Glossary
• 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 or by increasing the clock frequency at which an interface or a
core operates (for example, increasing the DDR SDRAM clock frequency).
• BIOS
Basic Input/Output System . The interface between the operating system and the
hardware. It is also responsible for booting the operating system when a unit is
turned on.
• Bus
A pathway along which signals are sent, generally in two directions, for
communication data.
• 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 colors.
• CVBS
Composite Video, Blanking, and Sync . A composite analog video encoding which
encodes the luminance and chrominance video components into one signal.
• DCF
Digitizer Configuration Format . A file format that defines the input data format
and, for example, how to accept or generate video timing signals, such as horizontal
sync, vertical sync, and pixel clock.
Such files have a . dcf extension.
