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 ...

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 ...

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 ...

Editor's Note: Multicore architectures find use across a diverse range of applications thanks to their performance and efficiency. By combining several general-purpose MCU cores — or MCU cores and ...

The CPU and the GPU share access to some pages of memory. New Linux code helps the kernel keep track of memory holding data for the GPU. The management of video hardware has long been an area of ...

Memory management on Linux systems is complicated. Seeing high usage doesn’t necessarily mean there’s a problem. There are other things you should also consider. Running out of memory on a Linux ...

We have described and applied a technique for selection of processor cache configurations for low power using a parameter defined as a product of the cache miss rate and cache size. 1. Introduction ...

Address Translation Services (ATS) is a mechanism in PCIe that allows devices to request address translations from the Input/Output Memory Management Unit (IOMMU). This is particularly important where ...
