Features

The LPM_MULT megafunction offers the following features:
• Generates a multiplier that multiplies two input data values

• Supports data width of 1–256 bits

• Supports signed and unsigned data representation format

• Supports area or speed optimization

• Supports pipelining with configurable output latency

• Provides an option for implementation in dedicated digital signal processing (DSP) block circuitry or

logic elements (LEs)
Note: When building multipliers larger than the natively supported size there may/will be a perform‐

ance impact resulting from the cascading of the DSP blocks.

• Supports optional asynchronous clear and clock enable input ports
