LLC, positioned between external memory and internal subsystems, stores frequently accessed data close to compute resources.

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 ...

Part 1: A look at the impact of communication across multiple processors on an SoC and how to to make that more efficient. Managing how the processors in an SoC talk to one another is no small feat, ...

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 ...

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 ...

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.

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 ...

The shorter the distance application data has to travel to drive a web application, the better the user experience will be. Developers have a wide array of places to use a data cache, but each comes ...

As discussed in part one, one of the reasons cache coherency is becoming more important is the shared common memory resource in designs today. Various agents in the design want to access the data the ...
