No, a microarchitect does not build tiny houses

portrait I am currently working at Microsoft Raleigh since December 2018: We are designing the control system of a Quantum Computer ("Ordinateur Cantique", en français chrétien).

Previously, I was at Qualcomm Datacenter Technologies Raleigh from January 2017 to June 2018 to work on future generation ARM microprocessors (Centriq). My work in the performance modelling group revolved — mostly — around efficient instruction delivery mechanisms.

Until 2017, and ignoring my 1-day tenure at Intel France as a research scientist, I was a research engineer with the PACAP INRIA research team at INRIA Bretagne Atlantique. My research focused on core microarchitecture and in particular, how to increase sequential performance. This included continuing the work I began during my Ph.D., i.e., revisiting a speculation technique that was introduced in the mid 90's: Value Prediction (VP).

VP has regained some traction recently as a way to increase sequential performance and may happen in future processors since Dennard Scaling has ended and Moore's Law is not doing too well. This might be why it was awarded the MICRO Test-of-time award in 2017. You might also be interested in the Championship Value Prediction.
