Introduction

DVP RX Controller is a parallel camera interface controller that supports communicating with Digital Video Port (DVP) protocol. The controller provides 2 AXI interfaces to stream the pixels and configure the controller. The user can configure an internal Direct-memory-access (DMA) to set streaming pixel out mode. Moreover, the controller provides some features: hardware image resizer, pixel-misalignment automatic correction, etc.

Feature

• Support DVP protocol
• Support AXI4 Slave interface to configure the controller
• Support AXI4 Master interface to stream images
• Support configurable DMA to stream images
  • 2D transfer mode
  • Cyclic transfer mode
• Support interrupt outputs for Image capturing and Image streaming
• Support pixel-misalignment automatic correction
• Support a configurable image resizer
  • Image Downscaler (ratio 4:1)
  • Pixel Grayscale (RGB to Gray)
