Technologies and Techniques to Accelerate Embedded Development

I’ve recently attended a webinar entitled “Accelerate Your Next Embedded Development Project: Essential Tools and Techniques for Every Phase of Your Project Lifecycle” presented by Wind river and VDC Research. The two speakers were: Marc Brown, Wind River VP, Tools and Marketing Operation. Christopher Rommel, Senior Analyst at VDC Research. The webinar was composed of three sections: Industry Challenges. (Wind River) Embedded Development: Data and Trends. (VDC Research) New ways to accelerate development (Wind River) Industry challenges Marc describes the new challenges for device software drivers: Increased security, safety and quality requirements for connectivity Performance scalability: multi-cores, many cores and SoC support. Pressure to lower OPEX (Operating Expenses) Companies are now pushed to increase performance, become more cost effective and provide a better connectivity while at the same time decrease time to market, project risks and security issues. Data and Trends Christopher first present a slide showing there are still […]

Best Practices for Writing Safer C Code

Thomas Honold wrote an article published on EETimes giving 17 steps to safer C code. Not only this article provides tips to write safer C code, but I believe those steps are simply best practices when writing C code for embedded systems as they shorten the software life cycle by making it easier for a software team to write, debug and maintain code and by improving the software QA procedure. Here’s a summary of the 17 steps to achieve safer C code: Follow the rules you’ve read a hundred times: Initialize variables before use. Do not ignore compiler warnings. Check return values. Use enums as error types. Define an ENUM_MAX value at the end, so that the code to check the range does not have to be modified each time you add a new error code. Expect to fail Always assume there will be an error and set to default […]

Embedded Linux QA with Wind River Test Management 4.0

Wind River has just announced the release of Winder River Test Management 4.0, a test suite specialized in testing embedded devices and allowing the test teams to optimize the testing effort by focusing resources on high-risk areas and deliver a high-quality embedded software solution on time. New Features and Enhancements New preconfigured test suite generators: The following new test suite generation methods are available: Create a test suite based on coverage and execution time: Selects test case instances that will generate the maximum coverage given a fixed time constraint . Create a test suite based on execution results: Selects test case instances that have run with specific final status values. Create a test suite based on requirements: Selects test case instances that are associated with specific requirement records to ensure that all requirements have a test associated with them and are thoroughly tested. Create a test suite based on defect […]
