User Guide
Figure 2–4 illustrates an example design with two Transceiver Reconfiguration
Controllers and four RapidIO II IP cores. In the example, Altera Transceiver
Reconfiguration Controller 0 has seven reconfiguration interfaces, and Altera
Transceiver Reconfiguration Controller 1 has four reconfiguration interfaces. Each
sub-block shown in a Transceiver Reconfiguration Controller block represents a single
reconfiguration interface. The example shows only one possible configuration for this
combination of RapidIO II IP cores; subject to the constraints described, you may
choose a different configuration.
Refer to Table 5–7 on page 5–5 for the values of N and M in Figure 2–4 .
f Refer to the "Transceiver Reconfiguration Controller" chapter of the Altera Transceiver
PHY IP Core User Guide for more information about the Transceiver Reconfiguration
Controller interfaces for Arria V, Arria V GZ, Cyclone V, and Stratix V devices and
how to control dynamic reconfiguration for multiple transceiver channels. Refer to
Table 5–7 on page 5–5 for information about the reconfig_from_xcvr and
reconfig_to_xcvr signals that connect a single RapidIO II IP core to multiple
Transceiver Reconfiguration Controller interfaces of the same Transceiver
Reconfiguration Controller.
