Ohm’s Law is the classical physics explanation of the linear relationship between voltage, current, and resistance in a conductor. Quantum mechanics provides insights into the mechanisms behind this behavior, explaining why Ohm’s Law still holds true even on very small scales where quantum effects are significant. Ohm’s law is a macroscopic view of classical physical […]
FAQ
What does a watchdog timer watch?
Watchdog timers (WDTs) watch MCU operations to ensure reliability, especially in embedded systems, robotics, medical devices, electric grid monitoring, deep space missions, and other critical applications. They are used to detect and correct MCU and software glitches without human intervention. The WDT monitors system operation by listening to signals from the MCU. The system software […]
What is the Coherent Hub Interface?
The Coherent Hub Interface (CHI) is used in system-on-chip (SoC) designs to track which processor has the most recent copy of a data block, preventing other processors from using old data. CHI is used in a wide range of applications requiring high-performance cache coherence, such as mobile devices, networking equipment, automotive systems, and data centers. […]
Securing IoT devices against quantum computing risks
The key to modern asymmetric cryptography is to create an equation that is easy to solve in one direction but difficult to reverse by an adversary in the other direction. Traditionally, this was done through modular arithmetic, where a large prime modulus and a generator were used to generate a key, although there are multiple […]
