Cache Coherency In Heterogeneous Systems

Until recently, coherency was something normally associated with DRAM. But as chip designs become increasingly heterogeneous, incorporating more and different types of compute elements, it becomes ...

Formally Modeling and Verifying CXL Cache Coherence (Imperial College London)

“We report our experience formally modelling and verifying CXL.cache, the inter-device cache coherence protocol of the Compute Express Link standard. We have used the Isabelle proof assistant to ...

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 ...

Adding Cache to IPs and SoCs

Cache memory significantly reduces time and power consumption for memory access in systems-on-chip. Technologies like AMBA protocols facilitate cache coherence and efficient data management across CPU ...

CXL: Coherency, Memory, and I/O Semantics on PCIe Infrastructure

Gain insight into the CXL specification. Learn how CXL supports dynamic multiplexing between a rich set of protocols that includes I/O (CLX.io, based on PCIe), caching (CXL.cache), and memory (CXL.mem ...
