General Description and Architecture General Description
Version C.1 BitFlow, Inc. CXP-1-9
1.2.11 The Timing Sequencer Signal Generator
With the release of the Cyton-CXP, BitFlow introduced a new signal generator, the
Timing Sequencer. The Timing Sequencer (TS) is more flexible and more power than
the timing generators used on early BitFlow frame grabbers. It has the ability to out-
put multiple different size pulses, each of which can free-run or require a trigger. The
TS is more accurate than the NTG and has a finer granularity. The TS can also be
changed on the fly, with switch overs to the new timing exactly synchronized. See sec-
tion 4.1 for more information.
The Aon and Claxon provides the same TS as the Cyton.
1.2.12 The StreamSync System
The Cyton-CXP has a brand new, designed from scratch acquisition and DMA engine
called the StreamSync system. The StreamSync system has been designed to opti-
mize acquisition and DMA throughput over the PCIe bus given a wider variety of
internal PC conditions. In addition, the Stream Sync system has been designed to
automatically resync and recover should there every be packet lost (either on the
input or the output side of the board), resulting in much more usable and fault toler-
ant image sequences in host memory. For more information see Section 2.1 and Sec-
tion 3.1.
The Aon and Claxon use the same StreamSync Acquisition engine as the Cyton.
1.2.13 The Volume Of Interest Acquisition Engine
The Cyton-CXP introduces the concept of Volume of Interest (VOI) as part of its
StreamSync Acquisition Engine. This has been designed from the ground up to satisfy
the needs of real world machine vision application. The VOI provide robust and flexi-
ble programming that can handle of a wide variety of pixel, line, frame and sequence
acquisition commands either manually from software control, or externally via hard-
ware triggers. There is fully support for X and Y offsets, X and Y Region of interests,
sequences and sequences of sequences. See section 2.2 for more information.
The Aon and Claxon also use the VOI Acquisition Engine.
1.2.14 CoaXPress Power
The CoaXPress specification specifies that the frame grabber must be cable of supply-
ing up to 13 W at 24V on each CXP link. The Aon/Claxon/Cyton conforms to this spec-
ification. Some cameras do not require power, so the Aon/Claxon/Cyton can
optionally turn power on or off via its registers. Normally this information is part of the
camera configuration file, thus files for cameras that require power are so indicated.
The Aon/Claxon/Cyton automatically powers up all links that need power (i.e. cor-
rectly respond to the sense circuit). This happens as soon as the system is booted.
