One of the greatest challenges facing the designers of many-core processors is resource contention. The chart below visually lays out the problem of resource contention, but for most of us the idea is ...

The year so far has been filled with news of Spectre and Meltdown. These exploits take advantage of features like speculative execution, and memory access timing. What they have in common is the fact ...

In the eighties, computer processors became faster and faster, while memory access times stagnated and hindered additional performance increases. Something had to be done to speed up memory access and ...

The disk cache in OS X can sometimes use a fair amount of the system's RAM, and clearing it can help you figure out how much RAM your applications and system processes are using. Topher, an avid Mac ...

Cache memory significantly reduces time and power consumption for memory access in systems-on-chip. Technologies like AMBA protocols facilitate cache coherence and efficient data management across CPU ...

Many readers will be familiar with the idea of a glitching attack, introducing electrical noise into a computer circuit in the hope of disrupting program flow and causing unexpected behaviour which ...

Editor's Note: Demand for increasing functionality and performance in systems designs continues to drive the need for more memory even as hardware engineers balance the dynamics of system capability, ...

Several commands report on how much memory is installed and being used on Linux systems. You can be deluged with details or get a quick and easy answer, depending on ...

Multiple PC OEMs are selling laptops outfitted with Intel Optane cache drives -- but they're improperly combining that information in ways that makes it seem as if the Optane cache drive represents ...
