INTEGRATION OF BASIC
COMPONENTS
The choice of how to integrate the four basic
components is an important step in designing a
graphics application. To make the choice, the designer
needs to understand the types of combinations of these
basic components that are possible in the form of ICs.
There are four types of possible combinations, as
illustrated in Figure 8 .
Table 2 lists the advantages and disadvantages of the
four combinations of the basic components.
