■
Added new material on root port which is available for the hard IP implementation in
Stratix IV GX devices.
■
Changed to full support for Gen2 ×8 in the Stratix IV GX device.
■
Added discussion of dynamic reconfiguration of the transceiver for Stratix IV GX devices.
Refer to Table 5–29.
■
Updated Resource Usage and Performance numbers for Quartus II 8.1 software
■
Added text explaining where TX I/Os are constrained. (Chapter 1)
■
Corrected Number of Address Pages in Table 3–6.
■
Revised the Table 9–2 on page 9–2. The following message types Assert_INTB,
Assert_INTC, Assert_INTD, Deassert_INTB, Deassert_INTC and Deassert_INTD are not
generated by the core.
■
Clarified definition of rx_ack. It cannot be used to backpressure rx_data.
■
Corrected descriptions of cpl_err[4] and cpl_err[5] which were reversed. Added the
fact that the cpl_err signals are pulsed for 1 cycle.
■
Corrected 128-bit RX data layout in Figure 5–9, Figure 5–10, Figure 5–11, Figure 5–12,
