The application is divided into the following functional blocks:
• GUI
• Control and decision making
• User space device control
• Software Sobel filter processing
The first three components run in one thread of the application, while the software Sobel
filter runs in a second separate thread. The Linux kernel is in SMP mode and both the cores
are utilized for running different threads. At run time, the kernel assigns one of the cores for
software Sobel filter processing and other core for running the rest of the application and
the operating system.
