Arm CoreLink Coherent Interconnects are highly configurable and scalable interconnects for multiple mobile computing use cases from energy efficient to high performance devices. They provide a fully coherent, system-level cache and snoop filter for improved energy efficiency and system performance.


At the end of this course, delegates will be able to:

  • Apply AMBA protocol knowledge to various system design decisions
  • Understand the configuration CoreLink of the CoreLink Coherent Interconnect
  • Configure and integrate a CoreLink Coherent Interconnect within their System on Chip
  • Develop code for CoreLink Coherent Interconnect address map programming
  • Debug CoreLink Coherent Interconnect simulations



  • Experience with coherent bus protocols and/or interconnects is helpful although not required
  • Basic understanding of Arm architecture memory types is helpful although not required



  • SoC / Interconnect architects designing the interconnect back plane / memory subsystem.
  • Integration and verification engineers who will need to configure and verify the functionality of the coherent interconnect
