Memory Hardware Considerations for Windows Network Projectors (Windows Embedded CE 6.0)

1/5/2010

ROM and RAM requirements for Windows Embedded CE-based Windows Network Projectors depend on several significant factors, such as CPU selection, applications implemented, and performance considerations.

RAM

The Windows Network Projector software and the shell together require at least 64 MB of RAM. This requirement does not reflect the amount of RAM that is required for the graphics buffer or the OEM-supplied software. This memory requirement supports a Windows Network Projector running one or two RDP sessions. The recommended amount of RAM for a Windows Network Projector is 128 MB.

For execution of software on a Windows Embedded CE-based Windows Network Projector display, your hardware must have 32-bit wide SDRAM with a minimum frequency of 100 MHz. To provide a better user experience with smoother graphics output, use more SDRAM to buffer more graphics data. Additionally, using more SDRAM allows more applications to reside on the device.

ROM or flash

Windows Network Projectors require sufficient nonvolatile memory, such as flash memory or nonvolatile RAM, to store the operating system image, application software, universally unique identifier (UUID) and the registry entries that device settings. These devices require 32MB of ROM, plus user storage.

Additionally, the ROM must be sufficient to support software that you add to the network projector or display image. Microsoft recommends that you provide sufficient nonvolatile memory to store a minimal image backup as well as provide room for the registry to grow to at least 50 KB in size.
