ARM Cortex A57 - System design

(ref.005012A)

4 days - 28 hours

Objectives

  • This course takes an in depth look at the considerations you will need to take into account when designing a system containing a Cortex-A57 processor core
  • It is aimed at :
    • Software engineers who not only want to obtain details of how to write software to run on the Cortex-A57, but also wish to obtain an understanding of hardware design issues
    • Hardware engineers who need to understand how to design Cortex-A57 based systems, but also wish to obtain an understanding of the issues of writing software to run on that system

Prerequisites

  • A basic understanding of microprocessors and microcontrollers is recommended
  • A basic understanding of digital logic or hardware / ASIC design issues would be useful but not essential
  • A basic understanding of assembler or C programming would be useful but not essential
  • A basic awareness ARM cores is useful but not essential
