3.2 PCI-3488 Block Diagram
ADLINK PCI-3488 has 1KBytes on-board FIFIO to maximize the
data transfer rate. Its state-of-the-art state machine in CPLD coor-
dinates the data flow between PCI controller, FIFO and GPIB bus.
Figure 3-2: PCI-3488 Block Diagram
The FIFO can buffer data from master (either from PCI controller
or external device) when target is busy. Therefore the efficiency
will be significantly improved when transferring large block of data.
