5 CAN I/O Support for FIFO
5-42
Example 2
When looking at the time behavior of the model, you can observe that at each
millisecond 2 CAN messages are sent out via the FIFO Write block, while the
FIFO Read block reads each millisecond 3 events out of the receive FIFO. This
implies that one of the three events leaving the FIFO Read block will be of type
"No new event”. This can be visually shown, by attaching another FIFO Filter
block in parallel, which filters “No new events”, and then by displaying the
second output port, which reports the number of matching events. You can
display the model by typing, in the MATLAB command window, either
xpccanpcififo2.mdl or xpccan104fifo2.mdl.
Having observed this, we could then reduce the Read depth of the FIFO Read
block from 3 to 2. This would not change anything of the overall behavior of the
