Co-Designed Cache Coherency Architecture for Embedded Multicore 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 ...

Using OCP and Coherence Extensions to Support System-Level Cache Coherence

Open Core Protocol (OCP) [1][2] is a common standard for Intellectual Property (IP)core interfaces. OCP facilitates IP core plug-and-play and simplifies reuse by decoupling the cores from the on-chip ...

Heterogeneous Cache Coherence Requires A Common Internal Protocol

Machine learning and artificial intelligence systems are driving the need for systems-on-chip containing tens or even hundreds of heterogeneous processing cores. As these systems expand in size and ...

Formal Methodology Validates Cache-Coherence Protocol

Bugs in RTL code are problematic, but a bug in an architectural specification can be catastrophic. If the bug remains undetected until post-silicon debugging, the design process essentially starts all ...
