LOCAL_MEM_LOCAL_ADRS为物理内存的起始点,一般为0x00000000;

RAM_LOW_ADRS为vxWorks映像加载起始点;

FREE_RAM_ADRS为vxWorks映像加载结束点;

sysPhysMemTop( )为物理内存顶点;

sysMemTop( )为系统内存顶点,sysMemTop( ) = sysPhysMemTop () - USER_RESERVED_MEM;

FREE_RAM_ADRS+WDB_POOL_SIZE为system memory pool起始点,也即FREE_MEM_START_ADRS

WDB_POOL_SIZE = (sysMemTop()-FREE_RAM_ADRS)/16.
