DSP Block Overview
Arria II Device Handbook Volume 1: Device Interfaces and Integration
Arria II GX devices have two to four columns of DSP blocks, while Arria II GZ
devices have two to seven columns of DSP blocks. These DSP blocks implement
multiplication, multiply-add, multiply-accumulate (MAC), and dynamic shift
functions. Architectural highlights of the Arria II DSP block include:

High-performance, power-optimized, fully registered, and pipelined
multiplication operations
Natively supported 9-bit, 12-bit, 18-bit, and 36-bit word lengths
Natively supported 18-bit complex multiplications
Efficiently supported floating-point arithmetic formats (24 bits for single precision
and 53 bits for double precision)
Signed and unsigned input support
Built-in addition, subtraction, and accumulation units to efficiently combine
multiplication results
Cascading 18-bit input bus to form 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
