CorePCIF Target Function
CorePCIF Target Function
The CorePCIF Target function acts as a slave on the PCI bus. The Target controller monitors the bus and checks for
hits to the configuration space or the address space defined in its BARs. When a hit is detected, the Target controller
notifies the backend and then acts to control the flow of data between the PCI bus and the backend.
Supported Target Commands
Table 1-1 lists the PCI commands supported in the CorePCIF Target implementation.

I/O Read (0010) and Write (0011)
The I/O Read command is used to read data mapped into I/O address space. The I/O Write command is used to write
data mapped into I/O address space. In this case, the write is qualified by the byte enables.
Memory Read (0110) and Write (0111)
The Memory Read command is used to read data in memory-mapped address space. The Memory Write command is
used to write data mapped into memory address space. In this case, the write is qualified by the byte enables.
Memory Read Multiple (1100) and Memory Read Line (1110)
The Memory Read Multiple and Memory Read Line commands are treated in the same manner as a Memory Read
command. Typically, the bus master will use these commands when data is prefetchable.
Memory Write and Invalidate (1111)
The Memory Write and Invalidate command is treated in the same manner as a Memory Write command.
