Near-Lossless Encoder/Decoder

Reduce internal memory and logic gate count

Techno Mathematical Co., Ltd. provides a compression algorithm, powered by the original computing algorithm DMNA, enabling high-speed, compact, and high-quality compression and decompression. This compression algorithm significantly reduces internal memory and logic gate count, supporting lossless or near-lossless modes with programmable compression ratios, automatic control of compressed data size, and compatibility with huge screen sizes.

Features

  • High-Speed Compression & Decompression: Capable of handling 3 pixels/clock for encoding and 2 pixels/clock for decoding (example in ASIC).
  • Flexible Image Size Support: Programmable image size ranges from 768 to 65,280 pixels in width and 6 to 65,532 pixels in height, accommodating various image formats (RGGB/GRBG/GBRG/BGGR Bayer Format).
  • Versatile Compression Modes: Offers both "LossLess" and "NearLossLess" (1/2, 1/3, 1/4) compression modes.
  • Interface Compatibility: Supports AXI 128bit Bus Master and AHB Host access interfaces, ensuring flexible design adaptation as per customer requirements.
  • Cost and Power Optimization: Optimized logic gate count and internal memory capacity, reducing overall cost and power consumption for efficient bandwidth and file size reduction in image processing.
