John joined ARM in February 2002 and took responsibility for their platform architecture. Today he is Director of Program Management focused on various programs around the application processor's technology roadmap including the definition and market development of the ARM MPCore multicore processor technology.
Prior to working at ARM, he specialized in enterprise software having worked for Microsoft for 5 years, firstly as Group Program Manager in the Exchange Server group and latterly as the manager of a team developing mobile phones software.
Graduating from the University of York with a BSc in Computer Science, John has over 20 years experience of realizing new technologies in the engineering industry.
In this talk, John will explore the technology and architecture introduced in the ARM Cortex-A15 processor in support of virtualization. This is the first of multiple processors from ARM that will support true virtualization, and the ability to host existing operating systems binaries without modification. The hardware extensions were defined following careful analysis to address the key virtualization performance limitations of today's solutions while bringing new technologies to the device to better support a virtualized system.
