XCKU095-2FFVB2104E Logic Resources in Detail
CLB and LUT Architecture
The XCKU095 uses the UltraScale configurable logic block (CLB) architecture, which is based on 6-input LUTs (LUT6). Each CLB contains eight 6-input LUTs and sixteen flip-flops. With 537,600 LUTs and 537,600 flip-flops, the XCKU095-2FFVB2104E supports highly complex, resource-intensive designs such as packet processing pipelines, video processing engines, and large state machine implementations.
DSP Resources
The device includes 4,100 DSP48E2 slices, each capable of executing a 27×18 multiply-accumulate (MACC) operation per clock cycle. At 725 MHz (-2 speed grade), this translates to exceptionally high signal processing throughput, making the XCKU095-2FFVB2104E a top choice for applications such as:
- Software-defined radio (SDR) and 5G baseband processing
- Medical imaging reconstruction (CT, MRI, ultrasound)
- 8K/4K video processing and codec acceleration
- Radar and LIDAR signal processing
Block RAM
The XCKU095-2FFVB2104E provides approximately 59 Mb of on-chip Block RAM, arranged in 36Kb true dual-port tiles. This large on-chip memory pool enables efficient buffering, data caching, and lookup table storage without requiring costly off-chip memory accesses for latency-sensitive operations.
