Optimizing Energy At The System Level


Power is a ubiquitous concern, and it is impossible to optimize a system's energy consumption without considering the system as a whole. Tremendous strides have been made in the optimization of a hardware implementation, but that is no longer enough. The complete system must be optimized. There are far reaching implications to this, some of which are driving the path toward domain-specific c... » read more

Re-architecting Hardware For Energy


A lot of effort has gone into the power optimization of a system based on the RTL created, but that represents a small fraction of the possible power and energy that could be saved. The industry's desire to move to denser systems is being constrained by heat, so there is an increasing focus on re-architecting systems to reduce the energy consumed per useful function performed. Making signifi... » read more

Increasing AI Energy Efficiency With Compute In Memory


Skyrocketing AI compute workloads and fixed power budgets are forcing chip and system architects to take a much harder look at compute in memory (CIM), which until recently was considered little more than a science project. CIM solves two problems. First, it takes more energy to move data back and forth between memory and processor than to actually process it. And second, there is so much da... » read more

How Climate Change Affects Data Centers


Data centers are hot, and they may get even hotter. As climate change impacts temperatures around the world, designers are changing the computing hubs that are tied to nearly every aspect of modern life to make them more efficient, more customized, and potentially more disaggregated. These shifts are taking on new urgency as the tech industry grapples with months of sweltering temperatures o... » read more
