Hi Bhaskar, What do you mean with "rubber"? Some sort of souvenir? I think this is a consequence of my not being a native english speaker.

There's definitely plenty of bandwidth; we'll probably only be hooking up 4 of the data lines of one link port to the FPGA, and that's still several orders of magnitude more throughput than we actually need for this particular application. I looked at your board (and several other similar ones), but it's way overkill for our application. We basically need the compute power of one TigerSharc and about 200 kB/sec aggregate I/O to eight serial interfaces of various types. -- Dave Tweed

However, let me share another 'rubber' story. Most people in India (possibly from the entire sub-continent) refer to the device used to erase writing made in pencil as 'rubber'. I don't know about other countries, but it's called 'eraser' in the US. If you said 'rubber' in the US, it will most certainly be interpreted as the slang for condom. An (Indian) acquaintance of mine came to the US to attend grad school several years ago. He was to work with a (lady) professor as a research assistant. During the first few weeks, I guess he was working on an assignment and needed to erase some of his work. He promptly went up to his professor (in the presence of several other students) and asked for a 'rubber'. Needless to say several minutes of confusion and embaressment traversed the room, with the professor repeatedly asking him to repeat his question...the poor guy couldn't believe his accent was that bad (until one of the other students was kind enough to explain the slang).

Here in the US, although usually in the plural, "rubber" also means overshoe. (Don't forget to wear your rubbers, dear.") The Indian and English usage is older than ours. Rubber gets its name from its use in rubbing out -- erasing -- unwanted pencil marks.

(Don't forget to wear your rubbers, > dear.")I have an uncle who went to high school in the 60's. His English teacher was a very frail woman about <exageration>180</exageration> years old. The class was performing exercises on sentences the teacher read aloud. One sentence went something like this: "Mr Johnson, although he should have known better, left home without his rubbers." Upon hearing this, a big guy could not contain himself and burst into guffaws. The teacher knew full well his interpretation of the sentence and attempted to restore order. She crossed the room, grabbed the student by the shirt and attempted to give him a good shaking. She lacked sufficient strength (and mass) to effect any shaking in her target, and instead ended up shaking herself. At the sight of this, the rest of the class lost it too. -- Jim Thomas Principal Applications Engineer Bittware, Inc jthomas@bittware.com http://www.bittware.com (603) 226-0404 x536 Quidquid latine dictum sit, altum sonatur.

I should mention it to S&M (sales & marketing hates it when I call them that) as they were pretty popular. I could break some fins off of the Hammerheads for you to represent our SharcFIN though :-) I'll most likely be at the Embedded Systems show on Analog Devices booth if you want to drop by. ---- Ron Huizen BittWare
