The CXC-1 is a parameterized integration of the VPC-1 Deinterlacer and VSC-1 Scaler IP cores along with all circuitry necessary to interface to a DRAM controller. The CXC-1 greatly simplifies using the VPC-1 and VSC-1 in a wide range of applications. All build-time parameters supported by the VPC-1 and VSC-1 are available at the top level of the CXC-1. Additional build-time parameters are provided to include or exclude certain processing blocks. This allows, for example, the CXC-1 to be configured as a full up/down/cross converter or as a deinterlacer only or a scaler only.


  • Parameterized integration of VPC-1 deinterlacer and VSC-1 scaler IP cores with flexibility to address wide range of applications
  • Dynamic resizing and real time aspect ratio conversion (ARC) without artifacts
  • Region-of-interest (ROI) scaling
  • 8/10/12-bit 4:2:2 or 4:4:4 processing
  • Includes all circuitry required to interface seamlessly with Intel® FPGA memory controllers

Device Utilization and Performance

16.5K ALMs, 885K bits, 45 DSPs (Cyclone V)Fmax = 150 MHz

Getting Started

Evaluation can be performed using pre-built bitstreams for standard Intel® FPGA dev kits or a time-limited trial of the actual IP
