QEMU 5.0 Supports Recent Armv8.x Features, Cortex-M7 CPU, Host Directory Access, and More

QEMU (Quick EMUlator) is an open-source emulator that’s great to run programs on various architectures such as Arm, RISC-V, and many others when you don’t own proper hardware. The developers have now released QEMU 5.0.0 will plenty of new features and such as support for Armv8.1 to Armv8.4 architectures, Arm Cortex-M7 processor, various changes to MIPS, PowerPC, RISC-V, s390… architectures, support for accessing a directory on the host filesystem from the guest using virtiofsd and more. There have been over 2800+ commits from 232 developers, so the list of changes to too long to write here, but some of the highlights include: Support for passing host filesystem directory to guest via virtiofsd Support for ARMv8.1 VHE/VMID16/PAN/PMU, ARMv8.2 UAO/DCPoP/ATS1E1/TTCNP, ARMv8.3 RCPC/CCIDX, ARMv8.4 PMU/RCPC Added ARM Cortex-M7 CPU support New Arm boards: tacoma-bmc, Netduino Plus 2, and Orange Pi PC Allwinner SoC model now wires up the USB ports TPM support for […]

BashTop is a Linux Resource Monitor for the Terminal

Neil Amstrong of BayLibre recently added ODROID-C4 support to Armbian, fired up Rosetta@Home on the Amlogic S905X3 SBC, and took a screenshot of some kind of advanced htop program showing the Rosetta@Home and other processes running. And… Rosetta@Home starting ! pic.twitter.com/w10hjwppLR — Neil Armstrong @superna9999@social.linux.pizza (@Superna9999) April 27, 2020 The program used happens to be BashTop a recently released Linux resource monitor written in Bash and running in a terminal. Installing the script and running it is super easy:

git clone https://github.com/aristocratos/bashtop
cd bashtop
./bashtop

git clone https://github.com/aristocratos/bashtop

cd bashtop

./bashtop

I tried it in an AMD Ryzen 7 laptop running Ubuntu 18.04. You’ll need at least a 80×25 terminal window, but it looks much better in full screen. It shows CPU use in graphical and text forms, memory and storage usage, a list of processes, as well as network usage both in graphical and text forms. You can also select each individual process to get more information or kill it. […]

Rockchip RK3588 8K TV Box Triples as 5G & WiFi 6 Router, Home Automation Gateway

Rockchip RK3588 octa-core Cortex-A76/A55 processor was only expected in the second half of 2020 for IoT and vision/AI applications, but at least one company is working on a 3-in-1 product based on Rockchip high-end processor with a “5G AIoT 8K TV box” that also works as a 5G and WiFi 6, and with features such as Zigbee can also act as a home automation gateway. “5G AIoT Android TV Box” preliminary specifications: Main SoC – Rockchip 3588 octa-core processor with 4x Cortex-A76 and 4x Cortex-A55 cores in dynamIQ configuration, Arm “Natt” GPU (i.e. NOT Mali-G31 MP2), NPU 2.0, 8K H.265/AV1 video decoder, 4K video encoder System Memory – 4GB DDR4 Storage – 32GB eMMC flash, MicroSD card slot up to 64GB?! Video Output – HDMI 2.1 up to 8K resolutions Audio – SPDIF audio output, HDMI audio Connectivity 802.11 b/g/n/ac/ax WiFi 6 and Bluetooth 5.1 via Qualcomm QCA6391 WiSoC 1x […]

Allwinner V831 AI Full HD Camera SoC Powers Sochip V831 Development Board

In the last year or so, we’ve started to see several camera SoCs with a built-in NPU or SIMD instructions to accelerate face detection, objects detection and so on, starting with the low-resolution Kendryte K210 processor to the 2.5K Ingenic T31 MIPS video processor, or even the 4K capable iCatch V37 camera SoC. Allwinner introduces several camera processors (V3, V316, S3…) in the past, but none of them included an NPU aka AI accelerator. This has now changed with Allwinner V831 Cortex-A7 Full HD camera SoC also including a small 200 GOPS NPU. Sochip / Allwinner V831 AI Camera SoC Specifications: CPU – Single-core Arm Cortex-A7 processor @ up to 800 MHz with NEON, 32KB L1 instruction cache and 32KB L1 Data cache, 128KB L2 cache AI Accelerator – 0.2 TOPS (200 GOPS) NPU for face recognition, face detection, and “humanoid detection network” System Memory – 64MB on-chip DDR2 RAM […]

