Review of Arylic H50 wireless stereo amplifier with TIDAL Music

We’ve recently completed the review of the Arylic BP50 Bluetooth preamplifier where we tested the audio quality while streaming audio from the TIDAL Music app. But RAKOIT also sent us the Arylic H50 wireless stereo amplifier for review, and we’ll report on our experience with that device today using the TIDAL Music app again. The H50 is an audio streaming player with a digital-to-analog (DAC) converter chip and a built-in power amplifier. It supports wireless networks such as WiFi and Bluetooth and plenty of wired connections namely analog RCA line In, analog RCA phono In, digital optical in, Subwoofer out, RJ45 LAN port, HDMI ARC, USB Type-A Host, and USB Type-C. To use the Arylic H50, simply connect the output signal cable to stereo speakers (passive speaker) with 50 watts of output power on each side, allowing you to stream music from various services through the 4STREAM app or Spotify, […]

microSD Express memory cards to support up to 2GB/s data transfers

SD Association (SDA) has announced the new SD 9.1 specification that doubles the speed of microSD Express memory card speed up to 2GB/s, defines four new SD Express Speed Classes to ensure guaranteed minimum sequential performance levels, and adds support for multi-stream access and related power and thermal management to assure the guaranteed performance. We first covered the microSD Express cards in 2019 as they were added to the SD 7.0 specification with promises of SSD performance through a PCIe 3.0 interface delivering up to 985MB/s. Over four years have passed since then, and I have yet to write about devices supporting the new standard, but the SD Association is not giving up with the introduction of the SD 9.1 specification that doubles the speed of the microSD Express cards, and full-size SD Express card can even reach close to 4GB/s. More specifically, the maximum speed achievable on microSD Express […]

Generative AI on NVIDIA Jetson Orin, Jetpack 6 SDK to support multiple OSes

NVIDIA has had several announcements at ROSCon 2023 related to robotics & embedded with highlights including generative AI on the NVIDIA Jetson Orin module and the Jetpack 6 SDK will be released next month (November 2023) with supports for Ubuntu as usual, but also other operating systems and platforms such as Debian, Yocto, Wind River, Redhawk RTOS, and Balena. Generative AI on NVIDIA Jetson Orin There’s been a lot of hype in the last year about generative AI thanks to services such as ChatGPT, Google Bard, or Microsoft Bing Chat. But those rely on closed-source software that runs on powerful servers in the cloud. As we noted in our article about the “AI in a box” offline LLM solution there are some open-source projects such as Whisper speech-to-text model and Llama2 language models that could be run on embedded hardware at the edge, but as noted by some readers platforms […]

SiFive announces Intelligence X390 NPU, Performance P870 RISC-V core

SiFive has announced two new high-performance IP blocks with the Intelligence X390 NPU and the Performance P870 RISC-V core that should find their way into SoC designed for Generative AI and ML applications. We had already covered the Performance P870 and its automotive sibling – the P870-A – from information in an earlier presentation, but the SiFive Intelligence X390 NPU is new to me and appears to be aimed at generative AI in data centers, although we will very soon be seeing companies implement generative AI at the edge in pretty powerful embedded devices. SiFive Performance P870 highlights: Full support for the RVA23 RISC-V profile specification and Vector 1.0 and Vector Crypto Six-wide, out-of-order 64-bit core Up to a 32-core cluster >12 SpecINT2k6/GHz, or a 50% peak single thread performance upgrade over the previous generation SiFive Performance P670 SiFive Features 2x 128b VLEN RVV Vector crypto and hypervisor extensions IOMMU […]
