Caustic 2500 - serial ray tracing accelerator

23.01.2013

The topic of imaging by ray tracing has been covered by various sources with constant frequency for many years. However, if we believe the Imagination Technologies representatives and their booth at CES, in the near future we will finally see serious shifts in this direction. To implement them, the company introduced a specialized accelerator - Caustic Series2 OpenRL (recall that Imagination Technologies acquired Caustic Graphics precisely for the sake of developments in the field of ray tracing technology). Representatives of the company assured that the exhibition was already a serial sample (ASIC), and not a device based on programmable gate arrays (FPGA).

Actually, the line of accelerators will consist of two models: Caustic 2500 and Caustic 2100. The older model will be a dual-processor card (two RT2 chips) with 16 GB of memory. The peculiarity of the novelty is that it does not need fast memory such as GDDR5, but completely manages DDR2.

The Caustic 2100 carries one RT2 chip and 8 GB of memory. The undoubted trump card is the simple integration of the Caustic Visualizer software into existing specialized software (AutoDesk Maya 2013, 3ds max).

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, ... >>

MAXIM solutions for data transmission over the power grid 30.04.2010

MAX2990 is a PLC modem that allows organizing half-duplex asynchronous data transmission at speeds up to 100 kbps in the carrier frequency range of 10...490 kHz using the existing electrical network.

The use of digital OFDM modulation provides a reliable connection in low-quality networks under conditions of impulse noise and group signal delays. It also avoids the use of equalizers to compensate for frequency selective signal attenuation. Anti-jamming data coding makes the MAX2990 one of the most reliable PLC modems for industrial applications. The MAX2990 combines both a PHY layer and a MAC layer implemented on a 16-bit RISC microcontroller with a MAXQ core.

The built-in flash memory for storing the MAC code and user program is 32 kB, the amount of RAM for data storage is 8 kB. The microcircuit contains a real-time clock, as well as timers with support for PWM mode. Interfaces are provided for communication with the applied microcontroller: UART, SPI, I2C. Debugging of the program code is carried out via JTAG. MAX2991 is an analog front-end for use with the MAX2990 PLC modem.

The transmitting part of the microcircuit performs the input of the OFDM signal into the line and includes an IIR filter, a 10-bit DAC, a configurable low-pass filter and a line pre-driver. The receiving part amplifies and filters the signal and consists of a low-pass filter, a 2-stage AGC with a dynamic range of 60 dB, and a 10-bit ADC. The connection to the MAX2990 is via a serial interface.
