The CPU’s cache reduces memory latency when data is accessed from the main system memory. Developers can and should take advantage of CPU cache to improve application performance. Modern CPUs ...

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 ...

The development of caches and caching is one of the most significant events in the history of computing. Virtually every modern CPU core from ultra-low power chips like the ARM Cortex-A5 to the ...

A technical paper titled “Scalable Hierarchical Instruction Cache for Ultra-Low-Power Processors Clusters” was published by researchers at University of Bologna, ETH Zurich, and GreenWaves ...

In the early days of computing, everything ran quite a bit slower than what we see today. This was not only because the computers' central processing units – CPUs – were slow, but also because ...

Cache prefetching is what allows processors to have data and/or instructions ready for use in a fast local cache rather than having to wait for a fetch request to trickle through to system RAM and ...

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 ...

Since the 2.0 kernel release, Linux has supported a large number of SMP systems based on a variety of CPUs. Linux has done an excellent job of abstracting differences among these CPUs, even in kernel ...

Intel released a new CPU model this week, the Intel Core i9 7900X, which is the latest model to feature a new cache architecture that hardware experts believe it will make exploitation of side-channel ...
