Deterministic Linux

NetAcquire Deterministic LinuxTM (NDL) – Hard Real-Time Linux

The NetAcquire environment takes the work out of creating an embedded real-time Linux distributed system by providing all the fundamental hardware and software capability. You can concentrate only on the specifics of your application without needing to develop an entire system from scratch.

The NetAcquire Server Extension Toolkit allows programmers to develop customized extensions to the NetAcquire real-time Linux environment. These extensions leverage the full power of NetAcquire server capabilities, and allow the development of a finished application in a fraction of the usual time.

The NetAcquire Server Extension Toolkit reduces aerospace and test and measurement development risk by giving developers the ability to extend the industry-proven mission-critical NetAcquire system. Whether a small extension or a large custom subsystem, developers have an open-architecture path to ensuring that their final system meets all requirements.

The NetAcquire product real-time operating system ordering options offers full Linux API support combined with hard real-time performance. This allows NetAcquire software extensions to take advantage of the industry-standard APIs and third-party software libraries while still running in guaranteed real-time. Worst-case NetAcquire real-time performance is typically a factor of 500x better than desktop Linux or Microsoft Windows.

NetAcquire hardware and software components have been thoroughly tested for reliability and performance in mission critical applications. For example, one NetAcquire quality assurance test involves making and breaking millions of NetAcquire network connections to confirm network protocol reliability and long-term memory management. Since developers’ NetAcquire extensions are layered on the pre-qualified NetAcquire infrastructure, the overall testing requirements for the completed application are much lower while overall system reliability is higher.

The NetAcquire Server Extension Toolkit is ideally suited for OEM applications. Look for the Powered by NetAcquire™ logo on OEM products that use the NetAcquire Server Extension Toolkit to provide efficient and reliable real-time distributed computing.
