SoC design: When a network-on-chip meets cache coherency

Many people have heard the term cache coherency without fully understanding the considerations in the context of system-on-chip (SoC) devices, especially those using a network-on-chip (NoC). To understand the issues at hand, it’s first necessary to understand the role of cache in the memory hierarchy.

Co-Designed Cache Coherency Architecture for Embedded Multicore Systems

In this paper, we present the round-robin method applied to baseline coherency protocol and initial analysis of one hybrid protocol that performs speculative requests when access patterns are detected. We also propose to manage patterns through a dedicated hardware component attached to each core of the processor.
