We are developing a database filter which provides selection and
projection in hardware. In other words, the hardware will
execute an SQL statement like
"Select A,B,C from FILE
where ((D = 'red' and (E < 10 or E > 6)) or A < B)"
The internal speed of the filter is about 10 Megabytes per Second.
The driver on which the filter is being prototyped is an
onboard 68010 for initial setup plus a DMA 68450 for running
the data through. The DMA 68450 uses 1 channel for the host computer,
1 channel for an onboard SCSI port, and 2 channels for the filter.
Board interface to the VME is being worked on although
IBMPC and IBMAT backplane interfaces could easily be built.
Is there any interest in this product? Are there any
similar products already on the market? What sort of prices
do these types of products sell for? I would appreciate any comments
on what we are trying to do.
Our reason for asking you is that our financial sponser (National
Research Council of Canada) is asking us about potential market
of the product.
