ispGDX2 Family Data Sheet
6
The four data inputs to the 4:1 MUX come from the GRP. The output of this MUX connects to the output register. A
fast feedback path from the MUX to the GRP allows wider MUXes to be built. Table 2 summarizes the various MUX
sizes and delay levels.
Table 2. MUX Size Versus Internal Delay
Figure 3. ispGDX2 Family MRB
Control Array
The control array generates control signals for the 16 MRBs within a GDX Block. The true and complement forms
of 32 inputs from the GRP are available in the control array. The 20 NAND terms can use any or all of these inputs
to form the control array outputs. Two AND terms are combined with a NOR term to form Set/Reset and OE sig-
nals. Figure 4 illustrates the control array.
