As the rate at which digital data is generated continues to grow, so does the need to ensure that data can be stored securely. The use of an NSA-certified Inline Media Encryptor (IME) is often required to protect classified data, as its security properties can be fully analyzed and certified with minimal coupling to the environment in which it is embedded. However, these devices are historically purpose-built...
Non-volatile storage is an important element for many low-power wearable sensor platforms for data aggregation, audit logs, and to enable offline analytics and debugging. NAND flash is an increasingly appealing choice due to its low cost, low power consumption, and small footprint; but it requires high software complexity and overhead to use effectively in such resource-constrained environments. Many...
The synchronization of accesses to shared memory buffers in multi-core platforms can be realized through lock-based synchronization protocols. If the embedded application executing on the system has hard real-time constraints, the worst-case blocking times for accessing remotely shared resources can negatively impact the schedulability guarantee. In this case, wait-free communication protocols can...
This paper presents the effort taken in re-designing the microprocessor systems course to ECE students. After managing to introduce wireless and multi-sensory systems in previous years, students' approaches to deal with system complexity brought about new challenges. In this paper, the new relevant topics introduced in the current course offering are described. Course organization is outlined, together...
Multi-sensor data fusion is an efficient method to provide both accurate and fault-tolerant sensor readouts. Furthermore, detection of faults in a reasonably short amount of time is crucial for applications dealing with high risks. In order to deliver high accuracies for the sensor measurements, it is required to perform a calibration for each sensor. This paper focuses on designing a fault-tolerant...
