82 / 432 page 4–2 Chapter 4: DSP Blocks in Stratix IV Devices Stratix IV DSP Block Overview Stratix IV Device Handbook February 2011 Altera Corporation Volume 1 Stratix IV DSP Block Overview 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 Table 4–1 lists the number of DSP blocks for the Stratix IV device family.
