• Cache
A memory component referred to by the processor, for faster and more efficient
processing. The processor accesses the cache before the RAM and storage devices,
because data transfers from the cache to the CPU are faster than data transfers
from the RAM or storage devices.
Many computers have a primary cache and a secondary cache. When searching for
information, the processor first refers to the primary cache. If it cannot find the
required information, it will then refer to the secondary cache.
See also blocking cache and non-blocking cache.
• 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.
• Composite synchronization
A synchronization signal made up of two components: one horizontal and one
vertical.
• Contiguous memory
A block of physical memory occupying a single, consecutive series of locations.
• DCF
Digitizer Configuration Format. A DCF defines the input data format and among
other things, how to accept or generate video timing signals, such as horizontal
synchronization, vertical synchronization, and pixel clock.
