Marvell Introduces ARMADA 1500 Ultra SoC for 4K STB with Vivante GC7000XS GPU

Marvell has just unveiled another STB SoC with ARMADA 1500 Ultra (88DE3218) with four ARM Cortex A53 cores, and instead of using Mali or PowerVR GPUs like many competitors, they integrated an octa core Vivante GC7000XS 3D GPU anda Vivante GL520 2D GPU into the chip. The SoC is designed for 4K Android set-top boxes from PayTV operators and STB manufacturers, supports 4K UHD 10-bit HEVC and VP9 video codecs, and embeds a security processor supporting conditional access systems (CAS) solutions from Verimatrix, Widevine, PlayReady, and DTCP-IP. Key features listed for ARMADA 1500 Ultra: 2160p60 10 bit HEVC & VP9 Video Decode + 1080 PiP + Trancoding concurrently Quad Core ARM A53 64-bit CPU @ up to 1.5 GHz (Up to 14K DMIPs) with 1MB L2 Cache 8 core GPU, 8 shader Vivante GC7000XS supporting OpenGL ES 1.1/2.0/3.0/3/.1, OpenCL 1.2 and DirectFB.

Zidoo D1 Android DVB-T2 Set-top Box is Powered by ALI M3733 SoC

We’ve already seen Android set-top boxes powered by ALi M3733 dual core Cortex A9 processor with either DVB-T2 or DVB-S2 tuners. Zidoo, the maker of Zidoo X9 Android HDMI player and recorder, have unveiled a new model based on ALi processor dubbed Zidoo D1 that will come with a DVB-T2 tuner, and they’ve also released a video giving a better glimpse of the user interface used in ALi M3733 media players. The hardware specs are very similar to Uyesee L100T2: SoC – ALi M3733 dual core Cortex A9 processor with a dual core Mali-400 GPU System Memory – 512 MB or 1GB DDR3 Storage – 4 or 8 GB NAND flash Video & Audio Output – HDMI 1.4 up to 1080p + 3.5mm AV jack Tuner DVB-T and DVB-T2 with male and female IEC 169-24 connectors for loop and output. Frequency – 104-862MHz (VHF/UHF) Demodulation – QPSK, 16QAM, 64QAM for DVB-T; […]

Wintel W8 Review – Dual Boot Android & Windows TV Box

Wintel W8 (aka Kingnovel K8) is an Intel Atom Z3735F mini PC inspired from Sunchip Wintel CX-W8 (the hardware is a little different), but instead of just running Windows 8.1, the device can dual boot Android 4.4 and Windows 8.1 with Bing. I’ve already taken pictures or torn down Wintel W8, so today, I’ll focus on the software part of the review, first checking dual boot functionality and Windows 8.1 briefly since it should be very similar to MeLE PCG03, before spending more time on Android as it’s my first Android Intel platform. Dual boot in Wintel W8 When you boot the device, you can select Android or Windows icon, with a 10 second timeout that will boot your latest choice. There’s no menu within Windows to start Android, and vice versa, so to dual boot you need to reboot first, and select the operating systems right after UEFI. The […]

Improve Mediatek MT6752 GPS Accuracy by Turning WiFi Off?

Mediatek smartphones used to have a terribly slow GPS fix, and it would often take over 10 minutes to get a fix if any, and one workaround was to enable Mediatek EPO. However, in my Iocean M6752 review, I found out GPS fix was not super fast even without Internet connection, but accuracy is quite a disaster as Nike+ Running screenshot below clearly shows. I’m running around a stadium so the shape should be elliptic…, but data point are all over the place. Since the review, I’ve kept using the smartphone with Nike+ Running, and each time it’s a disaster, and once the app even reported a 81 km for an actual 10 km run… I’ve also used Google Maps once or twice, and found accuracy to be poor as well. However, I usually leave Wi-Fi on, and for some reasons today, I decided to turn Wi-Fi off before driving […]

