Episode notes
From BBC Micro Kid To Arm Fellow
- Geraint North described growing up with the BBC Micro and becoming the teacher's go-to when classroom computers broke.
- He traced a career from hobbyist to founding Arm's Manchester location and working on real-world customer problems.
Designing For A Multi-Year Horizon
- Arm must predict future workloads years ahead because silicon takes many years to reach products.
- That long horizon forces careful bets about which capabilities to include in CPU architectures.
Architecture Versus Implementation
- Arm licenses an architecture and lets partners build differentiated implementations and system-on-chip designs.
- This flexibility lets partners decide late-stage trade-offs like core counts and specializations for their markets.
