Volume Holograms

Holographic memory is currently attracting attention as a data storage system capable of achieving a data transfer rate of about 105~106105~106 times that of an optical disc such as Blu-ray disc. In conventional holographic memory, data is generally recorded by optical writing using volume holograms. However, a volume hologram has the problem not only that it is required to have high mechanical accuracy of a system and low coefficient of thermal expansion of a recording medium, because reconstruction tolerance is extremely low, but also that duplicating time efficiency is poor because whole data cannot be recorded at once. In this paper we proposed surface holographic memory that achieved a high data transfer rate, stable readout performance, and collective duplication by expressing holograms with fine surface asperity. Furthermore, the theoretical formulas of recording and reconstruction processes in the proposed system were derived and the reconstruction characteristics of the hologram were evaluated by numerical simulation. As a result, the proposed method generated reconstructed image readout with sufficient signal for a single page recording. However, the reconstructed image had noise, which was particular to a surface holographic memory.

Remote Client

In the work on the basis of Arduino Mega and the W5100 controller, a web server is built for graphical display of remote client data obtained from temperature, pressure, humidity sensors. The server program is written in the Arduino IDE development environment. The Ethernet library for the W5100 has been updated, which for Arduino IDE ver. 1.0.3, 1.0.5-r2 caused the server to hang. The possibility of using the Dygraphs library for graphical visualization of data obtained with sensors is shown. Written scripts for drawing graphics for the projected web server. The data transfer rate from the Arduino web server for various network controllers ENC28J60, W5100, W5500 for the Arduino IDE programming environment and UIPEthernet, Ethernet, Ethernet2 libraries was analyzed. It is shown that with the lowest speed the data is transmitted by the web server with the ENC28J60 controller - 3.3Kb/s, with the largest controller W5500 - 23.4Kbytes/s. It is noted that these servers do not support multithreaded work. Therefore, they can not be used to create miniature universal web servers for processing multiple requests simultaneously. The server considered in the work can serve only one request from one remote client. The speed parameters of data transfer for the server on the ATmega328p microcontroller (Arduino UNO) with the network controller ENC28J60 are analyzed. The server program is implemented in C language in the AVR Studio programming environment. A high data transfer rate of 140Kb/s and a possibility of multithreading are noted. It is established that with simultaneous transmission of three files to different clients, the total transmission speed reaches 120-130Kb/s, and for each client 40-50Kb/s. It is shown that the use of such a server to solve the problem of graphical representation of data from sensors is difficult due to the complexity of transferring software to other microcontrollers and the limited library for working with a microSD card. The operation of the server developed here for three years has shown high reliability of its operation. The paper discusses the creation of a web server on the Arduino, which is a modernized HTTP basic authentication. The upgrade consists in the fact that for authorization a password is used from the list of passwords that is selected by the user on the basis of the key sent by the server. With each new login to the server, the previous password becomes invalid. Presents a practical example of a web server on Arduino Mega, Ethernet controllers: enc28j60 and w5500.

Wireless Mobile

With the widespread popularity of wireless mobile devices, the demands of emerging applications have been proposed, such as video telephony and HD video play. The next generation of wireless mobile computing devices needs to have higher data transfer rate, more complex algorithms, as well as low power consumption. This paper gives out a variable-width SIMD processor architectures controller and data transfer module designing method. The controller designing focused on controlling the program flow and initializing the data transfer module. By simulating the architecture on Xilinx ISE Design Suite, the fundamental modules have been designed and tested. The results of simulation verify the correctness of the controller and data transfer module design.
