XCKU085-2FLVB1760I Architecture Overview

## UltraScale Architecture: What Sets It Apart

The XCKU085-2FLVB1760I is built on AMD’s UltraScale architecture, the first ASIC-class programmable architecture to address the needs of next-generation system integration. Key architectural advantages include:

• Advanced Routing Architecture: Eliminates the interconnect bottleneck found in previous 7-series devices, enabling near-ASIC routing efficiency.
• Next-Generation CLBs: Configurable Logic Blocks with 8-input LUTs and enhanced carry logic for faster arithmetic operations.
• Stacked Silicon Interconnect (SSI) Technology: While the XCKU085 uses a monolithic die, the UltraScale family supports SSI for larger devices, enabling seamless scaling.
• UltraRAM (on select variants): High-density on-chip memory blocks that significantly reduce BOM costs in memory-intensive designs.

### DSP48E2 Slices: Signal Processing Powerhouse

With 2,760 DSP48E2 slices, the XCKU085-2FLVB1760I delivers exceptional fixed-point and floating-point signal processing capability. Each DSP48E2 slice supports:

• Pre-adder, multiplier, and accumulator in a single clock cycle
• Cascade connections for implementing large multipliers and filters
• Optional pattern detection for overflow detection and counter auto-reset
• 27×18-bit two’s complement multiplication

This makes the XCKU085-2FLVB1760I ideal for FFTs, FIR filters, matrix computations, and machine learning inference engines.
