Dual-core designs make more of Windows
and RTOS
Using INtime and Windows on a dual-core processor gives a developer the benefit of a two box solution, without the complexity.
TenAsys Corporation now provides support for the new Intel Core Duo processor to meet demanding real-time Windows tasks Using INtime 3.0 and Windows XP, developers can dedicate one CPU core to real-time tasks and the other to Windows

The newest release of INtime will be demonstrated on both the Intel and Microsoft booths at Embedded World in Nuremberg, Germany.
Of significant benefit is the factor of ten decrease in timer interrupt latency for real-time Windows applications that use INtime on Intel dual-core processors.
The Intel Core Duo processors provide the computing resources of two processors in a single socket, at lower cost than a two box solution.
Using INtime and Windows on a dual-core processor gives a developer the benefit of a two box solution, without the complexity.
With one core dedicated to the INtime RTOS and the other to Windows, worst-case jitter is reduced to as little as 1-3us - a 10-fold decrease compared with an equivalent speed single-core processor.
The result is the ability to develop very precise, closed-loop control systems alongside the Windows operating system.
"The combination of INtime with the Intel Core Duo processor is a perfect example of how two execution cores in one processor package can be used to support simultaneous computing in embedded applications", says Rose Schooler, Director of Marketing, Infrastructure Processor Division at Intel Corporation.
"The TenAsys software environment allows developers to take two existing systems and migrate them into a single platform making it easier and more cost-effective to apply Intel Architecture platforms to real-time embedded applications".
In addition to vastly decreased timer interrupt latencies, a dedicated RTOS processor in a dual-core system is able to use 100% of the CPU cycles in its core.
Therefore, real-time tasks can maximise the number of compute cycles they consume without regard to sharing cycles with Windows.
This allows greater complexity in the algorithms that can be deployed, resulting in additional increases in the quality and performance of the control and data acquisition systems that can be implemented.
