The KeyStone II architecture integrates an ARM Cortex-A15 processor quad-core cluster to enable Layer 2 (MAC/RLC) and higher layer processing. The external memory bandwidth has been doubled with the integration of dual DDR3 1600 EMIFs. MSMC internal memory bandwidth is quadrupled with MSMC V2 architecture improvements. Multicore Navigator supports 2× the number of queues, descriptors and packet DMA, 4× the number of micro RISC engines and a significant increase in the number of push/pops per second, compared to the previous generation. The new peripherals that have been added include the USB 3.0 controller and Asynchronous EMIF controller for NAND/NOR memory access. The 2-port Gigabit Ethernet switch in KeyStone I has been replaced with an 8-port Gigabit Ethernet switch and a 10 GbE switch in KeyStone II. Time synchronization support has been enhanced to reduce software workload and support additional standards like IEEE1588 Annex D/E and SyncE. The number of GPIOs and serial interface peripherals like I2C and SPI have been increased to enable more board level control functionality.
