You can configure each DSP block during compilation as independent three 9 x 9, two 18 x 18, or one 27 x 27  
multipliers. Using two DSP block resources, you can also configure a 36 x 36 multiplier for high-precision  
applications. With a dedicated 64 bit cascade bus, you can cascade multiple variable-precision DSP blocks  
to implement even higher precision DSP functions efficiently.
