Challenges and Innovations in Microprocessor Power Delivery

(56:50 + Q&A) -- multi-core microprocessors, 3D stacking, multiple power rails, current density, energy limits, system-in-package ...  Kaladhar Radhakrishnan, Intel Fellow and a Power Delivery Architect, Intel.  
Power delivery requirements for the early microprocessors were fairly rudimentary due to the relatively low power levels. However, several decades of exponential scaling powered by Moore’s law has greatly increased the power requirements and the complexity of the power delivery schemes. The breakdown in Dennard scaling in the mid-2000s has ushered in the multi-core era which has increased the number of cores ...
