Cyclone III FPGAs in Display Applications

Cyclone^® III FPGAs deliver an unprecedented combination of low-power, high functionality, and low cost. The Cyclone III family’s memory-rich architecture, embedded multipliers, integrated differential I/O, and enhanced phase-locked loops (PLLs) give you the flexibility to create a single platform for multiple product lines and image resolutions.

Take a look at some of the most significant Cyclone III FPGA display application advantages:

Feature	Advantage
*Table 1. Key Display Application Advantages of Cyclone III FPGAs*
Abundant Memory and Multipliers	Efficient frame buffering Optimized for HD line buffers
Flexible Column Driver Interface Support	Integrated differential buffers, including LVDS, mini-LVDS, reduced swing differential signaling (RSDS) and point-to-point differential signaling (PPDS) Reduced I/O design effort and external components
Video and Image Processing (VIP) Suite	A suite of nine pre-optimized video and image intellectual property (IP) cores, including deinterlacer, scaler, and filters reduce time and effort to increase productivity
Flexible PLLs	Dynamic reconfigurable phase and frequency shifts to support multiple refresh rates Up to 5 outputs per PLL to minimize number of PLLs required for display applications PLL cascading to increase flexibility of multiplication and division factors Supports low cost 5-MHz to high performance 440-MHz clock input frequencies
Low Power	Extends battery life for portable display applications

Typical LCD TV interface

The heart of the LCD HDTV is its image-processing and timing-control block. The image-processing block typically includes functions such as scan rate converter, frame rate converter, color decoder, motion detection, scalar, and deinterlacing. Cyclone III FPGAs offer a wide range of densities to support any display, from small or low-resolution displays all the way up to large or higher resolution displays.
