Adder/Subtracter
Overview
The Adder/Subtracter IP provides LUT and single DSP48 slice add/sub implementations. The Adder/Subtracter module can implement adders (A+B), subtracters (A–B), and dynamically configurable adder/subtracters which operate on signed or unsigned data. The function can be implemented in a single DSP48 slice or LUTs. The module can be pipelined.
Key Features
- Generates adder, subtracter and add/subtracter functions
- Supports two’s complement-signed and unsigned operations
- Supports fabric implementation inputs ranging from 1 to 256 bits wide
- Supports DSP48 slice implementation with inputs up to 48 bits wide
- Optional carry input and output.
- Optional clock enable and synchronous clear
- Optional bypass (loud) capability
- Option to set the B Value to a constant
- Optional pipelined operation
- For use with Xilinx Vivado® IP Catalog, Xilinx AccelDSP™ Synthesis Tool, and Xilinx System Generator.
