Amazing stuff!
"... researchers have developed a low-power microchip they call a "microwave brain," the first processor to compute on both ultrafast data signals and wireless communication signals by harnessing the physics of microwaves. ..."
the processor is the first true microwave neural network and is fully integrated on a silicon microchip. It performs real-time frequency domain computation for tasks like radio signal decoding, radar target tracking and digital data processing, all while consuming less than 200 milliwatts of power. ..."
From the abstract:
"The development of high-bandwidth applications, including multi-gigabit communication and radar imaging, demands faster processing. However, in the microwave regime, where frequencies exceed clock rates, sampling and computation become challenging.
Here we report an integrated microwave neural network for broadband computation and communication. Our microwave neural network operates across tens of gigahertz but is reprogrammed with slow megabits per second control bitstreams.
By exploiting strong nonlinearity in coupled microwave oscillations, it expresses its computation in a narrower spectrum, enabling easy read-out. The system searches bit sequences in multi-gigabits per second data and emulates digital functions without custom circuits. It accelerates radio-frequency machine learning by classifying encoding schemes and detecting frequency shifts to track flight trajectories from radar.
The microwave neural network is fabricated with standard complementary metal–oxide–semiconductor technology. It occupies a sub-wavelength footprint of 0.088 mm2 on chip and has a sub-200-mW power consumption, supporting integration in a general-purpose analogue processor."
