The folks at Xilinx say that their Virtex-4 SX field programmable gate array (FPGA) chipsets have been approved for Dolby Laboratories' recent high dynamic range (HDR) innovations. Dolby joins a growing number of industry leaders leveraging the Xilinx high-performance XtremeDSP solutions to introduce innovative technologies.
Display technology preferences vary across geographies and end markets. By combining the flexibility of a programmable architecture with high-performance DSP capabilities, high-definition display developers can create tailored solutions based on the specific needs of each end customer or partner. At speeds of 500 MHz, Xilinx Virtex-4 SX DSP slices are claimed to deliver an aggregate DSP bandwidth of 256 GigaMACs/second, while consuming a mere 57 µW/MHz.
Dolby's LED-backlit LCD display technology
Dolby's HDR technologies provide improved contrast ratio and image quality by leveraging light-emitting diodes (LEDs) with local dimming. In addition it adds advanced high dynamic range capabilities to LED-backlit units, increasing both the brightness and contrast of an LCD display. Dolby HDR technologies offer a picture quality that virtually matches real-world perception of depth, detail and color, surpassing the picture quality of conventional LCD displays.
