provide?

A RTOS simulation model (called a 'personality') stacked on top of CarbonKernel is able to provide an embedded application with a simulation of the original RTOS' API having the same functional behaviour than its "real world" counterpart. Simulating the RTOS behaviour in a host-based environment instead of emulating the machine code of the target platform has a lot of advantages: it's faster, does not require the cross-development tools, gives extended debugging, monitoring and tracing features and provides an easy way to stress the application under test with run-time situations otherwise barely conceivable on a real target.

Since the RTOS kernel is implemented by a simulation model, CarbonKernel can export as much information as you need concerning every system object's state, such as threads, semaphores, mutexes, queues and so on. In order to make the same information available the embedded RTOS running on a code emulator or the real target must have been specifically instrumented, which is not even always possible (source code availability for instance :o?).

CarbonKernel source and binary distributions are available at Sourceforge, here. The CarbonKernel main site is www.carbonkernel.org/. The CarbonKernel mailing list is carbonkernel@egroups.com.

FUEL Database on MontaVista Linux
Whether building a mobile handset, a car navigation system, a package tracking device, or a home entertainment console, developers need capable software systems, including an operating system, development tools, and supporting libraries, to gain maximum benefit from their hardware platform and to meet aggressive time-to-market goals.

Breaking New Ground: The Evolution of Linux Clustering
With a platform comprising a complete Linux distribution, enhanced for clustering, and tailored for HPC, Penguin Computing¿s Scyld Software provides the building blocks for organizations from enterprises to workgroups to deploy, manage, and maintain Linux clusters, regardless of their size.

Data Monitoring with NightStar LX
Unlike ordinary debuggers, NightStar LX doesn¿t leave you stranded in the dark. It¿s more than just a debugger, it¿s a whole suite of integrated diagnostic tools designed for time-critical Linux applications to reduce test time, increase productivity and lower costs. You can debug, monitor, analyze and tune with minimal intrusion, so you see real execution behavior. And that¿s positively illuminating.
