IGLOO低功耗闪存FPGA系列：
The IGLOO video demo kit, developed and offered by Actels solution partner Attodyne, consists of an IGLOO video demo board and your choice of a LCD adapter board. You can choose from a series of plug-and-play display adapter boards mounted with different LCDs, ranging from 2.7 to 7 and resolution from QVGA (320x240) to SVGA (800x480). The video demo board has an IGLOO device that interfaces with several video/image sources, including DVI input and CMOS Sensor. In addition, off-chip memory is provided for data buffer and storage. The kit is initially available with an LCD adapter board containing 7 LCD panel from Toshiba, and is followed by more adapter boards with panels from other manufacturers. Please refer to the users guide for more details or contact Attodyne.
The IGLOO Video Demo Kit is a versatile development platform that demonstrates various video functions on an Actel IGLOO FPGA. The
video demo kit can be used to evaluate different video reference designs
for both video performance and power consumption. It can shorten
product development cycles by leveraging the board’s spectrum of
possible applications.
