SMP Reference (Windows Embedded Compact 7)
Symmetric multiprocessing (SMP) uses a multiprocessor architecture where multiple processors are connected to a single main memory and are controlled by a single OS instance. In Windows Embedded Compact 7, the functions and variables for SMP are part of the board support package (BSP) data structures that are contained in the OEM adaptation layer (OAL) structures OEMGLOBAL and NKGLOBAL.
To enable SMP for your OS, set the IMG environment variable
IMGMPENABLE=1. For more information about this variable, see the IMG Environment Variables topic.
