        Windows XP real-time add-on targets Core 2 Duo

        Ardence Inc's real-time extension for Windows XP and XP Embedded has been validated to support Intel's new Core 2 Duo processors, the company announced today. RTX version 7.0, released in July, adds deterministic behavior to Windows XP-based systems that require a high level of performance and scalability,...


        according to the company.

        Ardence says it is working closely with Intel to add Intel-specific enhancements to both RTX and the Ardence software-streaming platform. This includes integration with both Intel Virtualization Technology (VT) and Intel Active Management Technology (AMT).

        Virtualization is a software technique that isolates operating systems and their applications from platform hardware resources and from each other. Each instance of an OS -- known as a virtual machine -- runs in its own partition. The virtualization software (known as a virtual machine monitor) manages OS requests and activities, shifting control of the hardware to each OS as required.

        Intel says its AMT combines platform-resident hardware with firmware, and uses "out-of-band" (OOB) communication for IT management access regardless of the state of the operating system or platform power. Based on OOB technology, AMT maintains access to and management of the platform, even when a platform is powered down or has a nonoperational OS, provided it is connected to both a network and standby power.

        According to Ardence, RTX applications can be configured to run in "dedicated" or "shared" mode on multi-core processors. In shared mode, one core handles RTX and Windows processing, and any remaining cores handle only Windows processing. In dedicated mode, one core is exclusively dedicated to the RTX application, leaving the remaining cores available for Windows and other less-time-critical applications. Ardence says this "dramatically reduces" the latency of real-time threads while preventing starvation of Windows XP threads that could occur on a single-core processor.

        A 30-day free trial download of RTX version 6.1 is available from Ardence's website, here.
