Windows Embedded CE 6.0

Windows Embedded CE 6.0 (codenamed "Yamazaki") is the sixth major release of the Microsoft Windows embedded operating system targeted to enterprise-specific tools such as industrial controllers and consumer electronics devices like digital cameras. CE 6.0 features a kernel that supports 32,768 processes, up from the 32-process limit of prior versions. Each process receives 2 GB of virtual address space, up from 32 MB. Windows Embedded CE is commonly used in supermarket self-checkouts and cars as a display. Windows Embedded CE is a background system on most devices that have it.

Windows Embedded CE 6.0 was released on November 1, 2006, and includes partial source code. The OS currently serves as the basis for the Zune HD portable media player. Windows Mobile 6.5 is based on Windows CE 5.2. Windows Phone 7, the first major release of the Windows Phone operating system, is based on Windows Embedded CE 6.0 R3; although Windows Phone 7 is also using Windows Embedded Compact 7 features.

New features

 * Some system components (such as filesystem, GWES (graphics, windowing, events server), device driver manager) have been moved to the kernel space.
 * The system components which now run in kernel have been converted from EXEs to DLLs, which get loaded into kernel space.
 * New virtual memory model. The lower 2 GB is the process VM space and is private per process. The upper 2 GB is the kernel VM space.
 * New device driver model that supports both user mode and kernel mode drivers.
 * The 32 process limit has been raised to 32,768 processes.
 * The 32 megabyte virtual memory limit has been raised to the total virtual memory; up to 2 GB of private VM is available per process.
 * The Platform Builder IDE is integrated into Microsoft Visual Studio 2005 as plugin (thus forcing the client to obtain Microsoft Visual Studio 2005 also), allowing one development environment for both platform and application development.
 * Read-only support for UDF 2.5 filesystem.
 * Support for Microsoft's exFAT filesystem.
 * 802.11i (WPA2) and 802.11e (QoS) wireless standards, and multiple radio support.
 * CE 6.0 is compatible with x86, ARM, SH4 (only up to R2) and MIPS based processor architectures.
 * New Cellcore components to enable devices to easily make data connections and initiate voice calls through cellular networks.
