Features

The JPEG/MJPEG encoder IP core is a single chip solution that supports single image and video encoding for the resolutions including QVGA and VGA up to 30fps.

The encoder IP core is a vendor and device independent, and supports, not limited to, FPGAs of Xilinx, Intel (Altera), and Microsemi. Main features are:

  • Frame format VGA, QVGA.
  • Frame rate 30fps max.
  • JPEG header included.
  • User selectable three of Quantization levels.
  • Chroma Format 4:2:2.
  • Pixel data 8bits.
  • FPGA clock 48MHz max (2 times of pixel clock).
  • External memories not required.
  • Output data rate 3.5Mbyte/sec max (Depends of frame rate and quantization level).

Applications

  • Portable digital cameras.
  • Camera door bells.
  • Video surveillance cameras.
