Evaluation of a low-power reconfigurable DSP architecture
TL;DR: This paper proposes an architecture that relies on dynamic reconfiguration of hardware resources to implement low-power and programmable processors for DSP applications and compares it to other programmable architectures.
Patent
Power supply control device, semiconductor device and method of driving semiconductor device
TL;DR: In this paper, a delay detection circuit was proposed to detect the delay of the delay signal (outO0') with respect to the reference signal (Oi), and a supply voltage control circuit for controlling the supply voltage (VDD) supplied to the semiconductor circuit and the monitor circuit based on the result of detection.
Proceedings ArticleDOI
Heterogeneous reconfigurable systems
TL;DR: This paper presents an overview of opportunities of reconfigurable architectures in the architecture domain, combining high-level prediction and analysis tools with partitioning, optimization and mapping techniques.
