General acquisition features
Matrox Radient eCL supports frame and line-scan monochrome and color video
sources. The color video sources can be RGB video sources or video sources with
a Bayer color filter. Matrox Radient eCL can decode Bayer color-encoded images
on-board if the selected Processing FPGA configuration supports Bayer color
decoding and the decoding supports the image size and depth; the standard FPGA
configuration supports Bayer color decoding. Besides standard Camera Link video
sources, Matrox Radient eCL also supports additional types of video sources,
including some time-multiplexed video sources and 10-tap 8-bit video sources.
Processing capabilities
Matrox Radient eCL features an on-board real-time processing FPGA device,
which can be configured to offload and even accelerate the most
compute-intensive part of typical image processing applications, without
generating additional data traffic within the host computer (Host).
Processing FPGA
The Processing FPGA on Matrox Radient eCL is a highly customizable, Altera
Stratix III or IV FPGA, with a core clock of up to 133 MHz. The operations
performed on-board are controlled using the Matrox Imaging Library (MIL)
application development software. Using MIL, the processing units (PUs) of an
FPGA configuration can be rearranged to perform the operations in the required
sequence, without having to necessarily generate a new FPGA configuration.
When the need arises, Matrox’s FPGA design services can be employed to generate
an application-specific FPGA configuration.
Before the Processing FPGA can process grabbed images, they must be stored in
main on-board memory. If images stored in Host memory are required, they can
be streamed directly to the Processing FPGA for processing. Images resulting from
Processing FPGA processing can be stored in main on-board memory or streamed
to the Host.
On-board acquisition and processing memory
Matrox Radient eCL has two types of on-board memory: main on-board memory
and dedicated Processing FPGA memory (optional).
Main on-board memory is used to store acquired images, and images for or
resulting from processing. As main on-board memory, Matrox Radient eCL is
equipped with 2 Gbytes of DDR2-667 SDRAM. Main on-board memory is
accessed through the memory controller of the Processing FPGA. The memory
controller has multiple input ports and a data transfer rate of up to
10.6 Gbytes/sec.
