PCIE-IOBUS-LN64 (Linux SDK)

GPIO-BUS Linux 64bits: PCIe to General Pourpuse I/O Bus Bridge (PCIe target), Drivers, QSYS and Demo Sources.

The IOBUS IP is a dynamically reconfigurable asynchronous bus master designed by GEB Enterprise. It supports 8/16/32 Data Bus wide, external interrupts, either fixed latency or variable latency bus cycle.
 
The IOBUS shall be the bus used for communication between a master (the Pcie card) and an unspecified number of slaves.  The bus supports up to 32 Data bits, up to 8 bits address, 2 Chip Select (CS#), Read Enable(RD#), Write Strobe (WR#), Interrupt request (INT#) and an optional Wait signal (WAIT#).

The bus cycle timing can be defined by a control register, setup, hold and pulse width can be changed by user allowing bus cycle time from 48ns to 768ns with 16ns steps. Additional delay can be added by WAIT# signal.

The system includes VHDL source, QSYS design, command line demo source and executable, fpga loadable files (both EP4CGX15BF14C7N and EP4CGX30BF14C6N fpga).
