Matrox Rapixo CL Pro, Installation And Hardware Reference, Page: 12 / 96

12 Chapter 1: Introduction
• Auxiliary, multi-purpose signals. These are non-video signals that can support
one or more functionalities (for example, trigger input, rotary/linear encoder
input, or timer output), depending on the auxiliary signal.
• Integrated quadrature decoders. These can decode input received from a rotary
or linear encoder with quadrature output.
• Programmable lookup tables (LUTs). These allow Matrox Rapixo CL Pro to map
data to precalculated values, before it is stored in memory.
• Matrox Rapixo CL Pro can provide 4.8 W of power per Camera Link connector
to any device that supports power-over Camera Link (PoCL). This means that it
can provide 4.8 W to a Base camera, or 9.6 W to a Medium or Full camera.
On-board memory
Matrox Rapixo CL Pro is equipped with 4 Gbytes of DDR3 SDRAM on-board
memory. This memory is accessed through the memory interface, and is used to
store acquired images. The memory controller has multiple input ports, and it has
a maximum data transfer rate of 14.4 Gbytes/sec.
Data transfer
Your Matrox Rapixo CL Pro can send data to the Host at a maximum theoretical
transfer rate of 4.0 Gbytes/sec. Optimum conditions for high speed transfer
include using the board in a PCIe 2.x slot with 8 active lanes, using a 256-byte
payload. DMA write performance is chipset and computer dependent, and is
slightly affected by the image size and alignment in Host memory (frame start
address and line pitch).
To measure the effective available bandwidth of the PCIe slot in your computer
with your Matrox Rapixo CL Pro board, Matrox provides the Rapixo CL Bench
tool. These tools are integrated in the MILConfig utility, which is shipped with
software that supports Matrox Rapixo CL Pro (for example, MIL).
Documentation conventions
This manual refers to all Matrox Rapixo CL Pro boards as Matrox Rapixo CL Pro.
When necessary, this manual distinguishes between the boards using their full
names. Also note that, when the term Host is used in this manual, it refers to the
host computer.
