Auto Contrast Enhancement (ACE) IP Core

Request Information

Product Description

The Auto Contrast Enhancement (ACE) IP core produces the low-contrast enhanced output stream by histogram analysis of the input stream without loss of image details. The IP follows AXI4 protocol allowing easy IP integration with the user’s design. IP core has AXI4 interface ports for stream, memory and control.

Key Features and Benefits

  • Generates contrast-enhanced output
  • Configurable parameters such as resolution, gray level, enhance mode( 0 - original unenhanced output, 1 - contrast-enhanced output)
  • Supports a maximum of 1920x1080, resolution with 1 pixel per clock
  • Supports 24-bit RGB input and output
  • AXI4-Lite control interface
  • AXI4-Stream interface for input and output video
  • AXI4-MM interface for reading stream data from memory