Variscite DART-MX6 is a Tiny SoM with Freescale i.MX6 SoC, Wi-Fi and Bluetooth

Variscite has unveiled what they claim to be the world’s smallest i.MX6 SoM with DART-MX6, a 50x20mm system-on-module featuring Freescale i.MX6 dual or quad processor, up to 1GB RAM, up to 32GB eMMC flash, as well as a wireless module for Wi-Fi and Bluetooth connectivity. Other small i.MX6 modules include TechNexion PICO-iMX6, or SolidRun microSoM found in Hummingbird board, and DART-MX6 has indeed the smallest area among the three. DART-MX6 specifications: SoC- Freescale i.MX6 dual or quad core Cortex A9 processor up to 800 MHz with Vivante GC2000 3D GPU System Memory – 512 to 1024 MB LPDDR2 (PoP) Storage – 4 to 32GB eMMC flash, 4KB I2C EEPROM Connectivity – Wi-Fi 802.11 a/b/g/n + MIMO, Bluetooth 4.0 BLE (TI WL183xMOD WiLink) Audio Codec – Texas Instruments TLV320AIC3106 Interfaces and I/Os via 2x 80-pin and 1x 50-pin board to board connectors Camera Interfaces – 1x CSI, 2x CPI Display – […]

$10 Digistump Oak ESP8266EX Board is Arduino Compatible, Connects to the Cloud, and More (Crowdfunding)

A few years ago, I wondered why adding Wi-Fi to Arduino had to be rather expensive ($40+), and why there weren’t any low cost and small form factor Wi-Fi boards for embedded applications. But we’re now in 2015, embedded is “dead” giving rise to IoT, and I’m left wondering how it’s possible to make IoT Wi-Fi modules that cheap, and whether people will ever stop churning out cheap Wi-Fi boards, as I’m flooded with such news weekly… So when I saw yet another ESP8266 board on Kickstarter I was about to dismiss it, but since it was made by Digistump, that has an active community with their other products like DigiSpark Pro or DigiX, I decided to have a closer look. Digistump Oak hardware specifications: MCU – Espressif ESP8266EX 32-bit microprocessor @ 80MHz (overclockable up to 160MHz) with 1MB ROM (~300KB available for user code), 64KB RAM, 512 bytes EEPROM […]

Tronsmart Draco H3 is a Low Cost HDMI TV Stick based on Allwinner H3 SoC

Allwinner H3 was unveiled as a quad core processor for 4K media players that would sell for less than $50, but so far devices like TVPP0030 are selling for an unattractive $80, but this may be about to change thanks to devices like Tronsmart Draco H3 HDMI TV stick that are expected to sell between $30 to $40 retail, possibly excluding shipping, and it would then compete against Amlogic S805 platforms such as MK808B Plus that only support 1080p video decoding and output. Preliminary specifications for Tronsmart Draco H3: SoC – Allwinner H3 quad core ARM Cortex A7 @ 1.5GHz with quad core Mali-400MP2 @ 600 MHz System Memory – 1 GB DDR3 Storage – 8 GB eMMC flash + micro SD slot Connectivity – 802.11 b/g/n Wi-Fi with external antenna, and Bluetooth 4.0 (AP6212 module) Video & Audio Output – HDMI 1.4 male connector up to 4K2K @ 30Hz, with […]

Wintel W8 Dual boot Android 4.4 + Windows 8.1 mini PC Unboxing

Last year, we were promised dual boot mini PC based on Intel that would run Windows 8.1 or Android 4.4, but finally companies decided against shipping a dual boot firmware, and simply loaded Windows 8.1 on their machines. Kingnovel sent me their K8 mini PC, better known as Wintel W8, based on Intel Atom Z3735F, and that can dual boot Windows 8.1 with Bing or Android 4.4. Today, I’ll go through the specs first, take some pictures of the device, and tear it down to have a closer look at the hardware, and in a separate post I’ll quickly check out Windows 8.1, before spending a bit more time on Android 4.4 to see how well or bad Android runs on Intel platforms. Kingnovel K8 / Wintel W8 specifications Hardware-wise the box has mostly the same boring specifications as almost any other Intel Atom Z3735F products on the market: SoC […]
