Embedded Systems Software Development


 register

Course Description
This two-day course introduces you to software design and development for Xilinx embedded processor systems. You will learn the basic tool use and concepts required for the software phase of the design cycle, after the hardware design is completed.

Topics are comprehensive, covering the design and implementation of the software platform for resource access and management. Major topics include device driver development and user application debugging and integration. Practical implementation tips and best practices are also provided throughout to enable you to make good design decisions and keep your design cycles to a minimum. You will have enough practical information to get started developing the software platform for a Xilinx embedded system based on a PowerPC® 440 or MicroBlaze™ processor.

While this course includes many of the topics presented in the Embedded Systems Development and Advanced Features and Techniques of Embedded Systems Development courses, the focus is on software development concepts and practices rather than hardware development. Hardware design concepts and procedures are not covered.

Duration
2 days

Who Should Attend
Software and hardware design engineers interested in system design and implementation, platform software support, and software application development and debugging. This course is not for the hardware-only embedded designer.

Prerequisites

  • C or C++ programming experience, including general debugging techniques
  • Conceptual understanding of embedded processing systems including device drivers, interrupt routines writing / modifying scripts, user applications, and boot loader operation

Why this training pays huge dividends
After completing this comprehensive training, you will be able to:

  • Implement an effective software design for a Xilinx embedded system using the Xilinx tools
  • Write a basic user application using the Xilinx Software Development Kit (SDK) and run it on the embedded system.
  • Use Xilinx debugger tools to troubleshoot user applications
  • Apply software techniques to improve operability
  • Reduce embedded software development time

Lab Descriptions

  • Lab 1: Basic System Implementation – Construct the hardware and software platforms used for the labs in this course. Begin with Base System Builder to create the hardware design. Specify a basic software platform and add a software application to the system.
  • Lab 2: Application Development – Create a simple software application project from provided source files for a software loop-based stopwatch. Research hardware and software documentation to complete the application; then download it to hardware.
  • Lab 3: Software Interrupts – Replace a software timing loop with an interrupt-driven timer. Add the timer software and write an interrupt handler for the timer. Configure the FPGA, download, and test the application.
  • Lab 4: Debugging – Set up the SDK debug perspective and the previous lab’s stopwatch application for debugging, setting breakpoints, calculating interrupt latency, and stepping through the program’s operation.
  • Lab 5: SDK Profiling – Profile a program, interpret profile reports, then enable cache and rewrite code to archive optimal performance.
  • Lab 6: Writing a Device Driver – Create the skeleton driver framework, add an LCD device driver, create the BSP, and verify proper device driver operation via a download to hardware test.
  • Lab 7: File Systems – Implement a standalone software platform that incorporates the XilMFS memory file system. Develop an application that performs file-related tasks on external memory.
