What is next?

Need for novel computer architectures due to

e

mergence of new computing classes

emerging

challenges:

Looming end of Moore’s

law

“Power Wall” due to the end of

Dennard scaling (as transistors get smaller the power density no longer remains constant)“Memory

Wall” due to growing gap in performance metrics between memory and logic components

Bell’s law of computing classes“Roughly every decade a new, lower priced computer

class forms based on a new programming platform,network, and interface resulting in new usage andthe establishment of a new industry.” (Gordon Bell)

Will talk more about historical trends, challenges, economics at the end of quarter time permitted
