Mediatek Helio X20 Processor to Features 10 Cores in Three Clusters

ARM first announced big.LITTLE processing on 2011, and since then we’ve seem several mobile processors providing two CPU clusters with “big” cores such as Cortex A15 or A57 and “LITTLE” core such as Cortex A7 and A53 to optimize performance and power consumption. With its latest Helio X20 (MT6797), Mediatek brings TINY.medium.huge processing with the first mobile processor using three CPU clusters, although a 3-level architecture has also been used before in Dhanush wearables SoC. The three clusters are divided as follows: TINY – Four ARM Cortex A53 core @ up to 1.4 GHz for best power efficiency medium – Four ARM Cortex A53 cores @ up to 2.0 GHz for a good performance / power balance huge – Two ARM Cortex A72 cores @ up to 2.5 GHz for maximum performance All three clusters are linked together and the memory bus via Mediatek Coherence System Interconnect (MCSI). Mediatek claims their […]

STMicro STM32F7 Series is the First ARM Cortex-M7 MCU Family

Right after ARM’s Cortex-M7 announcement, STMicro has listed STM32F7 MCU family based on the latest ARM core on their website. The family is comprised of 20 different MCUs with various flash size, packages, and with or without a crypto/hash coprocessor. The company expects their STM32F756xx microcontrollers to be used for motor drive and application control, medical equipment, industrial applications such as PLC, inverters, and circuit breakers, printers & scanners, alarm systems, video intercom, HVAC, home audio appliances, mobile applications, Internet of Things application, and wearable devices such as smartwatches. STM32F7 MCUs share the following key features: Cortex-M7 core @ 200 Mhz (1000 CoreMark/428 DMIPS) with L1 cache (4KB I-cache, 4KB d-cache) 320KBytes of SRAM with scattered architecture: 240 Kbytes of universal data memory a 16 Kbytes partition for sharing data over the bus matrix 64 Kbytes of Tightly-Coupled Data Memory (DTCM) for time critical data handling (stack, heap…) 16 Kbytes […]

Mediatek Smartphone and Tablet SoC Product Line (Mess) Explained

This week-end, I have been tipped about a $91 Mediatek MT8317 based 7″ Phablet, but I really did not know what to think about it as Mediatek seems to have so many SoCs, and really felt lazy trying to dig information about this. Yet, in the back of my head, I had decided to eventually make a post trying to clarifying Mediatek SoCs. This morning, I felt relieved not to have to spend hours investigating, as AndroidPC.es found an analyst paper doing just that, at least for recent and upcoming Mediatek processors. Mediatek Smartphone SoCs Roadmap MT6589 is certainly the most common SoC for cheap quad core smartphones, and starting this month, it will be available in MT6589M and MT6589T versions, the former with a weak video processing unit (VPU) and ISP, and GPU frequency, and the latter with higher GPU and CPU frequencies. Contrary to the table below, MT6589 […]

Kimdecent T21 mini PC Unboxing and Review

Androidpc.es has written a review for the low cost ($49) Kimdecent T21 dual core mini PC in Spanish, and I’ll provide a summary of the review in English below. Kimdecent T21 Unboxing Kimdecent T21 is an Android 4.1 HDMI TV Stick powered by Nufront NS115 dual core Cortex A9 processor. Check out my earlier post about Kimdecent T21 for specifications. The package comes with T21 mini PC, a power adapter with USB to micro USB cable, and a user manual in English. You can also watch  T21 Unboxing Video on YouTube. Kimdecent T21 User Interface & System Overview The user interface is a standard Android screen, albeit with power and volume buttons in the Status Bar. I don’t really find this interface very suitable for the TV, but you can always install your own launcher such as Android TV Launcher (apk), or other launcher apps available on Google Play. Beside […]
