Stuttgart advances 6G IC research with the help of Keysight equipment
Keysight Technologies’s 6G Vector Component Analysis (VCA) instruments are being used in the development of a new 6G IC at the University of Stuttgart. This is the latest collaboration between
the two partners, with previous research being conducted on a versatile multiplexing platform for synchronous time- and frequency-domain analyses of ultra- broadband communication channels, called Crosslink. The Keysight VCA supports Crosslink by integrating sub-terahertz vector network analysis with wideband modulation capabilities. This capability enables unprecedented RF component characterisation under full complex modulated conditions. The result is best- in-class noise and linearity performance for analysis of wideband, high-frequency modulated performance of components, circuits and transceivers. VCAs help develop next-generation
amplifiers, filters, antenna systems, components, and the channel modelling required in 6G. “In collaboration with Keysight, we’re
creating an innovative measurement platform that covers a large variety of measurement configurations, and lets us evaluate the suitability of ultra- wideband channels for wireless THz communications,” said Ingmar Kallfass, a professor at University of Stuttgart. The Keysight VCA measurement
solution used for Crosslink integrates an N5245B PNA-X microwave network analyser, an M8199A arbitrary waveform generator, broadband modulation distortion vector network analyser application software, and vector signal analysis software with Virginia Diodes frequency extenders up to 330GHz. The Keysight and University of Stuttgart collaboration supports a large-scale
equipment initiative funded by the German Research Foundation. The initiative aims to prepare for a future of massive data rate increases, new types of electro-optical fibre and wireless communication systems, and the use of sub-THz RF bands. It supports the industry’s vision of introducing sustainable, agile, low-latency and high-speed 6G wireless communication networks through the development of energy-efficient, next-generation ICs.
Blueshift Memory announces AI accelerator chip
Blueshift Memory, a Cambridge (UK) based designer of a novel, proprietary high-speed memory architecture, has successfully completed a 13-month R&D project to demonstrate the performance of its Cambridge Architecture, which was funded by an Innovate UK Smart grant. The Cambridge Architecture was
developed to address the Von Neumann bottleneck – the phenomenon which shows that data transfer between the processor core and memory has become the limiting factor in computational speed. As computing tasks grow more data-hungry, the new architecture makes them more efficient, and at the same time power-efficient by eliminating unnecessary movement of data. “The Cambridge Architecture is capable
of very high levels of acceleration, up to 1000x or more, and this is the first step toward reaching computionally-demanding and data-intensive applications like servers in high-frequency trading. This high performance will also be accompanied by
dramatic energy savings, since moving large amounts of data around traditonally consumes excessive amounts of energy,” said Peter Marosan, CTO and founder of Blueshift Memory.
Recog.AI, based in Budapest, Hungary,
will distribute the chips and accelerator modules, which it also plans to use in both CCTV cameras and for cloud computing.
“The chip will offer users considerable
benefits such as faster processing, lower latency and improved energy efficiency. Alternatively, by using the solution as a standalone chip we can offer enhanced real-time image and video analysis on the edge, and integrate these devices into our own computer vision platform,” said Máté Hegedűs, CEO of
Recog.AI.
