Figure 20-1 General Structure of the DSP
Each unit has one or more signal inputs (denoted by I). Most units have at least one
signal output (denoted by S). Any input I can be connected to any signal output S. In
addition to the signals shown in figure 20-1 there is also the signal S
useful at signal summation points. Table 20-1 lists the available signals within the INCA-
D according to their reference points. The 5-bit code for each signal in Table 20-1 is the
binary representation of the signal number.
