Device
Each Stratix IV device has two to seven columns of DSP blocks that implement
multiplication, multiply-add, multiply-accumulate (MAC), and dynamic shift
functions efficiently. Architectural highlights of the Stratix IV DSP block include:

High-performance, power optimized, fully registered, and pipelined
multiplication operations
Natively supported 9-, 12-, 18-, and 36-bit wordlengths
Natively supported 18-bit complex multiplications
Efficiently supported floating-point arithmetic formats (24-bit for single precision
and 53-bit for double precision)
Signed and unsigned input support
Built-in addition, subtraction, and accumulation units to combine multiplication
results efficiently
Cascading 18-bit input bus to form the tap-delay line for filtering applications
Cascading 44-bit output bus to propagate output results from one block to the next
block without external logic support
Rich and flexible arithmetic rounding and saturation units
Efficient barrel shifter support
Loopback capability to support adaptive filtering
