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 ...
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 ...
A new technical paper titled “WARDen: Specializing Cache Coherence for High-Level Parallel Languages” was published by researchers at Northwestern University and Carnegie Mellon University.
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 ...
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 ...
Write-through: all cache memory writes are written to main memory, even if the data is retained in the cache, such as in the example in Figure 4.11. A cache line can be in two states – valid or ...
• Designed MSI, MESI and MOESI Coherence Protocols for a multiprocessor system. • Analyzed the Cache Performance for different cache configurations and different number of processors. • Modified the ...
Although snoopy virtual-bus approaches are the first step, hybrid snoopy-directory schemes will be the next trend in embedded coherence. Without a doubt, embedded systems-on-a-chip (SoCs) are becoming ...
