Our PCI bus measurement & control products conform to the latest PCI2.2 standards. They support plug and play (PnP) which can avoid manual setting of IO address, IRQ interrupt and DMA channel. Our design is an advanced PCI Core soft-core on FPGA, which realizes the PCI bus interface logic. It supports the control of master controllers and target devices. The PCI interface connects with DAQ controller directly; The DAQ controllers can support dynamic logic configuration through PCI Core, and the hardware functions can also be changed during operation.
