XtremeDSP Powers Dolby High Dynamic Range Technology
Dolby Laboratories, Inc. (NYSE: DLB) has approved Xilinx Inc. (Nasdaq: XLNX) Virtex(TM)-4 SX field programmable gate array (FPGA) chipsets for their high dynamic range (HDR) algorithms for LCD televisions with LED backlighting. Dolby selected XtremeDSP solutions because of the inherent ability of FPGAs to implement highly parallel architectures. The result is a performance of up to two orders of magnitude higher than discrete DSP processors.
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 deliver an aggregate DSP bandwidth of 256 GigaMACs/second, while consuming a mere 57 micronW/MHz.
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.
