AMD announced the server processor Opteron A1100, based on the architecture of Team ARM, and some time ago released a board for developers, based on these decisions.
So processors Opteron A1100 can include up to eight 64-bit cores ARM Cortex-A57, each pair of cores shares among themselves 1 MB cache second level. Crystal also includes 8 MB cache in the third level, with all caches support error correction (ECC). The only exception is the instruction cache, where the protection is less important . There is a two-channel 64-bit DDR3 memory controller with support for DDR4 and ECC, each processor can work with 128 GB of RAM. In the crystal embedded interfaces SATA 6 Gb / s (8 ports), two-port Ethernet (10GBASE-KR) and 8 lines PCI Express 3.0.
An important role in the device Seattle play coprocessors - cryptographic (Cryptographic CoProcessor, CCP) and systems management (System Control Processor, SCP). The first allows you to reduce the load on the main core at large cryptographic load operations like compression and decompression, encryption and decryption. SCP is based on the core Cortex-A5 and is actually a system on a chip inside the system-on-chip. One of the main reasons for the emergence of such an isolated parts - is the need to introduce into Opteron A1100 technology support ARM TrustZone.
