Securing Smart Connected Homes with OTP NVM

The market for piracy is huge and hackers have become increasingly sophisticated even when security is implemented in hardware. The race between the aggressors and protectors is a battle without end. Smart connected home devices are increasingly storing and processing very sensitive and private user data in addition to attempting to deliver copyright protected content from service providers. Protecting consumer data is vital.

Why the Memory Subsystem is Critical in Inferencing Chips

The number of new inferencing chip companies announced this past year is enough to make your head spin. With so many chips and no lack of any quality benchmarks, the industry often forgets one extremely critical piece: the memory subsystem. The truth is, you can’t have a good inference chip unless you have a good memory subsystem.

Pyramid Vector Quantization and Bit Level Sparsity in Weights for Efficient Neural Networks Inference

This paper discusses three basic blocks for the inference of convolutional neural networks (CNNs). Pyramid Vector Quantization (PVQ) is discussed as an effective quantizer for CNNs weights resulting in highly sparse and compressible networks. Properties of PVQ are exploited for the elimination of multipliers during inference while maintaining high performance. The result is then extended to any other quantized weights. The Tiny Yolo v3 CNN is used to compare such basic blocks.

Enabling Bluetooth Out-of-Band pairing through NFC

Many services offered over Bluetooth can expose private data or let a connecting party control the Bluetooth device. Security reasons make it necessary to recognize specific devices, and thus enable control over which devices can connect to a given Bluetooth device.
