1 Software Development & Education Center Embedded Linux & Device Drivers

2 Embedded Linux & Device Drivers Introduction The course is designed for those who want to pursue Linux based Embedded Systems. Embedded Technology Training enables a student, a technologist or a hobbyist to develop microcontroller based systems the need of time is that engineer should equip with Embedded Technologies. This course of Embedded Linux is composed around ARM9 Microcontroller and Embedded Linux. This Course covers complete details about Linux kernel. Training will be given on ARM9 Development Board. It covers complete description of Embedded Linux, Programming, and Accessing of IO device. Various interfacing techniques like I2C, SPI, ADC, DAC, and USB are also discussed. So, utilize your talent with technology of present and technology of the future. EMBEDDED LINUX@ GLANCE Embedded Linux is the use of a Linux operating system in embedded computer systems such as mobile phones, personal digital assistants, media players and other consumer electronics devices, networking equipment, machine control, industrial automation, navigation equipment and medical instruments. According to survey conducted by Venture Development Corporation, Linux was used by 18% of embedded engineers EMBEDDED LINUXAPPLICATIONS

3 Course Description Module 1:- Linux Basics Introduction to Linux Linux basic commands Kernel classification (Monolith kernel and Microkernel) Kernel configuration and compilation GPL legal issues Module 2:- Linux kernel introduction Linux features Linux versions Linux kernel source Kernel configuration Module 3:- Process Management (kernel side) The Process Process Descriptor and the Task Structure Allocating the Process Descriptor Storing the Process Descriptor Process State Manipulating the Current Process State Process Context Copy-on-Write Forking vfork() Kernel Threads Module 4:- Process Scheduling Multitasking Linux s Process Scheduler Policy I/O-Bound Versus Processor-Bound Processes Process Priority Time slice The Scheduling Policy in Action

10 Skills Development Workshop Communication is something which all of us do from the very first day of our life, yet there is a question that haunts us most of the time Did I express myself correctly in such and such situation? The answer to this question is really tricky, because in some cases we leave our signatures and good impression but in some others we even fail to get our idea clearly. It happens mostly because we don t know how to act in certain situations. Every time we fail we don t lose completely, we do learn something, but prior knowledge of the same thing could be more beneficial because then we could have turned that failure into success. The course / workshop would focus at many aspects of personality, like: Building positive relationships with peers & seniors Building self-confidence & Developing clear communication skills Exploring and working on factors that help or hinder effective interpersonal communication Learning impacts of non-verbal behavior & Dealing with difficult situations and difficult people Workshops Consists of Following Activities: Personality Development Group Discussions & Debates Seminar & Presentations Case Studies & Analysis Corporate Communication HR & Interview Skills Management Games & Simulations Aptitude, Logical & Reasoning Assessments & Development Action Based Learning
