XC4VSX55-11FFG1148I, Virtex-4 SX55 DSP-focused FPGA designed for high-throughput real-time signal processing.
Compared with FX series (which include embedded CPUs), the SX family is built for pure processing power — more DSP resources, faster data paths, and better performance for math-intensive workloads.
In simple terms:
👉 If your design is heavy on FFT, filtering, modulation, or real-time data streams, this is the right Virtex-4 device.
