IM6 CSI-3

This course covers the Camera Serial Interface v3 (CSI-3)

formateur
Objectives
  • The course starts with an overview of MIPI specification.
  • Layers are described from bottom to top, starting with M-PHY, then UniPro and at last CSI-3.
  • The startup sequence and the procedure to enter / exit Hibernate state are explained.
  • Electrical characteristics of M-PHY are studied.
  • CSI-3 packet format is described, including both Attributes PDU and CSI-3 packet header.
  • The payload of image packet, including YUV, RGB and RAW data is explained, as well as raw data compression algorithms.
  • The course also covers the test modes.
  • Companies interested in attending this course must adhere to MIPI organization.
  • This course has been designed for engineers in charge of SoC architecture, functional verification or silicon validation.

A more detailed course description is available on request at training@ac6-training.com
