Table 4–1 shows that the largest Stratix IV DSP-centric device provides up to 1288
18 × 18 multiplier functionality in the 36 × 36, complex 18 × 18, and summation
modes.
Each DSP block occupies four LABs in height and can be divided further into two half
blocks that share some common clock signals, but are for all common purposes
identical in functionality. Figure 4–1 shows the layout of each DSP block.
