RTOS White Papers

We added the following RTOs white papers to Embedded Star:

• Linux Can Be Used in the Military
  Sweeping generalizations have certainly fueled the fear, uncertainty and doubt (FUD) surrounding the use of Linux in the military.
• How to Use Real-Time Multitasking Kernels In Embedded Systems
  Not all real-time systems gain from using a real-time kernel.
• Symbian Signed
  This white paper outlines the scope and context of Symbian Signed, an industry-wide application signing and verification process for Symbian OS third party applications.
• Symbian Smartphones for the Enterprise
  The growth of wireless computing belongs to the smartphone, a powerful device that extends the superb voice functionality of a mobile phone into the realm of data communications.
• What is Real Time and Why Do I Need It?
  Real time is an often misunderstood property of operating systems. This article attempt to provide a summary of some of the critical elements of realtime computing and discuss a few design considerations and benefits.
• Talking to hardware under QNX Neutrino
  In this article, we'll focus on the low-level details of accessing and controlling device-level hardware, which are common to all types of device drivers.
• RTOS Real-Time Performance vs. Ease Of Use
  Given that real-time performance is often cited by developers as paramount in their list of criteria for selection of an RTOS, it's easy to see why OS vendors respond to this demand for performance with measurements designed to show that their RTOS is faster than the competition, and therefore better.
• Efficient Embedded Memory Protection for Express Logic's ThreadX Real-Time Operating System (RTOS)
  This paper describes an approach that is designed to provide memory protection for embedded systems. Embedded Memory Protection (EMP) provides the benefits of memory protection without the typical overhead or complexity of desktop approaches.
• ThreadX Performance Analysis
  The focus of this document is on ThreadX performance analysis. Such analysis is necessary in order to debug application deadline problems. It is also very useful in pre-production system tuning and verification.
• RTOS Interrupt Architectures: Two Approaches - Unified and Segmented
  Like stand-alone systems, embedded applications running on top of real-time operating systems (RTOSes) require Interrupt Service Routines (ISRs) to handle interrupts generated by external events.
