While it is possible to write highly optimised code for this platform it is timeconsuming for users looking to quickly prototype a sensing application. These training materials are an introduction to rtos basics as well as a look at more advanced rtos features.
As you will see throughout the book, however, these techniques are general in scope and have uses in numerous other branches of digital image processing. To do this, developers typically add a second processing platform one for windows, the other for the rtos. Real time operating system real time operating systems are used as os in real time system. I realized that the same material with some extension can be useful to most embedded engineers who are beginners in learning about rtos. Rtos resources and tutorials we are proud to present a range of realtime operating system rtos training materials for you to build and refresh your real time os skills. Often a more efficient solution for image processing tasks is to use an fpga rather than a microprocessor since it allows massive parallelisation and pipelining, and implements algorithms directly in logic hardware rather than sequential software instructions so that very sophisticated image processing can be achieved at relatively low clock. I came across many embedded engineers who are not comfortable to use realtime. Sampling resolution image processing attempts to extract information from the outside world through its visual appearance.
