The VM-A005 Imaging
Development Kit (IDK) is designed to be the basis of imaging engineering
and prototyping. The core of the system is an Altera Cyclone III FPGA,
and a powerful set of tools that enable
image sensor capture and USB 2.0 HS interface to a PC. The kit is
further enhanced with a PC application and matching embedded drivers to
capture
video
and still images, and then perform color processing and analysis.
Users of the IDK will find
that it is very versatile, with the ability to
create PC or embedded new functions. It comes with source code and
examples to get a user started, and can be used for image capture right
out of the box. All developmental functions are enabled right over the
single PC and USB connection from new function coding, compiling,
downloading of firmware, testing & debug, and user functionality.
The IDK comes with a
modular image head design, which can be modified and changed by the user
or VisionMOS engineering to meet specific needs. Options include the
image sensor itself as well as the optic type and filtering. A common
interface between the image head and the board allow for quick interchange
of various sensors and functions.
The main board of the
system has an integrated USB 2.0 microcontroller, which handles both
bi-directional communication and high speed bulk data handling. A user
manual included in the kit allows the user to understand and interact with
various USB commands for control of the system.
This kit can be used for the following applications:
-
Rapid Prototyping and
Development of Altera Cyclone Design
-
Digital Camera/Image Sensor

The Cyclone III FPGA is the
heart of this Development Kit. It offers an unprecedented combination of low
cost, higher density and low power consumption. The FPGA contains an optimal
set of features used to drive high-bandwidth parallel processing. The highly
integrated FPGA consists of 10K Logic Elements, 400K bits of embedded memory
and multiple hardware accelerators. The Development Kit consists of
preprogrammed hardware elements, the VM VisionPro PC application with
Graphical User Interface (GUI), Windows drivers and custom Dynamic Link
Library (DLL). The application, VM VisionPro, includes an Image
Analysis/Processing package and Image capture interface. An FPGA Programmer
and an Integrated Circuit Communications Compliant1 (I²C) Communications
interface will aid in development of custom designs. VM VisionPro enables
communications to all hardware elements and GPIO timing controls. Extensive
documentation included with the kit ensures a complete understanding of the
system operation.
The Development Kit offers the
ability to design, compile, download and execute, all via the USB port on
your PC. The use of non-volatile memory eliminates the need of constant
reprogramming. Free tools including the custom VHDL source code (supplied)
with the kit along with free industry standard tools available online allow
for a wide range of design flexibility without the need or expense of
additional components. This kit can be used to support development from
image processing algorithms to automatic camera control.
