Chapter 4: DSP Blocks in Stratix IV Devices
Stratix IV Operational Mode Descriptions
February 2011 Altera Corporation
36-Bit Multiplier
You can efficiently construct a 36 × 36 multiplier using four 18 × 18 multipliers. This
simplification fits conveniently into one half DSP block and is implemented in the
DSP block automatically by selecting 36 × 36 mode. Stratix IV devices can have up to
two 36-bit multipliers per DSP block (one 36-bit multiplier per half DSP block). The
36-bit multiplier is also under the independent multiplier mode but uses the entire
half DSP block, including the dedicated hardware logic after the pipeline registers to
implement the 36 × 36 bit multiplication operation, as shown in
The 36-bit multiplier is useful for applications requiring more than 18-bit precision;
for example, for the mantissa multiplication portion of single precision and extended
single precision floating-point arithmetic applications.
