Functional Unit Descriptions
National Instruments MXI-3 ASIC
The MXI-3 ASIC, which contains most of the logic in the two-board
system, is a PCI master/slave device using the PCI-PCI bridge register set.
MXI-3 uses data queues to store data for transmission, and also uses data
queues to store received data waiting for access to the target PCI bus.
MXI-3 ASIC transmits data to the parallel-to-serial converters, and
receives data from the serial-to-parallel converters.
