ARM exec: Forget eight-core smartphone chips, just enjoy a SIX-PACK • The Register

ARM exec: Forget eight-core smartphone chips, just enjoy a SIX-PACK • The Register.

James Bruce from ARM explains that, in the tablet world, there are no use case for 8 core SoCs. However 8 is a lucky number for Chinese customers. The Exynos 5 octa is based on 4 cortex A15 combined with 4 A7 for instance. According to James Bruce 75% of the time, such a processor is either asleep or waiting for interrupts. So the actual need for the processing power is not proven.

Out of the 250 millions tablets shipped in 2013, 100 millions were shipped with a Chinese SoC inside.

 

Genode – An Exploration of ARM TrustZone Technology

This is a tutorial explaining in depth the way ARM TrustZone is structured, how it works and why. It also develops how the trusted environment communicates with the non trusted environment.

Open Source Software for Sensor Hub Applications from Sensor Platforms and ARM

Sensor Platform will provide a software framework open source under an Apache license for use onto ARM’s platform. The algorithms for sensor fusion, pedestrian walk count and dead reckoning will be included. The APIs to be compatible with Android KitKat will also be provided. The only question is what is Sensor Platforms business model?

ARM Moves to LLVM Open-Source for Future Compilers | EE Times

ARM moves to LLVM license type compile for ARMv8. The DS-5 toolsuite will stay in the same price range. It is the network, server and multicore applications which ignited this move. Linaro provides the GCC compiler for ARM today.

This move is actually a complete  turnaround for ARM.

Xilinx: An ‘All Programmable’ Strategy | Light Reading

This is a great high tech and business story at the same time. Xilinx has acquired RocketChips, Triscend, AutoESL Design Technologies: providing a software tool suite to easily program FPGA, Omiino: for optical transport, Sarance Technologies: a leader in MAC technologies, Modelware: for traffic management and packet processing, PetaLogix: to provide Linux solutions for MicroBlaze and PowerPC, Modesat Communications: Modem solution maker for microwaves.

Why is this clever? Because the networking segment where a combination of high speed data path and numerous protocols, packets sizes and shapes have to be dealt with is a great target for programmable logic.

Xilinx has identified this early enough to deploy a step by step M&A strategy which puts the company in the head of the race as a provider for network equipment manufacturers. When visionary high tech and savvy business people make a team, the results can be great.

Faster, cheaper, smaller: The state of the system-on-a-chip in 2014 | Ars Technica

The trend for 2014 for the SoC market is described here. It tells us about how 2014 is about adding more cores and controlling the power consumption. We do not necessarily agree with the opinion of the journalist. The market grows in the mid-range while volumes stagnate on the high range segment. The journalist believes very much in Nvidia, less in Intel and a little in Qualcomm when we would bet more on Qualcomm for their integrated approach and on Mediatek. We also believe Rockchip will be a key player. So in a nutshell after the race for the higher clock, now is the time for the race for the higher number of cores. Let the game begin.

AnandTech | ARM Partners Ship 50 Billion Chips Since 1991 – Where Did They Go?

ARM has communicated on the 50 billions cores sold since the beginning of its operations in 1991. This is huge. This article explains that most of them went to the mobile industry …. but not only.

What are the new emerging markets for ARM?

What would be a great next step?

The threshold of 50 billions cores shipped is really impressive. It is a symbol and a great achievement.

Linux mini-PC and JavaScript speed IoT development ·  LinuxGizmos.com

Kinoma mini-PC sponsored by Marvell.

We like very much this kind of platform. Why? The processor is dated, it is a CortexA8 base, however it consumed 2Watts. This is quite nice. Sensors can be added without a breadboard which is both a clean and elegant approach. The connectivity of the device is good, some sensors can be connected through the WiFi.

A complete software stack is delivered together with the board. We are not big fans of the claim ‘accessing sensor values through Javascript’ although we understand its value for application developpers.

Open question: why did Marvell go to Indiegogo to fund and sell the device?
