        "Virtual platform" runs Windows CE, RTOS concurrently on a single CPU

        [Updated Sept. 26, 2006] -- Jaluna will debut software that enables Windows CE and a real-time operating system (RTOS) to run concurrenty on a single microprocessor core, at next week's Windows Mobile and Embedded DevCon. The demo will show Windows CE and Mentor Graphics's Nucleus PLUS RTOS coexisting on top of Jaluna's OSware virtualization platform, all running on a single-core Texas Instruments...


        OMAP ARM9 processor, the company says.

        Update: Jaluna on Sept. 26, 2006 renamed itself to "VirtualLogix," and rebranded its OSWare product porfolio to "VLX." Additionally, the company began targeting specific market segments, beginning with three products aimed at helping companies lower costs and preserve legacy software investments while adopting Linux, including one targeting mobile phones.

        According to Jaluna, the trend toward embedded mobile connectivity requires "the consolidation of heterogeneous applications very often designed for different operating systems." For example, mobile phones typically are implemented with two OSes, one to handle the user experience, and one to manage the real-time requirements of the device's communications capabilities. By hosting both OSes on a single processor core, Jaluna reasons, companies can save critical costs in highly cost-sensitive mobile phone products. It also simplifies product development and speeds up time-to-market, the company claims.

        Jaluna says that its virtualization platform offers the same functionality to the embedded device space as similar technologies that have been deployed for years in enterprise IT. Using OSWare, a device-maker could, for example, use Windows CE in a single-processor mobile device without having to modify a legacy wireless protocol stack based on an RTOS such as Nucleus PLUS. As a result, operators and carriers can accelerate deployment of mobile handsets featuring Windows Embedded technologies on higher volume and lower cost phones, according to the company.

        In next week's demo, Jaluna will show OSware supporting Windows CE 4.2 (along with Nucleus PLUS). But OSware "should work as well [with] Windows CE 5.0," said Michel Genard, Jaluna's vice president of marketing and business development.
