Some Limits of Power Delivery in the Multicore Era


The ability to scale down threshold and hence supply voltages can no longer keep up with device density as technology scales. Microprocessor power density is therefore increasing. At the same time, the total number of C4s is predicted to be constant for the foreseeable future, according to ITRS 2011. As a result, more and more of the C4 pads are dedicated… (More)
