RI0 AXI3 / AXI4 INTERCONNECT

This course covers the AXI bus protocol, described in ARM AMBA v3 and v4

Objectives
  • This course details first the AXI3 protocol.
  • New signals present in AXI4 are then described.
  • The course explains the AXI4 stream protocol and indicates in which case this simplified protocol is suitable.
  • AXI4-lite protocol is described.
  • The NIC-301 interconnect IP is studied, clarifying synthesis options as well as software QOS parameterizing.
  • AXI Coherency Extensions (ACE) new channels are explained through an overall introduction to snooping.
  • The CCI-400 interconnect IP is described, highlighting the purpose of ACE-lite ports.
A more detailed course description is available on request at training@ac6-training.com
  • Knowledge of an interconnect, such as IBM CoreConnect or ARM AHB is recommended.
  • Theoretical course
    • PDF course material (in English) supplemented by a printed version for face-to-face courses.
    • Online courses are dispensed using the Teams video-conferencing system.
    • The trainer answers trainees' questions during the training and provide technical and pedagogical assistance.
  • At the start of each session the trainer will interact with the trainees to ensure the course fits their expectations and correct if needed
  • Any embedded systems engineer or technician with the above prerequisites.
  • The prerequisites indicated above are assessed before the training by the technical supervision of the traineein his company, or by the trainee himself in the exceptional case of an individual trainee.
  • Trainee progress is assessed by quizzes offered at the end of various sections to verify that the trainees have assimilated the points presented
  • At the end of the training, each trainee receives a certificate attesting that they have successfully completed the course.
    • In the event of a problem, discovered during the course, due to a lack of prerequisites by the trainee a different or additional training is offered to them, generally to reinforce their prerequisites,in agreement with their company manager if applicable.
