New digital signal processors based on 90nm technology

21.06.2005

FREESCALE SEMICONDUCTOR has released the new MSC8122 and MSC8126 digital signal processors based on 90nm technology.

A feature of the processors are four computing cores on one substrate. With low power consumption, the new chips operate at clock speeds up to 500 MHz per core and perform up to 8 gigabytes of multiply and accumulate operations with a power dissipation of just 2 watts.

The scope of new DSPs is unusually wide: processing of audio and video information, packet telephony, faxes and modems. The company is the world's second largest manufacturer of digital signal processors.

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 ... >>

Energy from space for Starship 08.05.2024

Producing solar energy in space is becoming more feasible with the advent of new technologies and the development of space programs. The head of the startup Virtus Solis shared his vision of using SpaceX's Starship to create orbital power plants capable of powering the Earth. Startup Virtus Solis has unveiled an ambitious project to create orbital power plants using SpaceX's Starship. This idea could significantly change the field of solar energy production, making it more accessible and cheaper. The core of the startup's plan is to reduce the cost of launching satellites into space using Starship. This technological breakthrough is expected to make solar energy production in space more competitive with traditional energy sources. 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, ... >>

print robot 27.11.2015

To XNUMXD print a floating shark-shaped microrobot, researchers at the University of California at La Jolla, led by professors Chen Shaochen and Joseph Vann, used a microelectromechanical device. It consists of two million mirrors, each of which is equipped with its own drive.

On command, the drives give each mirror the desired tilt, and the beam of ultraviolet light falling on them is broken into pieces so that each new beam illuminates the desired point. At this point, the photosensitive liquid solidifies, in this case it was a polyethylene glycol diacrylate hydrogel. At the same time, many tiny figurines are being printed.

But that's not all. The print comes in layers, so by adding new fluids and removing old ones, you can change the composition of the figurine. In particular, platinum nanoparticles were embedded in the tail of a microshark measuring 120x30 µm, and iron oxide in the nose. Platinum decomposes hydrogen peroxide (namely, experimental fish swam in its solution) and ensures their movement; magnetic particles in the nose allow this movement to be controlled.

In addition, polydiacetylene nanogranules were included in the upper layer of the fish - this substance binds to bee venom molecules - and a dye that glows red when interacting with the venom. Having launched the fish into a solution containing peroxide and poison, the researchers were convinced of their success: the fish quickly absorbed the latter and lit up.

Now, with the help of other nanoparticles in the tail, it is necessary to teach the fish to use the energy from the components of biological fluids, and then they will serve as sensors for dangerous substances or drug delivery vehicles.
