Embedded microprocessors provide anti-lock and stability functions for the braking systems in your car, maintain high-speed communications links for connected electronics everywhere, and control the robotic systems that are increasingly automating our world. Demands for more affordable automation, more efficient engines and motors, and higher data rates are driving the development of these systems. However, the architecture and micro-architecture of such processors is affected by a more stringent set of constraints, compared to the more conventional application processors from Intel, AMD , and ARM ’s Cortex-A class. Such processors must have specialized features that facilitate security, fault-tolerance, and real-time responsiveness well beyond what is expected from a typical smartphone processor.

John Penton is a CPU Architect and Technical Lead at ARM , specializing in the development of such embedded processors. He has worked on a number of ARM Cortex-R processors that implement the ARMv7-R architecture and is currently leading the development of a new high-performance embedded core based on the ARMv8-R architecture. In this talk, John will discuss the differing constraints on these real-time processors compared to the more well-known applications processors and some of the architectural and micro-architectural features that result. The goal is to introduce aspiring computer architects to more unconventional constraints on processor development that may arise in industry, beyond performance, power, and area.

After the talk, John will be happy to take questions about the talk, as well as his career at ARM , and ‘life as a computer architect’, for attendees aspiring to careers in this field!

Food will be provided.
