Abstract Machine learning has become a mainstream solution applied across various industries. In this work, we investigate how to use side-channel information such as timing and electromagnetic (EM) emissions to perform reverse engineering of neural networks. To this end, we consider multilayer perceptrons and convolutional neural networks as the choices of machine learning architecture, assuming … Read more
Overview of Embedded Systems //From Hardware Perspective：“Embedded” integrates peripheral devices based on the CPU into the CPU chip itself. For example, early computers based on the X86 architecture had CPUs that only performed computation and accumulation functions. All chips needed external bridges to expand functionality, such as serial ports that relied on external 16C550/2 serial … Read more
The low-altitude economy is booming, and the EVTOL trend is rising. The flight control system is the core system of the aircraft, and it involves transition phases that are not present in general aircraft, posing greater safety challenges. Based on this, we take the development of fully autonomous control laws for vertical take-off and landing … Read more
