CIM_MemoryMappedIO
The CIM_MemoryMappedIO class described in properties Table below addresses both memory and port I/O resources
for personal computer architecture memory mapped I/O.
Table 49. CIM_MemoryMappedIO Properties
Class Name:
CIM_MemoryMappedIO
Parent Class:
CIM_SystemResource
Property Description Data Type
CSCreationClassName See Common Properties of Classes string
CSName See Common Properties of Classes string
CreationClassName See Common Properties of Classes string
StartingAddress Identifies the starting address of
memory mapped I/O.
uint64
EndingAddress Identifies the ending address of
memory mapped I/O.
uint64
MappedResource Indicates the type of memory mapped
I/O. MappedResource defines if
memory or I/O is mapped, and for I/O,
if the mapping is to a memory or a port
space. Memory mapped I/O values
are as follows:
1- Other
2- Mapped memory
3 - I/O mapped to memory space
4- I/O mapped to port space
uint16
CIM_DMA
The CIM_DMA class described in DMA Properties contains DMA information. A DMA channel allows certain types of
data transfer between RAM and a device to bypass the microprocessor.
