The UHT-DSC-D core from Alma Technologies is an advanced decoder, compliant to the VESA Display Stream Compression (DSC) v1.2b standard.
It supports decoding of 4:4:4, 4:2:2 and 4:2:0 video streams with 8 to 16 bits per component color depth.
The core is scalable and has been designed for enabling ultra-high throughput video decoding, even in medium-range target implementation technologies.
It is available for ASIC or Altera, AMD-Xilinx, Efinix, Lattice and Microchip FPGA and SoC based designs.
The UHT-DSC-D is designed using internal (on-chip) memory blocks only, with simple and fully controllable streaming input and output interfaces. It is a complete and autonomous decoder, not needing any host system CPU or GPU support for its operation. Being carefully designed and rigorously verified, the UHT-DSC-D is a reliable and easy-to-use and integrate IP core.
