Figure 19-2. Block Diagram: PRAM_CTL

Figure 19-2 above shows the address and data paths throughout the PRAM_CTL. d.width above

represents the parameterizable data width of the module which can be set to values of 64 or 32. t.width

(total width) and a.width (address width) are derived from the data width parameter. t.width is a

combination of the data width and 7 ECC bits for each 32 bits of data. a.width has a value of 17 bits for a

64 bit data path and 18 bits for a 32 bit data path.
