Hardware Abstraction Layer - HAL

HAL is Microsoft's abbreviation for the Hardware Abstraction Layer, the technology and drivers that let the Windows NT, 2000, and XP operating systems communicate with your PC's hardware. HAL is one of several features--along with the NT file system (NTFS) that replaced the much less secure MS-DOS--that make NT-based operating systems more secure and reliable than Windows 95, 98, and Me.

HAL prevents applications from directly accessing your PC's system memory, C ....etc

VHDL (VHSIC Hardware Description Language) is a language for describing hardware. Its requirement emerged during the VHSIC development program of the US Department of Defense. The department organized a work shop in 1981 to lay down the specifications of a language which could describe hardware at various levels of abstractions, could generate test signals and record responses, and could act as a medium of information exchange between the chip foundries and the CAD tool operators. However, due to military restrictions, it remained classified ti ....etc

HARDWARE BASED EDGE DETECTION

INTRODUCTION:
Edge detection is fundamental tool used in most image processing applications to obtain information from the frames before feature extraction and object segmentation. This process detects outlines of an object and boundaries between objects and the background in the image. Beyond that, Edge Detection refers to the process of identifying and locating sharp discontinuities in intensities in an image. The discontinuities are abrupt changes in pixels intensity which characterize boundaries of objects ....etc

HARDWARE IMPLEMENTATION AND ANALYSIS OF MD5

Abstract:- Hardware implementation aspects of the MD5 hash algorithm are discussed in this paper. A general architecture for MD5 is proposed and several implementations are presented. An extensive study of effects of pipelining on delay, area requirements and throughput is performed, and finally certain architectures are recommended and compared to other published MD5 designs. Hash algorithms are used widely in cryptographic protocols and Internet communication in general. Several widely used hash ....etc

Using a GPS to navigate, a guard locates a car theft and utilizes vehicle tracking that is, at present, widely employed. In this paper the terminal device using a microcontroller combines a GPS and a GSM/GPRS to make a portable and remote controlling device, and an embedded server is used as a transfer location server. In this way one accomplishes real-time vehicle trajectory monitoring. Clients can remotely monitor a vehiclepsilas position anywhere. Besides, as we have designed the remote monitoring using a virtual comport to combine the exist ....etc

Bluetooth is a common thing in the modern world. However it is very useful to transfer data from one device to another. But this requires two Bluetooth devices which are very expensive. The aim of our project is to make wireless data logger. Details of the application end system are stored in memory. Whenever the remote system wants to download the application end system details, the remote system has to send corresponding command to end system through radio frequency. According to command the application end system send details of system throu ....etc

Acceleration hardware

Acceleration hardware refers to devices that speed up data communications, storage and retrieval, encryption and decryption, mathematical operations, graphics, and Web page viewing. Acceleration hardware can consist of an individual integrated circuit (also called an IC or chip), a printed circuit card, or a self-contained system.

A NAS accelerator is a printed circuit card that offloads TCP/IP processing from a microprocessor. This can reduce latency, increase throughput, ....etc

Real-Time Positioning Technology Fleet management system is a rapid growing industry. This system helps institutions to manage vehicle fleet efficiently and effectively through smart allocation of resources. In this project, an intelligent fleet management system which incorporates the power of concurrent Global Positioning System (GPS) and Global System for Mobile Communications (GSM) real-time positioning, front-end intelligent and web-based management software is proposed. In contrast to systems which depend solely on GPS positioning, the pr ....etc

JHDL (Java Hardware Description Language) is a low level hardware description language, focused primarily on building circuits via an Object Oriented approach that bundles collections of gates into Java objects. Implemented as a toolset and class library on top of the Java programming language, its primary use is for the design of FPGAs. Particular attention was paid to supporting the Xilinx series of chips.
When the design is ready to be placed in a fabric, the developer simply generates an EDIF netlist and imports it into his favorite toolki ....etc
