direct system output
1Direct Programming Interface — (DPI) is an interface which we use to interface System Verilog with foreign languages. These Foreign languages can be a C, C++, System C as well as others. DPI s consists of two layers: A System Verilog Layer and a Foreign language layer. Both… …
2Direct memory access — (DMA) is a feature of modern computers that allows certain hardware subsystems within the computer to access system memory independently of the central processing unit (CPU). Without DMA, the CPU using programmed input/output is typically fully… …
3Direct digital synthesis — (DDS) is an electronic method for digitally creating arbitrary waveforms and frequencies from a single, fixed source frequency. OverviewA basic DDS circuit consists of an electronic controller, a random access memory, a frequency reference… …
4Direct current — (red curve). The horizontal axis measures time; the vertical, current or voltage. Direct current (DC) is the unidirectional flow of electric charge. Direct current is produced by such sources as batteries, thermocouples, solar cells, and… …
5Direct torque control — (DTC) is one method used in variable frequency drives to control the torque (and thus finally the speed) of three phase AC electric motors. This involves calculating an estimate of the motor s magnetic flux and torque based on the measured… …
6Direct Graphics Access — is a plug in for the X Window System that allows client programs direct access to the frame buffer. Graphics hardware communicates via a chunk of memory called a frame buffer. This is an array of values that represent pixel color values on the… …
7Direct to disk recording — refers to methods by which digital audio and video are recorded to portable storage media such as hard drives and DVDs.Direct to disk can involve permanent or semi permanent non volatile recording media. Computer hard disk drives are erasable and …
8Direct binding — is a feature of the linker and dynamic linker on Solaris and OpenSolaris. It provides a method to allow libraries to directly bind symbols to other libraries, rather than weakly bind to them and leave the dynamic linker to figure out which… …
9Direct digital synthesizer — A DDS function generator. Direct Digital Synthesizer (DDS) is a type of frequency synthesizer used for creating arbitrary waveforms from a single, fixed frequency reference clock. Applications of DDS include: signal generation, local oscillators… …
10Direct coupling — In electronics, direct coupling (also called direct wired contact and conductive charging) is a way of interconnecting two circuits such that, in addition to transferring the AC signal (or information), the first stage also provides DC bias to… …
