  • Device, system, and method of determining memory requirements and tracking memory usage
    Patent number: 11860795
    Abstract: Device, system, and method of determining memory requirements and tracking memory usage. A method includes: dynamically modifying, in an iterative process including two or more iterations, a maximum size of Random Access Memory (RAM) that a Memory Protection Unit (MPU) authorizes an executable program code to access. In each iteration, the method includes running that executable program code while the MPU enforces a different maximum size of RAM, and monitoring whether the executable program code attempted to access a RAM memory address that is beyond that maximum size of RAM in that iteration. Based on such iterations, the method determines a minimum size of RAM that is required for that executable program code to run without causing a memory access fault.
