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 ...

In the first part of this series on the proposed Cache Coherence Interconnect for Accelerators (CCIX) standard, we talked about the issues of cache coherence and the need to share memory across ...

A fundamentally new approach to cache coherence has been released -- the first in more than three decades. Whereas with existing techniques, the directory's memory allotment increases in direct ...

Managing a cache so that data are not lost or overwritten. For example, when data are updated in a cache but not yet transferred to the target memory or disk, the chance of corruption is greater.

In the rapidly evolving landscape of data centers, ensuring cache coherence in multi-host environments is imperative. The Compute Express Link (CXL) 3.0 specification introduces a robust mechanism ...

You hear a lot about cache coherency these days. In fact, at the recent Linley processor conference, no fewer than three companies announced new cache-coherent networks-on-chip (NoCs). The first cache ...

Moreover, cache coherence is an especially important protocol to verify. A cache-coherence bug could result in a silent data corruption that would disrupt system functionality. A formal tool for ...

In today’s digital economy, high-scale applications must perform flawlessly, even during peak demand periods. With modern caching strategies, organizations can deliver high-speed experiences at scale.

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, ...
