Chapter 4: Embedded Multipliers in the Cyclone III Device Family  
Embedded Multiplier Block Overview  
Embedded Multiplier Block Overview  
Figure 4–1 shows one of the embedded multiplier columns with the surrounding logic  
array blocks (LABs). The embedded multiplier is configured as either one 18 × 18  
multiplier or two 9 × 9 multipliers. For multiplications greater than 18 × 18, the  
Quartus® II software cascades multiple embedded multiplier blocks together. There  
are no restrictions on the data width of the multiplier, but the greater the data width,  
the slower the multiplication process.

Note to Table 4–1:  
(1) These columns show the number of 9 × 9 or 18 × 18 multipliers for each device. The total number of multipliers for each device is not the sum  
of all the multipliers.
