ARM has unveiled the new ARM Cortex-A72 processor which they expect to be the standard SoC in mobile devices hitting the marketplace in 2016. Their claim is that it is the highest performing CPU technology available for developing mobile SoCs today. In target configurations, the Cortex-A72 processor is said to deliver CPU performance 50X greater than the leading smartphones from just five years ago.
The ARM premium mobile experience IP suite also offers a significant graphics upgrade offering users up to 4K120fps resolution. Alongside the Cortex-A72 processor is the new CoreLink CCI-500 interconnect and the new Mali-T880 GPU, ARM’s highest performing and most energy-efficient mobile GPU, along with Mali-V550 video and Mali-DP550 display processors. To further ease chip implementation, the suite also includes ARM POP IP for the leading-edge TSMC 16nm FinFET+ process.

Toshiba has added two new products to their ARM® Cortex®-M4F based TX04 series microcontrollers. The TMPM470FDFG and TMPM475FDFG are both capable of operating two brushless DC motors simultaneously.
The new microcontrollers aim to satisfy ever-increasing demand for more energy efficient motors and incorporate vectoring technology to ensure efficient motor control. The TMPM475FDFG also integrates a CAN (Controller Area Network) controller which is required for use in specialist factory automation systems. Both chips are ideal for a wide range of uses ranging from industrial applications to use in home appliances, such as washing machines, fridges and air-conditioning units.
The TMPM470FDFG and TMPM475FDFG are based upon the high-performance ARM® Cortex®-M4F and can operate at up to 120MHz. They incorporate two modules, each containing a programmable motor drive, 12-bit AD converter and vector engine, ensuring the efficient and simultaneous operation of two brushless DC motors from a single chip.

ARM PRO MINI is a small barebone open source ARM M0 microcontroller board that is great for quick prototyping and as a starting point for your own ARM based custom designs. It was designed and named after the venerable Arduino Pro Mini and it is an excellent stepping stone for makers and hobbyists ‘graduating’ from Arduino to the ARM architecture.

AtmelCorporation have announced two additions to their SAM G series of ARMCortex-M4-based MCUs. The two latest models are designated the SAM G54 and SAM G55. They feature high performance (up to 120MHz), low-power (102 µA/MHz in active mode, down to 5 µs wake-up) and tiny outline (as small as 2.84 x 2.84mm). Both are targeted at IoT applications and include all the features of the current SAM G family of devices including an Atmel | SMART ARM Cortex-M4 MCU + FPU (floating point unit) together with integrated sensor fusion algorithms.

Evaluation samples of STMicroelectronics’ STM32F446 range of MCUs are now available. These devices feature ARM Cortex-M4 based processing units with compact 256 or 512 KB on-chip Flash options and 128KB RAM with built-in memory-extension interfaces, extended connectivity and communication capabilities.
The MCUs use ST’s proprietary ART Accelerator, smart architecture, advanced Flash technology and an embedded ARM Cortex-M4 core to achieve a performance of 225 DMIPS and 608 CoreMark at 180 MHz executing from embedded Flash.
The interface capabilities allow simultaneous communication via multiple interfaces which cater for interactive industrial, scientific, medical, and Internet-of-Things (IoT) applications, while the advanced process technology, together with dynamic voltage scaling, extensive clock gating and flexible sleep modes offer significant power savings.

What is seeing without feeling? The field of Virtual Reality has recently been gaining much attention, with the Oculus Rift and Google Cardboard paving the path of visualizing a world that is not physically there. But what if the virtual reality experience could be enhanced by incorporating tactile sensing? The Haptic Glove we developed accomplishes just that – without seeing the physical structure of the object, you will still be able to feel the presence of virtual objects.
The goal of the project is to create an exoskeleton on the forearm arm that provides tactile perception for the user. The volume of the virtual object will be emulated based on the intensity of a light source that is placed inside a black box. Depending on the relative brightness of the source to the phototransistors that are mounted onto the exoskeleton, a distance between the user’s hand and the light source can be determined. By varying the brightness of the LED light source, the size of the virtual object will vary. To provide the tactile perception, servos mounted on the exoskeleton provides a pulling force, preventing the user’s fingers from reaching closer to the light source. In addition to the resistive force that act against the fingers’ movement, there are also flat surfaces at the tips of the exoskeleton that will flip up to make contact with the user’s fingers, which actually provides the sense of touching a real object.
