Cortex A57

Anyone loosely following AMD’s efforts with ARM intellectual property would have had on their periphery the noise of the A1100 product aimed at servers, codenamed Seattle. The idea was to use AMD’s back-end expertise to produce a multi-core ARM chip based on eight A57 cores for server and professional embedded systems, supporting up to 128GB of RDIMM memory and two 10GBase-KR Ethernet ports. The secret sauce of the processor is in the co-processors – a cryptographic one to offload dedicated acceleration of encryption/decryption or compression/decompression, and a system control co-processor that focuses on security and acts like a ‘processor within a processor’ with its own Ethernet connection, RAM, ROM and IO connectivity for remote management and sensing. The AMD A1100 – Steven’s piece last year...
