OCTEON Fusion-M CNF75xx: Macrocell-on-a-chips
The CNF75xx family of processors is a full L1-L7 implementation supporting from high capacity picocells at 800 simultaneous users all the way up to multi sector macrocells with up to 3600 simultaneous users. Additionally, multiple OCTEON Fusion-M CNF75xx chips can be cascaded for even denser deployments or higher order MIMO. The CNF 75xx integrates highly optimized custom 64 bit MIPS cores and multiple VLIW DSP engines along with a host of hardware accelerators for the wireless modem pipeline, network processing and traffic shaping. This family is designed to allow system OEMs and operators to build next generation networks in both macrocell and Cloud RAN deployments while retaining the flexibility to evolve into the new 5G standard.
