IBM unveils dual-ISA core for mainframes, running ARM and z/Architecture natively

By PulseAugur Editorial · [1 sources] ·

IBM has unveiled its first dual-Instruction Set Architecture (ISA) core, capable of natively executing both ARM and z/Architecture instructions within the same core. This innovation, developed in collaboration with Arm and built on a 2nm process, aims to bridge the gap between traditional mainframe reliability and the vast software ecosystem of ARM, particularly for AI workloads. The new processor, expected in z18 mainframes, features 11 cores running at 5.7 GHz and includes enhancements for AI acceleration and memory. AI

IMPACT This dual-ISA core could streamline AI development and deployment on mainframes by allowing native execution of ARM-based AI software.
