FEATURES
OVERVIEW
The picassoTM PCI-2SQ is a high-performance ‘plug and play’ PC-card for the PCI-bus. It
enables each standard PCI system to capture and store single images for image processing or
full-frame display of real-time video in a window maximum (30 frames/sec).
The picassoTM PCI-2SQ operates as a PCI bus master, allowing it to transfer images directly to
the system memory or the VGA memory without impacting the processor. The picassoTM PCI-
2SQ has four composite video inputs or two S-video inputs that are software controlled and
accept NTSC, PAL or SECAM video signals.

FEATURES
FEATURES
n32-bit PCI interface
The picassoTM is a full PCI 2.1 bus master with a transfer rate up to 132
Mbytes/sec. This allows the bus master to transfer up to 30 frames/sec. Support
of zero wait state burst transfers.
nMultiple colour/monochrome video inputs
Several configurations are possible, they are software controlled. Maximum of 4
CVBS or 2 S-video inputs.
nResolution
24 bit colour levels. Square pixel format with a maximum of 768/640 active
pixel resolution per frame. Automatic selection of NTSC, PAL, SECAM.
nAutomatic detection of 50/60 Hz
nRS-170 CCIR 601 level-compatible
nSquare pixel – 1:1 aspect ratio
nAutomatic or programmable gain control
nReal-time scaling
Useful for reducing the size of images on the display. Images can be scaled down
randomly.
nMemory
Memory Management Unit (MMU) supports Virtual Memory up to 4
Mbytes/DMA channel. The picassoTM has 3 DMA channels.
nData Formats
Data can be stored in several RGB formats in system memory or the displays
adapter frame buffer.
nTwo digital inputs and two digital outputs
The picassoTM has two optical isolated digital inputs and outputs. They are
software controlled and they can be used for external events such as light
switching and camera triggering. The inputs can be programmed as interrupt for
fast input reaction time.

GETTING STARTED
1. GETTING STARTED
1.1 Hardware and Software Requirements
The following minimum system characteristics are required by thepicassoTM .
nIBM PC or PC compatible Pentium 266MHz (or higher performance system).
nOne available PCI version 2.1 bus master expansion slot (32-bits and 5 V I/O).
n32 Mbytes of RAM.
nPCI compliant VGA or Super VGA board, with 2 Mbytes linear accessible frame buffer
(supporting one or more of the colour space formats supported by thepicassoTM ).
nA mouse or compatible pointing device.
nOne 3.5 inches floppy disk drive for installation.
ARVOO recommends systems with newer PCI-chipsets, such as Intel 440BX, i810 or i820.
1.2 Installing the picassoTM
1. Select a 32-bit PCI bus master expansion slot. Refer to your computer systems user manual to
determine which slots are bus masters.
2. Remove the metal bracket.
3. Before handling the board, discharge any static build up on your body by touching the metal
case of the computer. Remove the board from its bag and hold the picassoTM by its top edges
and do not touch its components.
4. When the bottom of the board contacts the bus connector, gently press down on the board
until it is fully seated. Secure the board using the removed screw from the slot cover.
5. Connection of the video signal to the picassoTM is accomplished using a standard S-video
connector (4 pins minidin). One way of connecting the video signal is using the cable
delivered with the picassoTM. This cable converts the S-video to 2x cinch (phono male
connectors) or 2x BNC.

1.3 I/O connectors
1.3.1 Video sources
The picassoTM supports up to four video sources. The video input-connectors VID0 and VID1
are 4-pins minidin female connectors [see Figure 2].
nComposite video sources (CVBS) are connected to input A-D of VID0 and VID1
[see Table 1].
nS-video (S-VHS or Hi8) is connected to VID0 and VID1. Inputs A and C are used for the Y
(luminance) channel of the S-video source. Inputs B and D are used for the C (chrominance)
channel of the S-video source [see Table 2].

GETTING STARTED
Example to connect four composite video signals to the picassoTM:
Table 2 shows the connection of two S-video sources to the picassoTM. A connection example is
given in Figure 4.
The selection of the different Video inputs is software controlled. You can select one mode at
one time.
ATTENTION: When you use the delivered cable with the frame grabber then the RED cinch-
plug (phono connector) is connected to pin 3 of the VID 0/1 minidin and the
BLACK cinch-plug is connected to pin 4.

1.3.2 General Purpose Input /Output connector
The General Purpose Inputs and Outputs are connected to the picassoTM by a sub D-9 connector.
In Figure 5 you see a close-up of the sub D-9 connector. The pin connections are listed in
Table 3.
When you use the general-purpose inputs or outputs you have to connect an external 5 V power
supply. The maximum voltage is 5.5 V and the input current is 10 mA.
ATTENTION: The maximum output current is 100mA.
The outputs are open drain, which means that logic 1 will force the output to ground. A wiring
example to connect an output is given below.
ATTENTION: When the computer is turned off and the external power supply stays up the
output will also be forced to ground.

OPERATION PRINCIPLES
2. OPERATION PRINCIPLES
2.1 Functional Overview
Front-end
The Front-end accepts either single composite video or separate Y and C signals. Channel
selection is handled through a video mux which is software controlled.
The Front-end is compatible with PAL B/G, NTSC M and SECAM.
PCI-bridge
The images can be scaled down randomly. By specifying starting pixel, line locations and size an
exact region can be selected. The user has to specify both the source and target fields.
The scaler controls also brightness, contrast, hue and saturation. The data can be stored in
different RGB output formats.

OPERATION PRINCIPLES
I/O controller
The input register is read-only and must be driven by an external source. It is possible to
generate interrupts from the inputs. The output register is read-write.
PCI-interface
The scaled image is transferred directly to the system memory or the displays frame buffer under
program control.
