Cavium Processor Complex

ATCA-9305 User’s Manual (10009109-07)

The main features of the CN5860 include:

The CN5860 and switch route packets using SPI-4.2 and control information flow using PCI.

The CN5860 has two SPI-4.2 interfaces with each one supporting up to 16 ports. Two high-

speed SPI-4.2 Altera (Stratix™ GX) FPGAs function as the SPI-to-XAUI bridge for each processor

to switch complex. The PCI interface supports up to four ports, consequently a total of 36 ports

can be supported internally by each CN5860.

3.1.1 Cavium Memory Map

Although the Cavium processors are 64-bit, the ATCA-9305 uses a 49-bit implementation.

Refer to the Cavium Networks OCTEON Plus CN58xx Hardware Reference Manual for more

detailed information on the memory map.