NANOTE 7″ 2-in-1 Mini Laptop with Intel Atom X5 Processor to Launch for $185 in Japan

Mini laptops have been a thing for the last 2 or 3 years thanks to companies such as GPD and OneNote. However, most of the models rely on fairly powerful and expensive low-power processors from Comet Lake and Amber Lake families, and that may be fine if you want a versatile, ultra-portable machine as your main driver, but not everybody wants to spend $700-$1,000 on this type of device. In the recent past, we’ve seen a couple of cheaper Intel Cherry Trail mini laptops such as Pretech F700mi and Peakago. But the former does not appear to be for sale, and the latter was offered for $269 and the company decided to upgrade it to an Intel Celeron N4100 processor. Peakago is still not available, as Indiegogo backers are still waiting for their perks. So if you’re looking for an entry-level mini laptop NANOTE appears to be a better option as […]

Banana Pi BPI-F2P Industrial Control Board Adds PoE, RS-232 and RS-485 Interfaces

At the end of Last year, we covered Banana Pi BPI-F2S Industrial SBC powered by Sunplus SP7021 “Plus1” SoC with four Cortex-A7 core, an Arm A926 microprocessor, an 8051 core, as well as 128MB to 512MB built-in DDR3 RAM. The company has now unveiled Banana Pi BPI-F2P with the same processor and many of the same features, but with the addition of PoE support on one of the Fast Ethernet ports, as well as an RS-232 DB9 connector, and RS-485 terminal blocks. The expansion connector for an FPGA board found in BPI-F2S is however gone. Banana Pi BPI-F2P specifications: SoC – Sunplus SP7021 “Plus1” with a quad-core Cortex-A7 processor @ 1.0 GHz, one Arm A926 microprocessor, an 8051 core to handle I/Os, and 128MB or 512MB DDR3 DRAM. Storage – 8GB eMMC flash, microSD card slot Video Output – HDMI 1.4 output Camera I/F – MIPI CSI connector Connectivity – […]

Ingenic T31 AI Video Processor Combines MIPS & RISC-V Cores

Ingenic T31 MIPS & RISC-V Video Processor

Last week we asked “is MIPS dead?” question following the news that Wave Computing had filed for bankruptcy, two MIPS Linux maintainers had left, and China-based CIP United now obtained the exclusive MIPS license rights for mainland China, Hong Kong, and Macau. Ingenic is one of those Chinese companies that have offered MIPS-based processors for several years, but one commenter noted that Ingenic joined the RISC-V foundation, and as a result, we could speculate the company might soon launch RISC-V processors, potentially replacing their MIPS offerings. But Ingenic T31 video processor just features both with a traditional Xburst MIPS Core combines with a RISC-V “Lite” core Ingenic T31 specifications: Processors XBurst 1 32-bit MIPS core clocked at 1.5GHz with Vector Deep Learning accelerator based on SIMD128, 64KB + 128KB L1/L2 Cache RISC-V independent lite core System Memory – Built-in 512Mbit (64MB) or 1Gbit (128MB) DDR2 Storage – Quad SPI flash, […]

Ampere eMAG 64bit Arm Workstation Enables Native Arm Development

Over the last few years, several companies have come up with 64-bit Arm workstation to allow developers to test Arm code natively which may be important to avoid network delays or test applications requiring video or graphics. Those started to become available in 2018 from the relatively low-end 24-core Cortex-A53 Linaro “Synquacer” Developerbox to the much more powerful (and expensive) GIGABYTE ThunderXStation Workstation powered by up to two 32-core ThunderX2 processors. In the fall of 2019, SolidRun started to ship HoneyComb LX2K 16-core Arm Workstation motherboard with and NXP LX2160A 16-core Cortex-A72 processor that offers significantly more performance than the Linaro Box at a reasonable price ($750). While reading a recent Anandtech post with photos of an engineering sample, I found out Avantek was also offering the Ampere eMAG 64bit Arm Workstation powered by an Ampere eMAG 8180 32-core server processor. Ampere eMAG 64-bit Arm workstation specifications: SoC – Ampere […]
