This paper proposes Recryptor, an energy efficient and compact ARM Cortex-M0 based reconfigurable cryptographic processor using in-memory computing. Recryptor is capable of accelerating a wide range of cryptography algorithms and standards, including public/private key cryptography and hash functions, by augmenting the memory of a commercial general purpose IoT processor resulting in a highly compact...
Deep learning has proven to be a powerful tool for a wide range of applications, such as speech recognition and object detection, among others. Recently there has been increased interest in deep learning for mobile IoT [1] to enable intelligence at the edge and shield the cloud from a deluge of data by only forwarding meaningful events. This hierarchical intelligence thereby enhances radio bandwidth...
Precise depth estimation is a key kernel function to realizing autonomous navigation on micro-aerial vehicles (MAVs). The state-of-the-art semi-global matching (SGM) algorithm has become favored for its high accuracy. In particular, it effectively handles low texture regions due to its global optimization of the disparity between a left and right image over the entire frame. However, SGM involves...
This paper presents a face recognition accelerator for HD (1280×720) images. The proposed design detects faces from the input image using cascaded classifiers. A SVM (Support Vector Machine) performs face recognition based on features extracted by PCA (Principal Component Analysis). Algorithm optimizations including a hybrid search scheme that reduces the workload for face detection by 12×. A new...
