Jean J. Labrosse, the founder of Micrium and author of the well-known µC/OS series of software and books, presents during the 2021 Embedded Online Conference. In his presentation, Jean demystifies Memory Protection Units, also known as MPUs. He talks about an RTOS without a Memory Protection Unit, an RTOS with process separation using an MPU, inter-process communications, and organizing memory in sections or segments using the IAR tools. Furthermore, a sample linker script is shown and explained to aid in further organizing memory for use with an MPU. As usual, a lengthy list of recommendations is given at the end of the presentation.
