Summary
👤
Senior🎓
Top SchoolAlex Hornung is a Senior Principal CPU Design Engineer based in Cambridge with over five decades of experience designing high-performance memory systems and CPU microarchitectures. At ARM he leads memory system and MMU architecture for little A-class cores, has shaped cluster-level cache and DSU explorations, and contributed to the AMBA 5 CHI coherent interconnect. His background spans instruction-fetch microarchitecture for both single-threaded and multi-threaded cores, coupled with technical assessment of successive DSU generations. An MSc in System-on-Chip (Distinction) and a First Class BEng in Electronic Engineering underpin a career that blends deep academic grounding with hands-on silicon-focused design. Unusually for an architect at this level, he has also contributed to open-source DevOps tooling—enhancing a Puppet module for Docker—to streamline build and init workflows, reflecting a pragmatic interest in system integration beyond core CPU design.
