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
