Cast LogoJPEG compression IP core supports baseline sequential DCT and extended sequential DCT modes of the ISO/IEC 10918-1 standard.

An area-efficient, high-performance JPEG encoder core for FPGAs with very low processing latency.

JPEG-EX-S encoder produces compressed JPEG images and video for Motion JPEG container formats from images with up to 12-bit color samples and four color components.

  • Single-frame JPEG images and Motion JPEG payloads for any image size up to 64K x 64K with programmable Huffman and quantization tables
  • Multiple interface support like AXI streaming pixel compressed stream interfaces and APB control/status interface
  • Rate control options that limit the size of each individual frame for images and regulates bit rate over a number of frames for videos
  • Easy to integrate automatic program-once/encode-many operation and simple, dedicated timestamps interface
  • Bit-accurate software model generates test vectors, expected results, and core programming values
