10xEngineers Polyphase Video Scaler is a high performance, high quality, video scaler IP core capable of scaling up or down the input video stream by any factor. The IP supports scaling from an arbitrary input resolution to a wide range of output resolutions for video and graphics applications. It is provided as a highly optimized, synthesizable soft IP core for AMD® Xilinx® Ultrascale+™ FPGA devices. While optimized for Xilinx® FPGAs, the IP core features an FPGA agnostic design that can be easily ported to other FPGA devices.

Our polyphase scaling algorithm is engineered for applications that demand premium image quality and broadcast-level performance. Compared to basic methods like nearest-neighbor or bilinear interpolation, the polyphase approach uses advanced multi-tap interpolation filters designed to deliver superior visual fidelity across all resolutions.

This technology provides a sharper, more detailed output with minimal aliasing and edge blurring, making it ideal for high-end video processors, AI upscaling engines, and professional display systems. By using larger interpolation filters than the standard 2×2 bilinear filter, the algorithm achieves an improved frequency response, resulting in crisper visuals and smoother gradients during both upscaling and downscaling operations.
