formateur
Objectives
  • The course focuses on the internal interconnect architecture, based on the CSB bus.
  • Cache coherency protocol is introduced in increasing depth.
  • The 32-bit e300 core is viewed in detail, especially the MMU and the cache.
  • The boot sequence and the clocking are explained.
  • The course focuses on hardware implementation of the MPC837X.
  • A long introduction to DDR SDRAM operation is done before studying the DDR2 SDRAM controller.
  • An in-depth description of the PCI controller is performed.
  • The course highlights both hardware and software implementation of gigabit / fast / Ethernet controllers and the parameterizing of the level 2, 3 and 4 acceleration mechanisms.
  • The USB interface is also detailed.
  • The course explains how to initialise both the Serdes block and the SATA controller to detect and communicate with an external hard disk.
  • Generation of a Linux image and Root File System by using LTIB can also be included into the training.

  • This course has been delivered several times to companies developing telecom infrastructure equipments.
A lot of programming examples have been developed by ACSYS to explain the boot sequence and the operation of complex peripherals, such as SATA and Ethernet.
•  They have been developed with Diab Data compiler and are executed under Lauterbach debugger.
A more detailed course description is available on request at training@ac6-training.com
  • 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.
