INTRODUCTION
Network bandwidths have been increasing and Latencies through these networks have been decreasing. Unfortunately, applications have not been able to take full advantage of these performance improvements due to the many layers of user level and kernel level software that is required to get to the network. The Direct Access File System (or simply DAFS) developed by Microsoft, Compaq and Intel, significantly reduces the software overhead between a high performance CPU/memory subsystem, and a high performance network. Direct Access F ....etc

dma controller direct memory access using vhdl vlsi latest
Direct memory access (DMA) is a feature of modern computers that allows certain hardware subsystems within the computer to access system memory for reading and/or writing independently of the central processing unit. Computers that have DMA channels can transfer data to and from devices with much less CPU overhead than computers without a DMA channel.
Principle of DMA
DMA is an essential feature of all modern computers, as it allows devices to transfer data without subjecting the CPU ....etc

Abstract
The ordinary CDMA technology has the disadvantage of identifying the users using the appropriate signature of each user. Since many users tend to use the transmission media, there is always a chance for superimposition of signals that can cause interference in network.
The solution for this inconvenience comes in the form of interleaving which separates the users. This special form of CDMA technology offers some of the features of CDMA such as the dynamic channel sharing, mitigation of cross cell reference, asynchronous tran ....etc

DIRECT MEMORY ACCESS
introduction
An important aspect governing the Computer System performance is the transfer of data between memory and I/O devices.
Direct memory access (DMA) is a means of having a peripheral device control a processor's memory bus directly.
computer system with dma
Consider a typical system consisting of a CPU ,memory and one or more input/output devices as shown in fig. Assume one of the I/O devices is a disk drive and that the computer ....etc

Abstract:
The Direct Internet Access System (DIAS), jointly developed by Banyan Networks and TeNeT Group, liT Madras, allows telecom service providers to provide high bandwidth Internet access to residential and corporate . subscribers, in addition to voice services, without any changes to the existing cabling infrastructure. In contrast to current residential PSTN (Public Switched Telephone Network) and ISDN (Integrated Switched Digital Network) dial-up access, the DIAS provides an Always On Internet Access that is permanently available at t ....etc

Definition
The Idea Of Direct Memory Access
By providing circuitry to generate addresses and memory control signals independently of the processor we see that it is possible to improve performance considerably. All that is necessary is to provide a signal to tell the processor to remove itself from the bus so there is no contention on the memory control, address, or data lines.
This is the entire concept behind direct memory access (DMA). To complete our picture, it is important to note that there are actually several ways that DMA can be ....etc

Common rail direct fuel injection is a direct fuel injection system for petrol and diesel engines.
On diesel engines, it features a high-pressure (over 1,000 bar or 100 MPa or 15,000 psi) fuel rail feeding individual solenoid valves, as opposed to a low-pressure fuel pump feeding unit injectors (or pump nozzles). Third-generation common rail diesels now feature piezoelectric injectors for increased precision, with fuel pressures up to 3,000 bar (300 MPa; 44,000 psi).
In petrol engines, it is used in Gasoline direct ....etc
