Nonvolatile processors have manifested strong vitality in battery-less energy harvesting sensor nodes due to their characteristics of zero standby power, resilience to power failures and fast read/write operations. However, I/O and sensing operations cannot store their system states after power off, hence they are sensitive to power failures and high power switching overhead is induced during power...
Energy harvesting has been widely investigated as a promising alternative for future wearable sensors or internet-of-things. However, power and performance overhead is induced when IO operations are interrupted by power failures because non-preemptive characteristic of IO operations causes expensive re-executions. Furthermore, the state-of-art IO devices need long and power hungry initializing process,...
Nonvolatile processors offer a number of desirable properties including instant on/off, zero standby power and resilience to power failures. This paper presents a fabricated nonvolatile processor based on ferroelectric flip-flops. These flipflops are used in a distributed fashion and are able to maintain system states without any power supply indefinitely. An efficient controller is employed to achieve...
Nonvolatile processor has become an emerging topic in recent years due to its zero standby power, resilience to power failures and instant on feature. This paper first demonstrated a fabricated nonvolatile 8051-compatible processor design, which indicates the ferroelectric nonvolatile version leads to over 90% area overhead compared with the volatile design. Therefore, we proposed a compare and compress...
