1.2 General Description
The miniHiPerCam is one of a growing number of intelligent
cameras from ELTEC. It is a complete CMOS-based color matrix
camera with an intelligent frame grabber together in a small housing.
The miniHiPerCam contains everything that is needed for image
processing. A PowerPC CPU, peripherals optimized for embedded
control applications, fast image and program memory, Flash
EPROM, nonvolatile memory, video output, connectivity via
Ethernet or RS-232, and our proven professional frame grabber
logic.
On-board I/O is intended to communicate with an external computer
through the serial connection or two digital inputs and two digital
outputs. The Ethernet interface can transfer images or image
processing results for remote display or is used for software

download. The on-board video interface drives an analog video
output, supplied for adjustment purposes.
Video input data is stored in main memory (RAM) via an on-board
DMA controller. It can store video data at video rates in several
formats.
Video line pitch is the same as video line length to conserve memory
- lines are tightly packed.
1.3 Mechanical Specification
The miniHiPerCam case has a small cross-section of 43,5 mm x 60
mm and a length of 96,5 mm, making it possible to stack several
HiPerCams in space-constrained applications. The camera has a C-
mount thread for lenses; all electrical connections are routed to the
miniHiPerCam's back panel.
1.3.1 I/O
The PowerPC 823 handles all I/Os: serial, parallel (internal only for
OS debug), real-time clock (without battery-backup), video output,
and Ethernet.

Table 1—3: CPU
The MPC823 is a 32-bit RISC embedded controller with a specific
implementation of the PowerPC architecture. The MPC823 consists
of a highly pipelined processor core and several peripheral interface
units as DMA controller, serial interface, asynchronous interrupt
controller and programmable interval and watchdog timers.
1.4.2 Power Supply
The power supply for the miniHiPerCam must deliver 8V to 24V
with a minimum output power of 5W. The plug must have a
diameter of 5.0mm to 5.5mm and a hole for a 2.1mm pin .
To avoid shortcuts it is strongly recommended that the
power supply has no internal connection to ground.
The miniHiPerCam uses a rectifier for automatic polarity
detection. For compatibility with older versions of the
miniHiPerCam it is recommended to use the inner contact of the
plug for the negative pole.
1.4.3 Video Output
The video output of the miniHiPerCam is 640x480 with 60Hz
refresh rate. It can display 256 out of 4096 colors. The video timing
is rather close to the VGA standard so that it can be displayed with
all VGA monitors. The video interface has a 256x12bit LUT. The 6
least significant bits of the LUT are connected to the 6 least
significant bits of the three DACs. The 2 most significant bits of the
LUT are connected to the 2 MSBs of the blue DAC, the next 2 bits
of the LUT with the 2 MSBs of the green DAC, and the next 2 with

1.4.5 Memory / File system
The miniHiPerCam main memory consists of dynamic memory for
programs, data and images. A boot EPROM contains the complete
operating system Windows CE.
Memory Size
Boot Flash PROM 8 MB Flash (16-bit)
RAM 16 MB 3.3V SDRAM, 32-bit.
Table 1—7: Main Memory
1.4.6 DRAM
The main memory of the miniHiPerCam has a size of 16 Mbytes
consisting of two 64 Mbit SDRAM chips. The memory timing is
5,1,1,1+1 for read and 3,1,1,1 for write bursts. This results in a
bandwidth of 88 Mbytes/s for read and 133 Mbytes/s for write.

User's Manual Specification
miniHiPerCam
1—9
Specification
1.4.7 Flash EPROM
There are 8 Mbytes Flash EPROM installed on the miniHiPerCam. It
holds the basic firmware for system initialization, booting, and
configuration. After reset the Flash EPROM is mapped to
$0000.0000.
Since the Flash EPROM is only 16 bit wide, one burst read of the
CPU lasts about 1.6 us. I.e. the CPU bus is blocked for 1.6 us for
every burst read. It is strongly recommended not to execute code out
of the EPROM when the acquisition and the video output are
enabled.
1.4.8 Video Capturing Modes
Two capturing modes are supported by the miniHiPerCam.
1.4.8.1 Snap:
The next frame is stored in the memory at one of two selectable
addresses.
1.4.8.2 Live:
The next frames are stored in the memory at one of two selectable
addresses until acquisition is stopped.
1.4.9 Lens Adjustment
To adjust iris and focus of the lens it is recommended to connect a
VGA monitor to the video output of the miniHiPerCam and to
enable live acquisition in Y only mode. This results in a live b/w
picture on the video output.

1.4.10 Address Map
The CPU has programmable address decoders for all devices of the
miniHiPerCam. Therefore the addressmap completely depends on
the operating system used.
1.4.11 COM1 Serial Port
The SCC3 of the MPC823 is used as universal serial port (COM1)
that can be programed via standard Windows CE functions. Standard
DB9 serial cables can be attached to the miniHiPerCam via V-
