In our last entry we discussed the value of using solid state disk (SSD) as a cache, which provides a simpler on-ramp to the accelerated world of SSD. With SSD cache there are no or limited changes ...

CPUs have a number of caching levels. We've discussed cache structures generally, in our L1 & L2 explainer, but we haven't spent as much time discussing how an L3 works or how it's different compared ...

A processor cache is an area of high-speed memory that stores information near the processor. This helps make the processing of common instructions efficient and therefore speeds up computation time.

Have you ever found yourself waiting impatiently for your Synology NAS to catch up with your demands—whether it’s loading files, running backups, or managing virtual machines? Many of us rely on NAS ...

Since the earliest days of microprocessors, system designers have been plagued by a problem in which the speed of the CPU's operation exceeded the bandwidth of the memory subsystem to which it was ...

Caches are increasingly common in DSPs, but many DSP programmers are unfamiliar with their operation. This article explains how caches work, using the two-level cache in TI's C64x as an example. It ...

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 ...
