Software-based neural video decoder leverages AI accelerator on Snapdragon 888

Sometimes hardware blocks got to work on tasks they were not initially designed to handle. For example, AI inference used to be mostly offloaded to the GPU before neural network accelerators became more common in SoC’s. Qualcomm AI Research has now showcased a software-based neural video decoder that leverages both the CPU and AI engine in Snapdragon 888 processor to decode a 1280×704 HD video at over 30 fps without any help from the video decoding unit. The neural video decoder is still a work in progress as it only supports intra frame decoding, and inter frame decoding is being worked on. That means each frame is currently decoded independently without taking into account small changes between frames as all other video codecs do. The CPU handles parallel entropy decoding while the decoder network is accelerated on the 6th generation Qualcomm AI Engine found in Snapdragon 888 mobile platform. This […]

$3.5 RV-Debugger Plus UART & JTAG debug board comes with BL702 Zigbee & BLE RISC-V SoC

USB to UART debug boards are a necessity for anyone playing with single board computers, at least when using bleeding-edge bootloader or Linux kernel where the target board may not always boot, or when troubleshooting booting problems. Those are often based on FDTI or WCH chips, but Sipeed RV-Debugger Plus features Bouffalo Lab BL702 Zigbee & Bluetooth LE RISC-V SoC instead and offers both UART and JTAG interfaces. So let’s have a look at both the board and SoC. Sipeed RV-Debugger Plus USB to TLL debug boards are meant to be simple and that’s the case for Sipeed latest BL702 board as it comes with a 12-pin connector with Tx/Rx for UART, 8 signals for JTAG, plus 5V, 3.3V, and GND power signals. We can also see pads for Tx/Rx/CTS, a boot button, a crystal oscillator, and a USB-C port to connect to the host computer. What I don’t see […]

10BASE-T1L Ethernet chips enable up to 1.7 kilometer long Ethernet cables

The maximum length of Ethernet cables used to be 100 meters. While that may be more than enough for most applications, it does not cut it for industrial communication applications. So the 10BASE-T1L Ethernet physical layer standard (IEEE 802.3cg-2019) was approved by the IEEE on November 7, 2019 to allow for cables over one kilometer using a single twisted-pair cable. Analog Devices has launched two 10BASE-T1L Ethernet chips with ADIN1100 Ethernet PHY and ADIN1110 Ethernet MAC-PHY that allow for up to 1.7 kilometer long Ethernet cables. Let’s check out ADIN1100 specifications for reference: 10BASE-T1L IEEE Std 802.3cg-2019 compliant Cable Reach 1700 meters+ with 1.0 V pk-pk 1700 meters+ with 2.4 V pk-pk Auto-Negotiation capability Supports intrinsic safety applications MII, RMII & RGMII MAC interfaces MDIO Management Interface Unmanaged configuration using pin strapping including: Master/Slave selection Transmit amplitude PHY address 25 MHz crystal oscillator/25 MHz external clock input (50 MHz external […]

RasPad 3 Review – Part 2: A Raspberry Pi 4 mini PC with integrated display

I started RasPad 3 review last week with an unboxing of the tablet shell for Raspberry Pi 4, together with assembly instructions, and a first boot after flashing Raspad OS to the system. In the first part of the review, I mentioned that I’d probably focus the remainder of the review on Ezblock Studio visual programming IDE, as the rest of the software is almost the same as using a standard Raspberry Pi 4, the other difference being the touchscreen-friendly RasPad launcher. But Sunfounder explained to me it would be hard to check out Ezblock as it’s designed to control robots and other hardware platforms, and requires an extra HAT (see Kickstarter campaign) to allow the Ezblock APP to connect through Bluetooth (it cannot be directly linked to Raspberry Pi through the built-in Bluetooth). Here’s an example of a robot that is compatible with Ezblock Studio: Picar-X. Finally, I was […]
