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 ...

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 ...

Cache, in its crude definition, is a faster memory which stores copies of data from frequently used main memory locations. Nowadays, multiprocessor systems are supporting shared memories in hardware, ...

The past decade or so has seen some really phenomenal capacity growth and similarly remarkable software technology in support of distributed-memory systems. When work can be spread out across a lot of ...

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.

Scaling processing performance beyond the frequency and power envelope of single core systems has led to the emergence of multi-core clusters. Data access management within such processing systems ...

One of the key challenges in chip multi-processing is to provide a programming model that manages cache coherency in a transparent and efficient way. A large number of applications designed for ...

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, ...

The more cores—or processing units—a computer chip has, the bigger the problem of communication between cores becomes. For years, Li-Shiuan Peh, the Singapore Research Professor of Electrical ...
