Microsoft® Windows Embedded CE 6.0 is a 32-bit, componentized open operating system designed to power small footprint devices and enable fast time to market for highly differentiated products. Windows Embedded CE is used in a wide variety of devices from Portable Media Players to Voice-over-IP phones. Why use ARM with Windows Embedded CE? Exclusive support and products, best-in-class features and over 10 years of partnership with Microsoft make ARM the leading Windows Embedded CE architecture: - Unique products - Windows Embedded CE-based Microsoft products such as Windows Mobile and Microsoft Auto are only available for the ARM processor architecture
- Hardware support – ARM has the widest range of silicon Partners supporting Windows Embedded CE and the broadest range of supported CPUs
- Software support – The majority of BSPs shipped by Microsoft are ARM-based
- Device Emulator – The Microsoft Device Emulator models an ARM-based virtual platform, providing software developers a fast, out-of-the-box environment that can run the same binaries as an actual device
- Hardware-assisted debugging - only available on ARM platforms, developed in close collaboration with Microsoft, the ARM RealView ICE eXDI2 solution enables debug that would be impossible with a pure software monitor approach
As an ARM partner, Microsoft has a page in the ARM Connected Community. Board Support Packages (BSPs) To accelerate ARM Partners' time to market, ARM offers example BSPs for our range of development boards, in addition to those already provided by Microsoft and other ARM Partners. Download ARM example BSPs for Windows Embedded CE. BSPs are installed on top of the Platform Builder, the IDE provided by Microsoft for building Windows Embedded CE. Vector Floating Point (VFP) Library To optimize for hardware architectures with a VFP unit ARM offers a VFP Library for Windows Embedded CE 6. The library replaces software emulated floating point instructions with hardware accelerated implementations. The VFP Library plugs into the Microsoft Platform Builder IDE to work with the Microsoft embedded tool chain. ARM VFPv2 library for Windows Embedded CE 6 Linking Bug Notice An issue has been found with the ARM VFPv2 library for Windows Embedded CE 6 that was previously accessible via these pages. While investigating a rounding error with modf() we found that the function tries to set appropriate rounding mode by calling _ctrlfp(). The ccrtfpw1.lib library provides a default implementation of _ctrlfp() and was accidentally linked with the FPCRT.dll (VFP) library. This default implementation never invokes _controlfp(), which sets the appropriate Rounding-Control bits in FPSCR. As a result, the Rounding-Control always remains in default state (Round to Nearest). Thus, for example, when a decimal value is greater than 0.5 in the case of modf(14.8), the values returned are 15 and -0.2, instead of 14 and 0.8. No other functions should be affected by this issue and we are currently in the process of removing the ccrtfpw1.lib from the FPCRT.dll library, which rectifies the issue. A new package will be available for download from these pages shortly. RealView® ICE eXDI2 driver The ARM RealView ICE JTAG-based debug interface connects to the Microsoft Platform Builder via an interface called eXDI2. This allows developers to communicate directly with the ARM processor, dramatically improving hardware visibility, enabling debug scenarios that are impossible with a software-based debug monitor, allowing direct control of the target device, and the examination and modifying of state. Available for general download from this site soon Key features Integrates the low-level debug capability provided by ARM RealView ICE with the advanced debug features of Platform Builder. Debug scenarios that are impossible with KITL: EBOOT, Kernel Initialization and interrupt routines Download and debug images without the need for a working Ethernet or USB Bootloader Enables viewing and modification of hardware state beyond Platform Builder's capabilities:
- Takes advantage of hardware breakpoints within the processor core
