Skyworks’ advanced AI noise suppression enables highest audio quality for new audio/video applications on the Edge

Mon, Jan 08, 2024

Skyworks Solutions is introducing its newest software solution for removing unwanted background noise from speech signals at CES 2024. The AI Noise Suppression solution delivers a new benchmark of performance for noise reduction, increasing speech intelligibility, preserving quality and reducing listener fatigue when using handsets, headsets, conference systems, automotive telematics, wireless microphones and audio-visual systems.

According to Astute Analytica, the edge AI market is predicted to grow from $1.4 million in 2021 to $8 million in 2027, with a large portion coming from the Internet of Things (IoT), wearable consumer devices and the need for faster computing in 5G networks.

While AI noise suppression has become common in desktop and cloud applications, performance lags on the edge. To address this challenge, the new software from Skyworks is highly scalable, from desktop CPU/GPU down to edge platform, with performance that rivals much larger CPU solutions.

“With the proliferation of AI noise suppression in desktop and cloud applications, it’s imperative the industry also overcomes performance lags on the edge to meet market demands,” said Yusuf Jamal, senior vice president and general manager of the Diversified Analog Solutions at Skyworks. “Skyworks is actively developing audio and other signal processing applications at the edge that will replace traditional signal processing techniques and drive new IoT edge applications. The AI Noise Suppression solution delivers benchmark performance, scalable from the edge to the cloud while requiring less memory and computational resources.”

The Skyworks AI Noise Suppression solution meets the needs of the market by:
Achieving subjective and objective test scores in embedded implementations that compete with desktop CPU/GPU solutions while requiring less than 10% CPU load on a HiFi4 core running at 600 MHz
The ability to run at 48 kHz, enabling advanced noise reduction on full bandwidth signals in audio/video production and playback
Not requiring connection to large cloud servers or tethering to desktop PCs or mobile phones
Not interfering with the original speech signal as confirmed by subjective testing based on ITU-T P.808
The solution allows for advanced noise reduction on full bandwidth signals, giving it the best audio quality on the market and opening additional applications in the areas of audio/video production and playback.

Ceva extends its Connect IP Portfolio with Wi-Fi 7 platform for high-end consumer and industrial IoT

Thu, Jan 04, 2024

Ceva has announced the general release of its next generation RivieraWaves Wi-Fi 7 IP platform, further expanding its widely-licensed portfolio of connectivity IP, targeting high-end consumer and industrial applications including gateways, TVs, set-top-boxes, streaming media devices, AR/VR headsets, personal computing and smartphones. The RivieraWaves Wi-Fi 7 IP leverages all the latest advanced features of the IEEE 802.11be standard to deliver a premium high performance, cost- and power-optimised Wi-Fi solution for integration into the next wave of Wi-Fi Access Point (AP) and Station (STA) products.

According to global technology intelligence firm ABI Research, annual Wi-Fi enabled chipset shipments will exceed 5.1 billion by 2028, with more than 1.7 billion of these chipsets supporting the Wi-Fi 7 standard. As Wi-Fi enabled device shipments continue to grow, increasing numbers of semiconductor companies and OEMs are choosing to integrate Wi-Fi connectivity into their chip designs, and need access to high quality Wi-Fi IP to reduce the development costs and risks. Spanning Wi-Fi 4/5/6 over the past decade, Ceva has already established a considerable leadership position in Wi-Fi IP licensing, with more than 40 licensees for its RivieraWaves Wi-Fi 6 IP family, serving a wide range of end markets and applications, from end points to access points, across the IoT sphere. Expanding on this leadership position, Ceva’s RivieraWaves Wi-Fi 7 IP provides a unique, comprehensive 802.11be MAC and PHY solution for integration into the next generation of Wi-Fi SoC products.

Andrew Zignani, Senior Research Director, ABI Research, commented: “Ceva’s wireless connectivity IPs play an integral role in the proliferation of connectivity standards in the broad IoT markets, as is evident from their customer’s success in shipping more than 1 billion connectivity chips annually. With the introduction of their RivieraWaves Wi-Fi 7 IP platforms, semiconductor companies and OEMs have a trusted partner to develop differentiated, high-performance Wi-Fi 7 chipsets for their connectivity roadmaps, with lower risk and a lower cost of ownership.”

Tal Shalev, Vice President and General Manager of the Wireless IoT BU at Ceva, stated: “The relentless expansion of Wi-Fi usage has pushed the Wi-Fi 7 standard to offer enhanced data throughput, improved latency and support more spectrum in the face of mounting network congestion. Achieving this requires highly complex, cutting-edge functionalities like 4K QAM modulation, Multi Link Operation and Multi Resource Unit to optimize link efficiency across the available bands. Our RivieraWaves Wi-Fi 7 IP platform incorporates all the features of this latest-generation, wireless standard, dramatically simplifying development and time-to-market for companies looking to add Wi-Fi 7 connectivity to their products.”

Wi-Fi 7’s 4K QAM modulation scheme is a substantial increase on the previous 1K QAM of Wi-Fi 6, while Multi Link Operation (MLO) introduces dynamic channel aggregation, seamlessly combining heterogenous channels from the same or different bands to navigate interference and boost throughput. Similarly, Multi Resource Units (MRU) enables the creation of larger channel bandwidths by intelligently stitching together punctured or disjointed Resource Units within the same band. The outcome is not only a remarkable up to 5 times increase in raw speeds but also significantly reduced latency, thanks to diminished contentions and retries.

Nordic-powered module provides Bluetooth LE audio connectivity

Tue, Dec 19, 2023

Wireless communications company Rayson Technology has released a multiprotocol module based on Nordic Semiconductor’s nRF5340 System-on-Chip (SoC). The SoC is designed for advanced Bluetooth LE audio applications, as well as sophisticated metering, wearable, smart home, industrial, and medical use cases. Measuring just 16.5 by 13.0 by 2.5 mm, the ‘BTM-N340X’ module supports LE Audio and its Low Complexity Communication Codec (LC3), which together enable higher quality, lower power wireless audio streaming compared with existing Classic Bluetooth audio solutions.

The module employs the nRF5340 SoC’s dual Arm Cortex-M33 processors – providing a high performance application processor capable of DSP and Floating Point (FP) alongside a fully programmable, ultra low power network processor. The application core manages the LC3 codec, while the Bluetooth LE protocol is supervised by the network processor.

“The BTM-N340X module has been designed for a wide range of applications, aiming in particular to provide enhanced audio experiences via Bluetooth LE Audio,” says Bob Wu, CTO at Rayson Technology. “It enables one device to stream audio to multiple pairs of wireless headphones, and can facilitate audio broadcasts through public address systems, such as in airports and museums. This module is also compatible with smart speakers and home audio systems.”

The module’s ultra-low power consumption is made possible due to the nRF5340’s power-optimised multiprotocol radio, which offers a TX current of 3.4 mA (0 dBm TX power, 3 V, DC/DC) and RX current of 2.7 mA (3 V, DC/DC). The sleep current is as low as 0.9 µA. Additionally, because the cores can operate independently, developers have the flexibility to optimise performance for power consumption, throughput, and low latency response.

Two flexible antenna options are available for the module—a pre-certified U.F.L Connector and a PCB pin out—depending on the product application. The module is designed to operate within a temperature range of -40 to +85°C.

“The dual processors made the nRF5340 SoC an excellent choice for this module’s LE Audio applications,” says Wu. “The large memory capacity, radio sensitivity, and low power consumption were also major drawcards. In addition to the excellent technical capabilities of the chip, the high level of support from Nordic was a key factor when making our selection.”
