THE OCULUS-F/64 FRAME GRABBER User's Manual

3.1 INTRODUCTION
The OCULUS-F/64 monochrome frame grabber is a singleor dual slot ISA bus
board. There are three versions available:
• Oculus F/64 Acquisition, processing and display with 8 bit
frame buffer
• Oculus F/64-DSP Acquisition, processing, display with 8 bit frame
buffer and high performance DSP
• Oculus F/64-DSP16 High performance imaging board with DSP and 16
bit frame buffer
The Oculus-F/64 has a flexible acquisition section which provides easy
interfacing to different video sources. The input video format is programmable
and limited only by the amount of memory installed on board and the 40 MHz
maximum sampling rate. The TMS34020 graphic processor provides basic
image processing functionality and also provides acquisition control (up to 40
MegaSamples/sec).
The Oculus-F/64-DSP and F/64-DSP16 are equipped with the TMS320C40
DSP. This provides enhanced acquisition sampling rates, a powerful general
image processing engine, and control for the Oculus-F/64 bus interface.
Real-time IP Engine and histogram processor provide point processing on
incoming or feedback images. Optional 16-bit ( Oculus-F/64-DSP16) point
processing is also available at half the speed when feedback is used (up to 20
MegaSamples/sec with feedback).
There are two types of memory used as frame buffer memory on the
Oculus-F/64, VRAM and DRAM, up to a total of 80 Mbytes. A maximum of
16 Mbytes VRAM memory can be installed. The VRAM memory stores
images that can be viewed via the Oculus-F/64 display system. The remaining
memory is composed of standard 32-bit SIMM DRAM but its contents can not
be viewed directly via the display circuits. A maximum of 32 Mbytes of
DRAM can be installed for the DSP system and another 32 Mbytes of DRAM
can be installed for the GSP. The minimal configuration is 1Mb of frame
buffer memory and 1Mb of GSP memory.
The acquisition and display sections are totally independent. The display
frequencies can be genlocked to a VGA board (VGA pass-through) or
generated on the board. The highest display resolution is 1600-by-1280 at
60Hz. Three separate Look-Up-Tables for VGA, overlay, and video buffer are
provided and can be used simultaneously. The Oculus-F/64-DSP16 also
incorporates a display leveling circuit for displaying any 8 bits from the 16-bit
images.
