Processor Cortex-A72

03.02.2015

The British company ARM Holdings introduced a typical processor for mobile devices in 2016 - Cortex-A72. The developer claimed that the Cortex-A72 is the fastest mobile "system on a chip" ever created. It is 50 times faster than the processors in smartphones released five years ago.

Cortex-A72 will run 3,5 times faster than 2014 processors and consume 4 times less power. Higher performance will be provided through a number of microarchitectural improvements and the transition to a new technological norm - 16 nm. The current norm is 28 nm.

The processor will be able to operate at frequencies up to 2,5 GHz. It will be 64-bit.

Primary destinations: Top-of-the-line smartphones, tablet phones, enterprise networking equipment, servers, wireless networking equipment, digital TV, and autonomous driving systems for vehicles.

Cortex-A72 will be able to work on ARM's big.LITTLE technology. It involves combining two processors with different cores to perform tasks of a different plan - for example, executing operating system tasks and running a racing simulator. big.LITTLE will allow Cortex-A72 cores to be combined with Cortex-A53 cores. The accompanying processor runs at a lower frequency and consumes less power to extend battery life.

In addition to the Cortex-A72, the company introduced the CoreLink CCI-500 inter-core technology. It is she who will be responsible for the connection of different types of cores in dual-processor configurations. Compared to the CoreLink CCI-400 technology used today, it offers a 30% faster memory transfer rate.

Growth in performance of smartphones based on ARM architecture in 2014-2016.

Finally, ARM Holdings has announced a new generic graphics controller, the Mali-T880. The company compares it to today's Mali-T760 solution. The indicators are as follows: productivity is 1,8 times higher, energy consumption is 40% lower. Mali-T880 can include from one to 16 cores. The core frequency is 850 MHz. The manufacturing process is similar to Cortex-A72 - 16 nm.

The company notes that the Mali-T880 is well suited for processing complex 3D graphics and 4K content.

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

Virtual Solis plans to build large photovoltaic panels in orbit, using Starship to deliver the necessary equipment. However, one of the key challenges ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

When Music Kills 05.12.2012

According to American statistics, over the past six years, with the spread of MP3 players, the frequency of cases of pedestrians with headphones getting under the wheels has tripled. In 2004, 16 people died because of passion for music, and in 2011 - 47. Two-thirds of those killed or injured were young men, who are most inclined to listen to music on the road. They did not hear any beeps or the noise of an approaching car or train. In addition, loud music weakens attention to what a person sees around him.

You should also not talk on the go on a mobile phone. Of the 6000 Finns surveyed, 14% admitted that, carried away by a conversation, they can stumble on the stairs, "drive" into a lamppost or almost get hit by a car.
