PULPino Open Source RISC-V MCU is Designed for IoT and Wearables

lowRISC is not the only open source processor project based on RISC-V instructions, as researchers at ETH Zurich university and the University of Bologna have developed PULPino open-source processor based on RISC-V instructions set, optimized for low power consumption, and targeting wearables and the IoT applications. PULPino is a single core processor derived from the PULP project (Parallel Ultra-Low-Power Platform) featuring a quad core RISC-V SoC with new RI5CY Signal Processing ISA extensions designed by the universities. The core has an IPC (instructions per cycle) close to 1, full support for the base integer instruction set (RV32I), compressed instructions (RV32C) and partial support for the multiplication instruction set extension (RV32M). PULPino also features peripherals such as I2S, I2C, SPI and UART. PULPino has already been taped out as an ASIC in UMC 65nm at the beginning of the year, but the RTL code be run on Xilinx Zynq-7010 powered Zedboard, […]

MK808B Pro Amlogic S905 Android TV Stick Unboxing and Teardown

MK808B Pro TV stick is the successor of the popular MK808B Plus and before that MK808B Android TV dongles with an upgrade to Amlogic S905 processor with 4K support. GeekBuying sent me a sample for evaluation, so I’ll start by checking the hardware before testing the device thoroughly in the full review. MK808B Pro Unboxing I received the stick in a package larger than I expected, but apparently about the same as the previous models (which I had not reviewed). But that’s because of the included accessories: a 5V/2A power supply, a USB cable, a mini USB OTG adapter, a mini HDMI to HDMI cable, and a user’s manual. Apart from the markings “MK808B PRO” and “4K Ultra HD”, the device looks the same as the older models. A mini USB port for power, and a USB 2.0 host port can be found on one end, with a micro SD […]

Rockchip PX3 and PX4 Processors Are Designed for Automotive Infotainment & Dashboards

Rockchip PX2 processor, similar to Rockchip RK3066 but targeting industrial and automotive applications, was launched in 2014. Rockchip now has at least two new member in their PX family with PX3 and PX4 specifically designed for automotive infotainment and car dashboards thanks to dual display support, at least according to one article on Elezine. Rockchip PX3 is definitely confirmed with its own page on Rockchip website, and features a quad core Cortex A9 @ 1.4 GHz with a Mali-400MP4 GPU, and while there’s no info about PX4 yet on the company website, the SoC should come with a quad core Cortex A53 processor @ 1.3 GHz with a Mali-T722 GPU, as well as HDMI 2.0 video output, and H.265 video decoding. The article also lists 7 key function of Rockchip solutions: “Quick startup and fast revert track” Navigation system with free updates HD video recording (car DVR) Advanced ADAS algorithm […]

Review of U4 Quad Hybrid Android Set-top box with DVB-T2/C and DVB-S2 Tuner

U4 Quad Hybrid is an Android 4.4 satellite, cable and terrestrial TV receiver powered by HiSilicon Hi3796M V100 quad core Cortex A7 supporting video decoding for H.264 and H.265 up to 4K @ 30 Hz. I’ve already taken a few pictures of the device and the board and tuner, shown how to easily configure another device or computer to stream live TV from this Android TV box, so today, I’ll write more about the Android and DVB parts both in terms of features and performance in the full review. First Boot, Settings and First Impressions I’ve started by connecting USB peripherals and cables: USB 3.0 hard drive to USB 3.0 port, USB keyboard, and RF dongles for MINIX NEO A2 Lite air mouse and Tronsmart Mars G01 gamepad, as well as Ethernet and HDMI cables, and the terrestrial and satellite antenna cables. The DVB-T2 connector is using an F-connector, so […]

Open Source Mali-200 / Mali-400 GPU Lima Driver Gets New Commits

The Lima driver, a project aimed at providing an open source driver for ARM Mali-400 and Mali-200 GPUs, was introduced 4 years ago, and after some reverse engineering work, a Quake 3 demo was showcase later in 2013 with an intermediate version of the Lima drivers. However, the main developer (libv) eventually lost interest or lacked time to further work, and the latest commit was made in June 9, 2013. But another developer (oklas) committed some code to limadriver-ng just a few days ago. But don’t get too excited, as the modifications are minor with some build fixes, some other Makefile modifications, and only one C file modified with 6 new lines of code. But maybe that’s just the beginning… We’ll see. Mali-400 GPU is now rather old, so why would somebody work on this? One explanation could be C.H.I.P and Pine A64 boards are both based on Allwinner SoCs […]
