VHDL is a Hardware Descriptive Language very similar to ANSI C.
http://en.wikipedia.org/wiki/VHDL
http://en.wikipedia.org/wiki/Hardware_description_language
HDLs are used to describe and model hardware systems. The code is just
like any other code. Running the code thru a compiler - logic
synthesiser - produces a circuit diagram and a fusemap. You can use
the circuit diagram and build hardware that will work just like you
described in the HDL code. Or you can use the fuse map to blow /
reconfigure an FPGA to create the circuit or send it to a fabhouse to
create a custom ASIC.
(the above para is a gross simplification but suits us for now)
One can easily patent the resultant ASIC. So by extending the logic
backward one can patent the Parent HDL code. However while patenting
the ASIC one is patenting one single specific implementation of the
circuit. If the HDL code were patented, One could reduce any code
(even highily disimilar code which produces very different physical
hardware, but capable of producing identical end results) to show
that it is similiar to the patented code.
Modern ASICs allow creation of FPGA + ASIC + Microprocessor + RAM
blocks in a device. Add a driver which programs the FPGA and
downloads an API so that it's functionality is exposed for use. Now
patent the whole lot by extending the HDL-patent case a little more.
It is after all a sort of software tied to specific machine limited
hardware which makes a useless piece of silicon do something unique.
Examples of such hardware in widespread use was in the previous mail.
From this point it is very easy to get rid of the hardware requirement
completely and patent the HDL code ( description of specific
hardware) + driver (software with machine limitation which downloads
microcode for execution there bundled with application (more software
with machine limitation). If you wanted to seperate this blob into
HDL, microcode and application you would most likely be contaminated.
Now just build your PC with gizmos in the previous mail examples and
you have a completely un reverse engineerable combo of what? - non
generic hardware?, software?, driver?. Since the API now exists
within the patented blob reverse engineering will screw you up,
unless you have an army of lawyers.
In short "specific hardware" is extremely generic until the software
gets in whence it morphs into "special adoption or modification of
its hardware or organization ".
In the above i have restricted myself to silicon. But the same could
apply to full machines - robots -. What a robot does is totally
dependent on the software. You could make it do flips or eye surgery.
What you should aim at is complete ban on patents for any software /
process / method irrespective of it being tied to specific hardware,
including the results of code being morphed into machine readable
binaries, either for execution on, or modification of internal
elements in FPGA / ASIC / General or special purpose machines,
irrespective of it's method of storage or accessseaability
There are similiar parallels in the bioinformatics and pharma
industry. Essentially it's capitalism gone beserk with patents being
used to continue obsolete business practices. But that is another
story.
