The C programmer's guide to Verilog by Lara Simsic Now that hardware is designed in high-level languages, the fields of hardware and software development are beginning to merge. Here's an introduction to hardware design in Verilog for the uninitiated.
Encrypting data with the Blowfish algorithm by Bill Gatliff Many embedded systems depend on obscurity to achieve security. We often design systems to download unsigned or unencrypted firmware upgrades or store unencrypted user data, a practice we justify because it's invisible to the end user and makes our lives easier. The stealthy practice, however, is no longer kosher. With the help of this public-domain encryption algorithm, we can clean up our act.
Where testing fails by Sean Beatty Testing, alone, cannot find all potential failure points for real-time embedded software, particularly in multithreading environments. Here are several techniques you can use to find errors that may otherwise be missed.
Where testing fails, part 2 by Sean Beatty Testing, alone, cannot find all potential failure points for real-time embedded software, particularly in multithreading environments. In part 2 of Sean Beatty's article on errors that escape detection, the focus is timing and reentrancy problems.
