If you algorithm is standard just google "FPGA/ASIC IP provider" (of which there are many, eg H264 etc) and pay the price, your results will be optimal and cheaper than doing it yourself - assuming you never have before.
If your alogirthm is custom then you are either going to make a horrible job of it as you learn HW as you go, it takes years to get optimal and reach the clock speeds, area, and QoR/Test coverage numbers needed for production Si. Alternatively you could hire a HW team who will cost you a pretty penny to get it done, or outsource - also not cheap but it allows for risk reduction.
How many gates isnt just a question of counting "*" and "/" and scaling (although back of napkin will give you a general feel). Practically any C/C++ you write is going to be very sequentially orientated, this results in algorithms that probably have better parallel implementations. Whilst you might now be thinking threads, or separate processes we are talking HW parallelism, which is far more fine grained than threads, than SW parallelism. Further any integers you have may be optimizable to less than 32 (eg 1 bit or 3 bits) thus saving a large amount of HW area. Finally you didnt really say what sort of performance you want - if its 1MHz and 1 word / year of I/O then I suspect you could build some very clever hardware to do it all a few gates but if its 1GHz and 1 Giga Words/sec then area might expand as you will need to duplicate the circuit in parallel. Finally the speed at which you process data will affect latency (time from input to the first correct output) which is often a killer in real-time or other systems (eg. If you put LCD TVs side by side you might notice some are running several seconds behind whats being broadcast - this is because as it received the image some are doing more video processing to clean up the image - latency )
So at this point I would recommend looking into SystemC (based around C++), SystemVerilog (so so ) and then a raft of tools to help you do the job. These tools are called "High Level Synthesis" (HLS) tools and they arent cheap but they do cut down on man hours manually converting algorithms, but you will still need to be able to think extremely low level as bad code results in bad gate count - no matter the language.
Disclaimer: I used to work at one of the companies that provides synthesis tools, for >10 years converting C/C++/SystemC to HW quite often for a service fee. I can tell you we never had a design that cost under 30K and most were in the 100s to millions of USD.
Good article, and with enough comment maybe MS will reform the OS. You should compare XP to Win2K - its super fast! Win1.01 loads... but I digress!
The main point that I wanted to seed into peoples minds was that Slashdot articles on technology are usually chided for being one sided (pro Linux, anti-that, narrow minded something) but what is never mentioned is they are also often culturally one-sided.
As I no longer live in the US, having lived all over, and for quite some time in Asia I see that technology is often developed and marketed as if it would work globally. Thats not always the case...
I pick particularly on your comment about TV on the PC. In Japan, for example, most average young things have an apartment only slightly bigger than the bed. So PC + TV is quite a space saving attraction here, although I don't think that's why its in Vista.
The other oddity you could add to your Windows woes, although not specifically Vista related, is that often Asian Windows maintain the ALT+Alpha key strokes from English versions despite having no connection to the action it performs. (Alt+A is save-All normally, but in Chinese there is no A in "save all"). So big bouncy GUIs help those that don't have a memory as large as the national library of congress to store all those key strokes.
There are other subtle things when comparing a product in another country - but these two strike a powerful example of how designers and critics alike should consider a product in its surroundings.
We started with borrowing local scanning resources and manually page flipping. That's one page per every 5-6mins! Then we bought our first LPT scanner and it was a little faster but ate pages....
...ack depends on what you want to do. Like most people say do you want to totally destroy your books? How much do you want to spend? Are you ever going to use those physical books again?
If its just low cost and personal copy with reasonable quality and you have LOTS of time then.... just grab a copy of OmniPage OCR v11, a HP ADF scanner [ hp scanjet 5490cxi (C9863A)], a copy of Adobe Acrobat and get a professional company to despine your books.
We spent a total of $800 on software/hardware to do this. We spend, on average, about 50 - 200 hours per book to process it - thats scanning, OCR, OCR proofing and format rework and then final PDF output.. Some of the books we're doing I have given to students to work on. They'll do it for next to nothing;-)
Its possible to outsource this to companies to do this work for you. For example Crowley do this and they also handle large documents. You have to be aware of how they are going to process your book and the copyright problems. However, as someone said, some don't care about copyright and some do (eg Kinkos). Again this comes down to do you care about the books and how much you wanna pay for a digital copy...
In our case we don't make money off this site so we can't afford to out-source. So our biggest problem now is how we are going to get the over-size PDP-11 documents into PDF. The Minolta PS7000 looks like the beast we need but its way too expensive for a non-profit. We'll probably be out-sourcing and eating the costs.
My suggestion is to either go the HP scanner+Omni+Adobe PDF route OR out-source it if you can afford. At least with the out-source option you get to keep your books intact.

I dont want to come over as a shill so I am going to present the 4 main competitors for HLS tools;
1) Calypto Systems, formerly Mentor Graphics' tools before spin-out ( http://calypto.com/en/products/catapult/overview )
2) Forte Desgin systems ( http://www.forteds.com/products/cynthesizer.asp )
3) Cadence C2S ( http://www.cadence.com/products/sd/silicon_compiler/pages/default.aspx )
4) Impulse C ( http://www.impulseaccelerated.com/ ) - this is very reasonably priced but has its limitations.
5) There are some open source things out there, I wouldnt recommend them as they are quite in their infancy.

We, that is two of us, have been doing this since 1997. Our site Internet Technical Documentation Archive (ITDA) houses a lot of freely available Field Service Manuals.

I see it uses port 27960 just like Q3 did and its based on Q3 but the ip_masq_quake doesn't work on my Linux firewall...
...anyone have any ideas on how to fix this?
Man they rocked, really the best and I would pay to have them on DVD or VHS.
