Virtualization for embedded systems has many implementations in which two or more operating systems coexist to gain the benefits of each. One approach puts Microsoft Windows and a Real-Time Operating System (RTOS) together.

Much is being said about virtualization these days in the softwareworld. Simply stated, virtualization is about getting multiple OSs to run on the same computing platform at the same time. Virtualization has been cited as a key technology for getting the most performance out of the newest multicore processors. But just as not all computing applications are the same, not all virtualization approaches are appropriate for all applications.

Embedded Systems have a key requirement that doesn’t normally apply to office and server computers: the need for deterministic response to real-time events. To support the requirement for determinism, embedded applications typically use RTOSs. Embedded applications also employ general-purpose OSs to handle operator interfaces, databases, and general-purpose computing tasks.

In the past, because OSs couldn’t successfully co-reside on computing platforms, system developers employed multiple processing platforms using one or more to support real-time functions and others to handle general-purpose processing. System designers that can combine both types of processing on the same platform can save costs by eliminating redundant computing hardware. The advent of multicore processors supports this premise because it is possible to dedicate processor cores to different computing environments; however, the software issues posed by consolidating such environments require special consideration. Combining real-time and general-purpose operating environments on the same platform (Figure 1) places some stringent requirements on how virtualization is implemented.

A Wi-Fi specification, (IEEE-802.11 a/b/g/n) is a commonly adopted technology for in-vehicle computer products. These are AP (Access Point) Mode and Station Mode for the Wi-Fi technologies. In general, the Wi-Fi module can only support Station Mode which allows user to connect to a local Access Point in range; however, acrosser has studied and reviewed numerous field applications and has took into consideration these results when the company designed their in-vehicle computer products, such as, the AR-V6100FL and AR-V6002FL. Acrosser Wi-Fi modules can support both AP Mode and Station Mode, allowing the user to switch mode during operation.

AR-V6005 & AR-V6100 support the optional GPS/GPRS/WiFi module inside one compact system, to fulfill the highly demand from telematic applications. In addition, acrosser In-Vehicle PC has excellent mechanical design to adapt high environment endurance that is certified to operate under Vibration 3G (follow IEC60068-2-64) and shock 50G 11ms (follow IEC60068-2-27), and fully compliant with in-vehicle computer application such as E -Mark Certification (E-13).
