The Display Stream Compression (DSC) standard from the Video Electronics Standards Association (VESA) offers visually lossless compression for high definition (HD) video in broadcast, automotive, medical and consumer electronics applications. The Trilinear Technologies M25 DSC 1.2 Decoder offers real time decompression of HD streams with resolutions from 480p up to 8K. The decoder core is fully compliant with the VESA DSC 1.2 standard and is available for both FPGA and ASIC platforms.

The M25 core is delivered with an industry standard AMBA 3.0 Peripheral Bus interface for host configuration and decoder control. The encoded input interface is AXI4-Stream Protocol compliant and the output interface uses a streaming data structure with associated line and frame formatting signals. The DSC 1.2 Decoder core supports 8, 10, 12, 14 or 16 bits per pixel using either the RGB or YCbCr in 4:4:4 or 4:2:2 format.

The M25 DSC 1.2 Decoder core ships with a complete ‘C’ reference driver and a fully documented API. The core is available on the Trilinear Technologies’ Cobra Development platform based on the Xilinx Kintex-7 FPGA family. This FPGA based reference system provides a complete development environment for core evaluation as well as early software development.

Availability and Pricing

The Trilinear M25 DSC 1.2 Decoder and M27 DSC 1.2 Encoder are currently in production.  The cores are available as a standalone product or as an additional feature of the widely-adopted Trilinear Technologies DisplayPort 1.4 Transmitter and Receiver cores.  The cores are shipped with a complete reference driver as well as application layer sample code.

About the Display Stream Compression Standard

VESA, the Video Electronics Standards Association, has published a new Standard in 2014 that uses visually lossless image compression to increase the amount of data carried by a display interface data rate, saving power.  DSC achieves visually lossless compression quality at a low compression ratio by using a much simpler codec (coder/decoder) circuit. The typical compression ratio of DSC range from 1:1 to about 3:1 which offers significant benefit in interface data rate reduction.  The current version of the standard is DSC 1.2 and was approved January 20, 2016.
