Stratix Device Handbook, Volume 1
Table 2–14
Multiplier
The multiplier supports 9 × 9-, 18 × 18-, or 36 × 36-bit multiplication. Each
DSP block supports eight possible 9 × 9-bit or smaller multipliers. There
are four multiplier blocks available for multipliers larger than 9 × 9 bits
but smaller than 18 × 18 bits. There is one multiplier block available for
multipliers larger than 18 × 18 bits but smaller than or equal to 36 × 36
bits. The ability to have several small multipliers is useful in applications
such as video processing. Large multipliers greater than 18 × 18 bits are
useful for applications such as the mantissa multiplication of a single-
precision floating-point number.
The multiplier operands can be signed or unsigned numbers, where the
result is signed if either input is signed as shown in
sign_a and sign_b signals provide dynamic control of each operand’s
representation: a logic 1 indicates the operand is a signed number, a logic
0 indicates the operand is an unsigned number. These sign signals affect
all multipliers and adders within a single DSP block and you can register
them to match the data path pipeline. The multipliers are full precision
(that is, 18 bits for the 18-bit multiply, 36-bits for the 36-bit multiply, and
so on) regardless of whether sign_a or sign_b set the operands as
signed or unsigned numbers.
