MaxVideo 250 Datacube Image Acquisition VME Module

Datacube's MaxVideo 250 provides image acquisition, storage, processing, and display functions on a single, one-slot VME card that is more powerful and versatile than any other VME product available. With 7,000 MIPS of processing power, it supports multiple, simultaneous pipelines, switchable by software at frame rates. It derives its power from pipeline processing -- a method of specialized parallel processing uniquely suited to the demands of image manipulation. Fast VMEbus transfer is available for applications where access to image data by the host CPU is useful.

Each board has six VSIMs (Virtual Surface Image Memories) that provide a total of 28 MB of memory. In addition to being surface stores, VSIMs have a crosspoint switch, statistical processor, LUT, and ALU, allowing them to perform specific processing functions at 40 MHz.

The MaxVideo 250's massive crosspoint switch provides 640 MB/second of internal bandwidth. Linear, non-linear, convolution, histogram, and statistical processing operations can be performed simultaneously at frame rates by connecting the processing elements under the control of ImageFlow software.

High Speed Image Access (HSIA) enhances the transfer of frame-rate image data over the VMEbus. In some applications, HSIA allows utilization of the host CPU to augment image processing functionality.

The MAXbus ports allow image data interchange with no performance penalty between the MaxVideo 250 and other boards such as Datacube's XI Display Controller and MD1 Digital Image Recorder. It also allows cascading of multiple MaxVideo 250s for enhanced processing horsepower.
