Expanding its FPGA solutions for the surveillance market, Altera (
News -
Alert) Corp. (
www.altera.com) has unwrapped industry's first high-definition (HD), intellectual property (IP)
reference design for surveillance cameras on a single
FPGA.
This unique solution features Altera's low-cost
Cyclone III or
Cyclone IV FPGAs and IPs from Eyelytics (
www.eyelytics.com) and Apical Ltd. (
www.aplical-imaging.com) 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 (DSPs) and application-specific standard products (ASSPs), claims Altera's release.
According to Altera, traditional DSPs 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, as shown in the release. However, Altera says that its
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 DSP or an ASSP handled the 'back end' video encoding. Now, all of these chips can be replaced by a single Altera® FPGA, asserts the maker.
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 IP core
The bundling of a comprehensive list of IPs in this reference design gives designers a head start in camera development, shortening development time by as much as one year. All camera designers have to do is customize the FPGA with their own specific features, such as adding their own software for motion detection, and pan, tilt and zoom control, as per the FPGA supplier's release.
Altera's director of the industrial and automotive business unit, Michael Samuelian stated, 'Altera is taking surveillance another step further by delivering a complete single-chip solution that not only addresses the trends from standard definition to high definition, standard CMOS sensors to WDR CMOS sensors, but makes it more cost effective for surveillance-camera designers to produce high-resolution images over an internet protocol network.'
