Video controller 33
PCI-X interface
PCI-X bus technology is implemented for interfacing the video controller to the
Host. PCI-X is an enhanced PCI bus standard that doubles the speed and the data
exchanged between the system bus and the peripherals. The PCI-X bus is 64-bits
wide and runs at a bus speed of 100 MHz, providing a throughput of up to
800 Mbytes/sec. The PCI-X interface integrates a DMA write engine for direct
data transfer from local memory to Host memory. However, it does not support
master read transaction. Therefore, the Host must write data to the on-board
memory itself.
PCI-X to PCIe bridge
Matrox Vio Duo is a PCIe board. It connects to the 4x PCIe connector of a 4-lane
PCIe slot on the motherboard. PCIe is a high-speed serial transmission protocol
based upon the PCI bus standard. However, since Matrox Vio Duo implements
PCI-X bus technology to interface with on-board components, a PCI-X to PCIe
bridge is installed on the board to translate between the two protocols.
Flash EEPROM and CPLD
The video controller interfaces to a CPLD, which in turn interfaces to a 1 Mbyte
flash EEPROM.
The flash EEPROM stores:
• Board initialization parameters and board data.
• Configuration data for the acquisition section.
The CPLD generates a serial bitstream from data stored in the EEPROM, which
programs the video controller upon power-up.
