To save resources for Internet of Things (IoT) devices, a proposed approach segments operands and corresponding basic arithmetic operations that can be carried out by approximate function units for almost all applications. The approach also increases the security of IoT devices by hiding information for IP watermarking, digital fingerprinting, and lightweight encryption.
Due to the increasing chip temperature and the strong dependency of leakage power on temperature, thermal aware power management has received a considerable amount of attention recently in energy efficient system design. In this paper, we propose a temperature-aware intra-task scheduling algorithm to minimize leakage energy in real-time systems. The basic idea of our algorithm is to run tasks at full...
Peak current is one of the important considerations for circuit design and testing in the deep sub-micron technology. In a synchronous finite state machine (FSM), it is observed that the peak current happens at the moment of state transitions and it has a strong correlation with the maximum number of state registers switching in the same direction simultaneously [2], which we refer to as the peak...
Recently, a transistor level dual-Vth technique has been proposed, where transistors within the same cell are allowed to have different Vth to form the so-call mixed Vth (MVT) cell. However, it is impractical to build a full MVT cell library and include it in the standard dual Vth design flow. To make this practical, current approach adds another design phase after technology mapping to replace high...
