I’ve been using Vernee Apollo Lite smartphone with a Mediatek Helio X20 deca-core ARM Cortex A72/A53 processor coupled with an ARM for a little over a year. Recently, I’ve received Xiaomi Mi A1 smartphone for a Qualcomm Snapdragon 625 SoC featuring eight ARM Cortex A53 cores and an Adreno 506 GPU. In theory, the latter is a downgrade, and the Xiaomi phone is indeed quite slower in Antutu with overall score of 60,161 points against 85,840 points in the Mediatek phone. 3D graphics performance is also lower with 12,849 vs 17,828 points. Both smartphone have the same resolution (1920×1080), so it’s a little confusing to be told you’d “better to play games in low quality mode” for the Mediatek phone, and “game performance is mid-level” for the Snapdragon one. But anyway Helio 20 should work better in 3D games than Snapdragon 625 if we are to believe the numbers. Most […]

Microsoft is Working with Mediatek on Project Sopris Secure WiFi MCU
There are serious security issues with the Internet of Things at all levels: hardware, software, network, and end-users. Microsoft Research NExT Operating Systems Technologies Group has been tasked with “exploring the goal of securing the vast number of low cost Internet connected devices coming online” with Project Sopris. They have shared their first technical report that identifies “seven properties of highly secure devices”, and describes their experiments towards designing microcontroller based prototype devices adapted from Mediatek MT7687 MIPS microcontroller, and exhibiting those seven properties. The seven properties identifies by Microsoft team include: Hardware-based Root of Trust – Unforgeable cryptographic keys generated and protected by hardware. Physical countermeasures resist side-channel attacks. Small Trusted Computing Base – Private keys stored in a hardware-protected vault, inaccessible to software. Division of software into self-protecting layers. Defense in Depth – Multiple mitigations applied against each threat. Countermeasures mitigate the consequences of a successful attack on […]
