Pipelining is the concept of overlapping of multiple instructions to perform their operations to optimize the time and ability of hardware units. This paper presents the design and implementation of 6 stage pipelined architecture for High performance 64-bit Microprocessor without Interlocked Pipeline Stages (MIPS) based Reduced Instruction set computing (RISC) processor. In this work, combining efforts of pre-fetching unit, forwarding unit, Branch and Jump predicting unit, Hazard unit are used to reduce the hazards. Low power unit is used to minimize the power.

The development of processors with sundry suggestions have been made regarding a exactitude definition of RISC, but the prosaic concept is that such a computer has a small set of simple and prosaic instructions, instead of an outsized set of intricate and specialized instructions. This project proposes the planning of a high speed 64 bit RISC processor. The miens of this processor consume less power and it contrives on high speed. The processor comprises of sections namely Instruction Fetch section, Instruction Decode section, and Execution section. The ALU within the execution section comprises a double-precision floating-point multiplier designed during a corollary architecture thus improving the speed and veracity of the execution. All the sections are designed using Verilog coding. Monotonous instruction format, cognate prosaic-purpose registers, and pellucid addressing modes were the other miens. RISC exemplified as Reduced Instruction Set Computer. For designing high-performance processors, RISC is considered to be the footing. The RISC processor has a diminished number of Instructions, fixed instruction length, more prosaic-purpose register which are catalogued into the register file, load-store architecture and facilitate addressing modes which make diacritic instruction execute faster and achieve a net gain in performance. Thus the cardinal intent of this paper is to consummate the veridicality by devouring less power, area and with merest delay and it would be done by reinstating the floating-point ALU with single precision section by floating- point double precision section. Video processing, telecommunications and image processing were the high end applications used by architecture

The main objective of this work is to implement a 32-bit pipelined RISC processor without interlocking stages. It is developed by S.I.M.E (Single Instruction Multiple Execution) that is with single instruction scheme more executions can be done and is based on VLIW(Very Long Instruction Word) architecture processing is an optimal choice in the attempt to obtain high performance level in Embedded Systems. In VLIW based architecture, the effectiveness of the processor depends on the ability of compilers to provide sufficient instruction level parallelism (ILP). The processor has been designed with VHDL, synthesized using Xilinx tool.

Разработана методика, обеспечивающая полный спектр организации работ по программированию микроконтроллера MDR32F9Q2I, которая позволяет получить, в частности, системы управления и мониторинга источников вторичного электроснабжения. Программирование микроконтроллера, построенного на базе высокопроизводительного процессорного RISC ядра ARM, производилось в интегрированной среде разработки Eclipse IDE в операционной системе Windows 10 Pro. Интегрированная среда разработки Eclipse выбрана как наиболее удобная и доступная среда, поддерживает всевозможные типы языков программирования и непрерывную компиляцию. В настоящее время 16- и 32-битные микроконтроллеры быстро набирают популярность в сфере промышленных задач. Их применение обусловлено постоянно возрастающей сложностью задач, жесткими требованиями к производительности интегрируемых контроллеров управления, необходимостью иметь в электронных устройствах развитые органы пользовательского управления. Представленный стенд для моделирования, использующий интерфейсный мост между шинами I2C и 1-Wire - DS2482-100, преобразует протоколы между управляющим I2C микроконтроллером (мастером) и ведомыми 1-Wire устройствами, а также контролирует скорости нарастания и уменьшения напряжения в линии. Основой для написания класса DS2482 являются заголовочные файлы Arduino.h и OneWire.h, которые находятся в свободном доступе In this article, we developed a technique that provides a full range of organization of works on programming the MDR32F9Q2I microcontroller, which allows you to obtain control and monitoring systems for secondary power supply sources. The microcontroller based on the high-performance ARM RISC processor core was programmed in the Eclipse IDE on the Windows 10 Pro operating system. We chose the Eclipse integrated development environment as the most convenient and accessible environment, it supports all kinds of programming languages and continuous compilation. Currently, 16- and 32-bit microcontrollers are rapidly gaining popularity in the field of industrial tasks. Their use is due to the ever-increasing complexity of tasks, stringent requirements for the performance of integrated controllers, the need to have advanced user controls in electronic devices. We present a simulation stand that uses an interface bridge between the I2C and 1-Wire buses - DS2482-100, converts protocols between the I2C microcontroller (master) and 1-Wire slaves, and also controls the voltage rise and fall rates in the line. The basis for writing the DS2482 class is the Arduino.h and OneWire.h header files, which are freely available

Electron Energy Loss

A double focusing magnetic spectrometer has been constructed for use with a field emission electron gun scanning microscope in order to study the electron energy loss mechanism in thin specimens. It is of the uniform field sector type with curved pole pieces. The shape of the pole pieces is determined by requiring that all particles be focused to a point at the image slit (point 1). The resultant shape gives perfect focusing in the median plane (Fig. 1) and first order focusing in the vertical plane (Fig. 2).

One of the most important requirements for a high-performance EM, especially an analytical EM using a fine beam probe, is to prevent specimen contamination by providing a clean high vacuum in the vicinity of the specimen. However, in almost all commercial EMs, the pressure in the vicinity of the specimen under observation is usually more than ten times higher than the pressure measured at the punping line. The EM column inevitably requires the use of greased Viton O-rings for fine movement, and specimens and films need to be exchanged frequently and several attachments may also be exchanged. For these reasons, a high speed pumping system, as well as a clean vacuum system, is now required. A newly developed electron microscope, the JEM-100CX features clean high vacuum in the vicinity of the specimen, realized by the use of a CASCADE type diffusion pump system which has been essentially improved over its predeces- sorD employed on the JEM-100C.

In the design engineering of high performance electromagnetic lenses, the direct conversion of electron optical design data into drawings for reliable hardware is oftentimes difficult, especially in terms of how to mount parts to each other, how to tolerance dimensions, and how to specify finishes. An answer to this is in the use of magnetostatic analytics, corresponding to boundary conditions for the optical design. With such models, the magnetostatic force on a test pole along the axis may be examined, and in this way one may obtain priority listings for holding dimensions, relieving stresses, etc..The development of magnetostatic models most easily proceeds from the derivation of scalar potentials of separate geometric elements. These potentials can then be conbined at will because of the superposition characteristic of conservative force fields.
