If you are familiar with the AMD Interlaken 150G core, note the following differences now found in the Interlaken 600G IP core.
- Maximum bandwidth has been increased from 150 Gb/s to 600 Gb/s.
- User LBUS interface is always segmented.
- Available segmented LBUS widths are 1024, 1536, and 2048 bits.
- Instead of 1 burst per cycle, now 2, 3, or 4 bursts per cycle are permitted, depending on the LBUS width.
- Some configurations only support BurstShort of 64 bytes.
- Some configurations only support BurstMax of 256 bytes.
- Some configurations now allow intermediate gaps in the LBUS (segments with
tx_enain= 0).
