A new technical paper titled “Learning Cache Coherence Traffic for NoC Routing Design” was published by researchers at Nanyang Technological University. “In this work, we propose a cache ...

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 ...

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 ...

Historically, memory coherence in multiprocessor systems was often achieved through bus "snooping," where each core was connected to a common multitier bus and was able to snoop on memory-access ...

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 ...
