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 ...

Until recently, an explanation of memory management would have amounted to a description of a computer’s virtual memory implementation. Now however, memory management encompasses organizing frequently ...

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 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 ...

The processors in today’s computers have grown tremendously in performance, capabilities and complexity over the past decade. Clock speed has skyrocketed, and size has dwindled, even as the number of ...
