Latest Patents

Najafi's latest patents include a "Context-aware bit-stream generator for deterministic stochastic computing." This invention discloses three context-aware architectures designed to accelerate state-of-the-art deterministic methods of stochastic computing. The proposed designs utilize a control unit to extract the minimum bit-width necessary to accurately represent each input data. By reducing the lengths of bit-streams to the minimum required, the designs maintain noise-tolerance, ensuring that each bit-flip introduces only a least significant bit error. This advancement significantly improves processing time while maintaining reasonable hardware cost overhead, making deterministic bit-stream processing more appealing for applications requiring high accuracy and error tolerance.

Another notable patent is the "Method for pulse-based convolution for near-sensor processing." This invention presents a low-cost, high-performance, and energy-efficient near-sensor convolution engine based on pulsed unary processing. The design eliminates the need for expensive analog-to-digital converters, resulting in significant improvements in hardware cost and energy consumption compared to conventional fixed-point binary and stochastic computing-based designs.
