The dynamic interplay between processor speed and memory access times has rendered cache performance a critical determinant of computing efficiency. As modern systems increasingly rely on hierarchical ...

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 ...

Necessity is the mother of invention, and advances in chip packaging are catching up to those in transistor design when it comes to working in three dimensions instead of the much more limited two.

Most of us have a pretty simple model of how a computer works. The CPU fetches instructions and data from memory, executes them, and writes data back to memory. That model is a good enough abstraction ...

Cache isn’t something PC gamers think nearly enough about. At least, that seems to be AMD’s thinking as of late. With the release of 3D V-Cache on the Ryzen 7 5800X3D, though, AMD just proved its own ...

AMD said Monday evening at Computex 2021 that it has evolved its chiplet architecture into 3D chiplets, specifically what it calls 3D V-Cache technology. By itself, the technology promises performance ...

[Editors' Note, March 2, 2023: Some scrutiny by Tom's Hardware and online commenters pointed out that our integrated graphics (IGP) testing numbers for the earlier Ryzen 9 7950X chip were unnaturally ...

Ahead of AMD’s Zen launch in early 2017, enthusiasts were clamoring for exciting progress in the desktop CPU market. While we saw GPUs gain tremendously from one generation to the next, every CPU ...

The Eden Prairie, Minn.-based vendor has moved from the proprietary processor and controller used in its existing products to dual Xeon processors, said Mike Stolz, vice president of marketing for the ...

After it restarts, unplug your Roku TV from the power outlet. This is key. Wait for about 60 seconds. This allows any electrical charge in the capacitors to dissipate, ensuring the cache is fully ...
