Fast Boot and Start Up Sequenzes with OS-9

Achieve Fastest System Startup Sequences

  • Reflection on general optimization aspects on design and system level
  • Comparison of General Purpose Operating Systems to Real Time OSes with special focus on OS-9, on a Freescale i.MX53 ARM Cortex-A8 platform
  • Effects of different boot media on timing results

Instant on experiences and requirements are often fundamental design criteria for embedded system applications. The timing from hard reset to full operation is mainly affected by the selected operating system, its characteristics and deployed boot media. The paper provides an introduction in general design aspects to achieve fast start up timings, especially caused by different operating systems like a general purpose OS or RTOS. Additionally an overview is given on boot media and its effects on the startup behavior. Comparisons of Linux, WinCE to the RTOS Microware OS-9 and achieved timing results on an i.MX53 system are presented additionally.
