NetLogic's strategy of linking 4 quad-threaded, eight-core network processors instead of using a single 32 or 128-core processor has negatives and positives. The negative is that a 4 processor design will consume more power - because however optimum the Inter-chip Coherency interface, it takes additional power each time an access has to be done off-chip. The positives are that the design is versatile, and the same core architecture can be used for both low-end processing applications, as well as the high-end. In wireless infrastructure it could mean that this same architecture could be used for anything from pico base stations to macros. It also allows an OEM to have the same semiconductor and supply-chain strategy across different market segments, from wireless infrastructure to metro Ethernet to storage/security. This allows the advantages of software and hardware and engineering reuse.
