Dual-core audio MCU has hardware acceleration for FFT and neural networks

Knowles has announced a dual-core audio processor chip for multi-microphone edge processing  – for example, for local spoken-word control of products. Called IA8201, it includes a 128bit four-way floating-point SIMD ‘DeltaMax’ core for beam-forming, barge-in, acoustic echo cancellation (AEC) and machine learning, for example, and a Tensilica HiFi3 core ‘HemiDelta’ with two-way floating-point SIMD for ...

UK fusion machine uses 2.5MJ capacitor bank

UK company First Light Fusion (FLF) aims to achieve controlled nuclear fusion by 2024 using a method that involves firing projectiles into a target at very high speed – currently almost 20km/s in its ‘Machine 3’, from an electromagnetic accelerator. Power for projectile acceleration comes six banks of capacitors arranged radially around a central vacuum ...

IMS: GaN-on-SiC HEMT beats (most) magnetrons for efficiency

NXP claimed to have a transistor that “exceeds the efficiency of most magnetrons at 2.45GHz” at the International Microwave Symposium in Boston US. “For more than 50 years, 2.45GHz magnetrons have been widely used in consumer and industrial applications ranging from microwave ovens to high power welding machines,” said the firm. “Solid-state solutions appeared on ...

Rohde & Schwarz bundle pricing for scopes and more

Rohde & Schwarz has some special offers on its entry-level scopes, spectrum analysers, power supplies and power analysers. The idea is that the deals, which last until the end of the year, include a lot of optional extras, which the customer pays for early at a reduced price rather than waiting to buy them later ...

Tek gives mid-range scopes high-end displays

Tektronix has revamped its oscilloscope mid-range with two new products: 3 Series and 4 Series, both getting their user-interface from the existing high-end 5 and 6 Series, from which the 4 Series MSO (mixed-signal oscilloscope) also gets its Tek049 front-end ADC/asic hardware, while the 3 Series MDO (mixed-domain oscilloscope) gets the earlier Tek26 front-end. “The oscilloscopes have ...

Cadence machine can prototype a 1bn gate SoC on FPGAs

For software development without final silicon, Cadence has launched FPGA-based hardware that can simulate SoCs with up to a billion gates. Called Protium X1, it is intended for debugging software intended to run on SoCs that have yet to be fabbed – for AI, 5G mobile and graphics processors, for example. It can run a 1bn ...

AI helps drones land quickly and smoothly despite turbulence

Artificial intelligence can help compensate for turbulence as a drone lands, according to the California Institute of Technology. “Complex turbulence is created by the airflow from each rotor bouncing off the ground as the ground grows ever closer during a descent,” according to Caltech. “This turbulence is not well understood nor is it easy to ...
