Abstract
This work presents the first energy-efficient, real-time image reconstruction processor for IoT compressive sensing. The chip implemented in 40 nm CMOS dissipates only 26.4 mW with a throughput of 60 fps for VGA images, delivering 5.4 × 106 × and 6.5 × 104 × higher energy and area efficiency than a high-end CPU. It supports an equivalent throughput of 18.6 MS/s for 2 D images, achieving 27.2 × and 19.5 × improvements in energy and area efficiency than state-of-the-art 1D compressive sensing reconstruction processors.
