Product Description

The Adder/Subtracter IP provides LUT and single DSP 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 DSP slice or LUTs. The module can be pipelined.

Key Features and Benefits

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 DSP slice implementations with inputs up to 58 bit
Optional carry input and output.
Optional clock enable and synchronous clear
Optional bypass (load) capability
Option to set the B Value to a constant
Optional pipelined operation
For use with AMD Vivado™ IP Catalog, AccelDSP™ Synthesis Tool, System Generator, and Vitis™ Model Composer
