11.1. Features
The ALTMULT_ADD IP core offers the following features:
- Generates a multiplier to perform multiplication operations of two complex numbers
- Supports data widths of 1– 256 bits
- Supports signed and unsigned data representation format
- Supports pipelining with configurable output latency
- Provides a choice of implementation in dedicated DSP block circuitry or logic elements (LEs)
Note: When building multipliers larger than the natively supported size there may/will be a performance impact resulting from the cascading of the DSP blocks.
- Provides an option to dynamically switch between signed and unsigned data support
- Provides an option to dynamically switch between add and subtract operation
- Provides an option to set up data shifting register chains
- Supports hardware saturation and rounding (for selected device families only)
- Supports optional asynchronous clear and clock enable input ports
