58 Appendix D: Glossary

•ASIC

Application-specific integrated circuit. An integrated circuit custom-made to meet

the requirements of a specific application. It integrates several digital and/or analog

functions into a single die. This results in a reduction in cost, board area, and

power consumption, while improving performance when compared to an

equivalent implementation using off-the-shelf components.

•Band

One of the surfaces of a buffer. A grayscale image requires just one band. A color

image requires three bands, one for each color component.

•Bandwidth

A term describing the capacity to transfer data. Greater bandwidth is needed to

sustain a higher transfer rate. Greater bandwidth can be achieved, for example, by

using a wider bus.

•Bit

A digit of a binary number. Images are described as 1-bit, 8-bit, 16-bit, etc. The

numbers indicate the bits available to store the value of each pixel in the image.

•Bus

A pathway along which signals are sent, generally in two directions, for

communication of data.

• Color component

One of the components that make up a color space. Typically, each component

of a color image is stored in a separate band of a multi-band buffer.

• Color space

A color space is a way of representing and describing the complete range of

perceived colors. A number of color spaces have been developed. Common color

spaces are RGB and HSL. Both describe the same range of perceivable colors.
