firmware The program or specific software instructions that have been more

or less permanently burned into an electronic component, such as a

ROM (read-only memory) or an EPROM (erasable programmable

read-only memory).

frame One complete television picture frame consists of 525 horizontal

lines with the NTSC system. One frame consists of two Fields.

graphics controller On EGA and VGA, a section of circuitry that can provide hardware

assist for graphics drawing algorithms by performing logical

functions on data written to display memory.

HAL Hardware Abstraction Layer. The lower level hardware interface

module of the Windows NT operating system. It contains platform

specific functionality.

hardware A computing system is normally spoken of as having two major

components: hardware and software. Hardware is the term used to

describe any of the physical embodiments of a computer system,

with emphasis on the electronic circuits (the computer) and

electromechanical devices (peripherals) that make up the system.

HCT Hardware Conformance Test. A test used to ensure that both

hardware and software conform to the Windows NT interface.

HAWK The next generation ASIC which combines the functionality of the

previous Falcon and Raven ASICs.

interlaced A graphics system in which the even scanlines are refreshed in one

vertical cycle (field), and the odd scanlines are refreshed in another

vertical cycle. The advantage is that the video bandwidth is roughly

half that required for a non-interlaced system of the same resolution.

This results in less costly hardware. It also may make it possible to

display a resolution that would otherwise be impossible on given

hardware. The disadvantage of an interlaced system is flicker,

especially when displaying objects that are only a few scanlines

high.
