32-bit, 33 MHz PCI Target Interface Core

The main PCI-T32 Interface core purpose is to isolate the user from having to solve complex problems of the PCI interface implementation and let the user instead focus on the application development.

The PCI-T32 Interface supports 32-bit address/data bus and operates up to 33 MHz (66 MHz optional) PCI clock frequency. It is fully compliant with the PCI Local Bus Specification, Revision 2.3.

The PCI-T32 Interface is a Target–only PCI Interface core. The interface implements 64 bytes of PCI Configuration Space registers. It is possible to extend the Configuration Space up to 256 bytes if required.

The Target supports up to six Base Address Registers with both I/O and Memory space decoding from 16 bytes up to 4 GB.

The Target supported commands are:

Configuration Read, Configuration Write
Memory Read, Memory Write, Memory Read Multiple (MRM), Memory Read Line (MRL), Memory Write and Invalidate (MWI)
I/O Read, I/O Write
This core can be mapped to any any Intel, Lattice, MicroSemi, or Xilinx programmable device, or to any ASIC technology, provided sufficient silicon resources are available.
