1.3 66AK2H Device

The 66AK2Hxx (a.k.a. K2H) platform combines four Arm® Cortex®-A15 processors with up to eight TMS320C66x high-performance DSPs using the KeyStone II architecture. K2H device is optimal for embedded infrastructure applications like cloud computing, media processing, high-performance computing and so forth. The K2H has a five-port Gigabit Ethernet switch, with one port to host, and four Serial Gigabit Media Independent Interface (SGMII) ports connected to the networks.
