This unique solution features Altera＇s low－cost Cyclone® III or Cyclone IV FPGAs and intellectual property from Eyelytics and Apical supporting AltaSens＇ 1080p60 A3372E3－4T and Aptina＇s 720p60 MT9M033 HD Wide Dynamic Range (WDR) CMOS image sensors. The all－in－one solution offers surveillance equipment manufacturers the ability to reduce board space, lower power consumption, increase flexibility and reduce development time compared to previous architectures using traditional digital signal processors and ASSPs.
Traditional digital signal processors and ASSPs don＇t have the processing power required to accept the large bandwidth of data from 1080p and 720p WDR CMOS sensors (for instance, a full HD raster is 2200x1125 pixels x 16+ bits per pixel x 60 frames per second, resulting in >2 Gbps bandwidth). Altera＇s Cyclone series FPGAs deliver the bandwidth and processing performance needed, handling large amounts of data generated by today＇s HD WDR CMOS image sensors. In previous designs, HD WDR camera systems required FPGAs to perform the “front end” data processing while a digital signal processor or an ASSP handled the “back end” video encoding. Now, all of these chips can be replaced by a single Altera® FPGA.
The functions of Altera＇s HD surveillance IP camera reference design include：
Apical＇s ISP incorporating best－in－class WDR processing “iridix” together with advanced temporal and spatial noise reduction Apical＇s “checkerboard demosaic” core for the Altasens A3372E3－4T WDR mode “3A” functions, such as auto exposure and auto white balance implemented in software on Altera＇s Nios® II embedded soft core processor Eyelytics＇ H.264 video encoder, capable of 720－line progressive 30 frames－per－second encoding or 1080－line progressive 15 frames－per－second encoding in main profile Altera＇s triple－speed Ethernet MAC intellectual property core
