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 ...

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 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 ...

When talking about CPU specifications, in addition to clock speed and number of cores/threads, ' CPU cache memory ' is sometimes mentioned. Developer Gabriel G. Cunha explains what this CPU cache ...

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 ...

System-on-a-Chip (SoC) designers have a problem, a big problem in fact, Random Access Memory (RAM) is slow, too slow, it just can’t keep up. So they came up with a workaround and it is called cache ...

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 ...
