Arm unveiled a new automotive image signal processor for ADAS. The Mali-C78AE ISP is able to process data from up to four real-time or 16 virtual cameras, includes noise reduction technology and dynamic range management, and enables camera sensors to be dual-purpose by downscaling and color-translating the outputs of sensors optimized for machine vision to create images adapted to the human eye. Designed to meet ISO 26262 ASIL B functional safety requirements and prevent or detect faults in a single camera frame that may result in incorrectly processed frame data, it has over 380 fault detection circuits, continuous built in self-test, and can detect sensor and hardware faults of connected cameras. It can be combined with Cortex-A78AE and Mali-G78AE to provide a full ADAS vision pipeline. Mobileye will use the ISP in the next generation of its EyeQ technology.

Vtool and Concept Engineering collaborated to connect the companies’ tools to provide a debug solution for both design and testbench code simultaneously.

Power devices
Infineon expanded its portfolio of isolated EiceDRIVER Enhanced gate drivers with the F3 Enhanced (1ED332x) family, which implements protection to prevent destructive short-circuit events for both conventional power switches, such as IGBTs, as well as wide-bandgap devices. The single-channel isolated gate driver offers high common-mode transient immunity (CMTI) of up to 300 kV/us and typical output currents of up to 8.5 A. It targets applications such as for industrial drives, solar systems, electric vehicle charging, energy storage systems, and commercial air conditioning.

Infineon announced a new 2-channel, analog input, class D audio amplifier multichip module (MCM). MERUS MA5332MS integrates a dual-channel PWM controller, a high-voltage gate driver, and four low R DS(ON) MOSFETs. Due to its very low R DS(on) class D output stage (24.4 mΩ typical), it can deliver 2 x 100 W at 4 Ω operating heatsink-free or 2 x 200 W at 4 Ω with a small 8°C/W heatsink. It targets consumer products such as soundbars as well as professional applications.

Memory
Kioxia started sampling Universal Flash Storage (UFS) embedded flash memory devices supporting MIPI M-PHY v5.0.

Quantum computing
DARPA announced the Underexplored Systems for Utility-Scale Quantum Computing (US2QC) program with the aim of determining if an underexplored approach to quantum computing is capable of achieving utility-scale operation much faster than conventional predictions. Complementary to the agency’s quantum benchmarking program, US2QC is focused on verifying and validating system, component, and sub-system designs for a proposed fault-tolerant quantum computer. “If there’s an underexplored area of quantum computing showing promise for a faster breakthrough than we previously expected, we want to explore it immediately and thoroughly verify and validate the approach’s viability,” said Joe Altepeter, US2QC program manager in DARPA’s Defense Sciences Office. “If a company or an organization thinks they can make a truly useful, really big, fault-tolerant quantum computer, we want to have a conversation with them. We would like them to show us exactly why they’re convinced their machine is going to be revolutionary in the near future, and we want to work collaboratively with them, pay for additional experts to embed with their team, and help advance bold concepts that withstand rigorous testing.”

Super.tech released SupermarQ, an application-centric benchmarking suite for quantum computers. The suite aims to measure a machine’s performance on a range of applications that mirror real-world problems in a variety of domains such as finance, chemistry, energy, and encryption. Instead of combining different aspects of performance into a single number, it aims to show how well a device or architecture can complete a given task, such as optimization, simulation, or error correction. “Our approach illustrates the importance of matching the device architecture to the use-case,” said said Pranav Gokhale, Super.tech co-founder and CEO.
