Modern multicore systems demand sophisticated strategies to manage shared cache resources. As multiple cores execute diverse workloads concurrently, cache interference can lead to significant ...

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 ...

Though computers store all data to be manipulated off-chip in main memory (aka RAM), data required regularly by the processor is also temporarily stored in a die-stacked DRAM (dynamic random access ...

In a computer, the entire memory can be separated into different levels based on access time and capacity. Figure 1 shows different levels in the memory hierarchy. Smaller and faster memories are kept ...

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 ...

Lag on a Roku TV rarely arrives out of nowhere. It usually builds up as temporary files pile on, apps misbehave, and the system’s limited memory gets squeezed until every menu tap feels sticky.

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 ...

System-on-chip (SoC) architects have a new memory technology, last level cache (LLC), to help overcome the design obstacles of bandwidth, latency and power consumption in megachips for advanced driver ...
