PCI Bus Core Target Controller Detailed Description
(continued)
Example: Target Write I/O
Figure 16 shows the timing on the PCI bus for a Target I/O write which is posted; that is, the operation completes on
the PCI bus immediately. The Target terminates the I/O write request by disconnecting with data on the first word,
thus disallowing bursting.
For a delayed Target I/O write, the initial access would terminate with a retry although the Target transaction has
been snooped and forwarded on to the FPGA application. Retry terminations will continue on all future accesses
until the FPGA application has finished processing the Target I/O write transaction. On the next access of this Tar-
get I/O write, the Target terminates the I/O write request by disconnecting with data on the first word, also disallow-
ing bursting.
The FPGA interface timing is as shown in Figure 18 and Figure 19 for dual- and quad-port respectively. The FPGA
interface timing is similar for Target I/O writes and Target single memory writes, and is described below in the
Single Target Write FIFO Interface section.
