The SoC complies with SBSA Level 3 and SBBR (server base boot requirements) specifications, and supports EL3 secure memory and secure boot. There’s also a built-in Gigabit Ethernet port not shown in the block diagram, nor the specs, but mentioned in the product brief. CPU and I/O virtualization is also supported for running workloads and applications within virtual machines.

An Ampere Development Platform is also available with the following hardware and software features:

  • 19” chassis with an evaluation board featuring a built-in power supply, DRAM memory, storage disks and networking
  • Boot and Power management firmware
  • Arm Trusted Firmware (ATF)
  • AMI AptioV UEFI BIOS with support for all the device peripherals, VGA and a configuration GUI
  • CentOS Operating System
  • GCC and LLVM tool chains
  • AMI MEGARAC BMC firmware for baseboard management
  • Built-in support for workload accelerators
  • Documentation and collateral

The processors are sampling now, and mass production is schedule to start in H2 2018.
