What is CE 6.0 ?

Windows Embedded CE 6.0 is NOTWindows Mobile 6.0

Windows Embedded CE 6.0 is…32-bit, real-time, multitasking OSHighly componentized

Delivered as a granular set of componentsUse CE 6.0 Platform Builder tools to configure image

ScalableFootprint scales with functionality selected

Wide variety of CPU supportRuns on x86, ARM, MIPS and SH4

And, will be the core of Windows Mobile…

Feeling the crunch.

Windows Mobile 5.0 = Windows CE 5.0 O/S

Same O/S Architecture since Windows CE 1.0

Maximum 32 Processes32 MB VM per processDLL “Cram” (Slot 1, 32MB)

Windows CE 5.0 System Calls

Application makes callPSL jump

Kernel Validates parametersMaps Service into Slot 0

Possible Cache Flush

CE 6.0 – New OS Layout

Supports upto 32K processes2GB VM Space per process!512 MB VM Shared DLL spaceMoving critical drivers, file system, and graphical window manager into the kernel

BenefitGreatly reduces the overhead of system calls between these componentsReduces overhead of all calls from user space to kernel spaceIncrease code sharing between base OS services
