Hallo, the C-One can be many things. Lets not think so outright that the C-One is strictly about "Retro-Computing". It is in ways as ultra-modern by concept that hardware can be reconfigurable. One chip that can be turned into different kinds of hardware. That is a feat that will take incredible CPU power to make as virtual machines. With FPGAs its not virtual and its not emulated. Think of an array of silicon gates that can be rewired on the fly without use of soldering gun or expensive fabrication labs. The C-One's C-64 mode and compatibility is a feat about retro but think of tha past and the future being put into one point. Futuristic hardware concepts can literally be "proven". Now we can make hardware alot like we can make software. We can make efficient hardware with the same efficient principles of efficient software programming with understanding of hardware. What about real-world prototyping. Developers will love this. In all reality, we can even be a DVD Player as well. The future of the C-One would be the use of FPGA technology and a new revolution of software that incorporates hardware add-ons on CD-ROM. Now imagine this, I have this super fancy SuperNintendo cartridge, I can now incorporate a SuperFX chip all on CD-ROM. How, it is called VHDL the revolutionary bridge between software and hardware. Our ability to reprogram the hardware via software. The ability to incorporate our very own hardware in every CD-ROM we sell. Now, we can distribute hardware in 10-15 cent CD-R disc (CD-ROM). This is some of many possibilities we can see. This is only the beginning. Reconfigurable hardware is used in even modern DVD Players and digital setop boxes and other luxeries and state of the art products.

Close. You're actually describing a PAL. An FPGA is more similar to RAM. Think of it as the high speed memory of programmable logic devices. When it loses power, it loses it's programming. An FPGA usually reads it's configuration on power-up from ROM or a PC's parallel port if you're prototyping. There's really no "burning" involved.

You clearly haven't read the machine's specifications. This is a 65816, not a 6502 or 6510. It has a 24-bit address space, not 16-bit. It has 16-bit access to memory (through an 8-bit pipe), not just plain 8-bit. It has 16-bit internal operations, not just 8 bit. It runs at 20 MHz, not 1.022 MHz. The built-in SID Emulation contains a multitude of voices, not just three. It contains graphics hardware that is many levels above that which a regular C64 came with in 1982. Maybe not exactly competitive with today's multi-gigahertz 1600x1200 ultra-fast 300fps-in-Quake3 hardware, but most people don't really need that.

In other words, given that it takes 500 to 1000 Megahertz to emulate a regular breadbox C64 and a couple of 1541 drives (and even then it STILL isn't 100% accurate), it would likely take a machine somewhere in the 10 to 15 Gigahertz range to reasonably emulate the Commodore One and whatever standard peripherals you add to it, if only because of the speed of the Commodore One relative to that of a breadbox C64.

Try again. Translation: Jeri is not a software engineer - she is not a programmer, and has said so herself. It is common in the C64 scene to work together with others on a project - one person does the music, another the graphics, and another handles the code that ties it all together. The same can be said for the Commodore One. Jeri designed and implemented the hardware, and now she's hoping to find someone who can design and implement the software, or part of it anyway. Some of us who support this machine believe (and the Webpage also mentions this) that JOS/Wings might very well BE that software. (And yes, JOS/Wings exists and runs now, on existing hardware. I've used it - it IS that good)

I'd just like to point out that I've started writing IDE routines for the C1. Low level routines are done, basic FAT32 support is there, and I'm currently adding FAT16. ATAPI + ISO 9660 is probably up next, so that it'll be possible to boot from CD-ROM as well.
As there is only 3k of space in the boot rom these routines are fairly specialized, but the source is open and it shouldn't be too much work to make a real driver out of it.

In that sense an FPGA is no less serial on FFTs than a CPU, right?

Sure, you have to clock the FFT data into the internal memory of both an FPGA and a CPU. However, on an FPGA, unlike on a CPU, you can make as many multiply-accumulate units as you want up to the size of the FPGA, all operating in parallel. Large n-point FFTs can be parallelized with up to n multipliers.

FPGA Graphics Card? by BigDish · 2003-02-23 05:29 · Score: 2, Interesting

Here's an interesting thought. I see someone mentioning that some cryptography company uses FPGA's on a PCI card in a PC. What about taking that one step further, and making the GPU on video card a FPGA? Imagine if, when you launched a game, it would be able to reconfigure the card optimally for that game. Rather than leaving parts of the GPU unused, it could convert them into something it can use.

This would also allow graphics cards to be upgraded, for instance, if today's graphics cards were FPGA based, DirectX 9 support could be added to existing cards.

Are we going to see this technology this year? I doubt it. But 5 years down the road, I bet your graphics card will be based on an FPGA.

Unfortunately, your idea of implementing an FPGA into a PCI/AGP video card would result in horrendous performance issues.

1. Video cards curretly are limited by the speed at which they apply a transform to a bitplane (1600*1200 anyone?).
2. Very fast transforms need to be applied to MILLIONS of memory locations, very quickly
3. An FPGA is tuned to apply MILLIONS of transforms to a single input, very quickly.
4. Your high-end vid card expects uber-fast data
fill rates from your uber-fast 2.8NANOsecend drams.
3. your FPGA is rated likely rated at 60MILI to 30MICRO seconds, in Asynch mode, 90+Microsoconds in Synchronous.

Until fpga's are available in 2.5NANOsecond SYNCHronous speeds, you will NOT find them on you video cards.

True, these are all limitations that need to be overcome. But that's why I said you won't see it today or tomorrow. 5 years ago, who would have though we'd have the kind of storage, memory, 3d peformance, and graphics on our desktops we do today. 5 years from now, who knows what we will have. I'm SURE this will happen eventually, it's a question of when, not if.

This was supposed to be the promise of Creative's Sound Blaster Live! series of cards, which was based on a programmable chip.

Creative never lived up to the hype... because hardware companies are in business to sell hardware--an FPGA based graphics card in unlikely, because nVidia cannot sell a new one to high end gamers every six months.

Re:FPGA Graphics Card? by BigDish · 2003-02-23 11:33 · Score: 1

I wouldn't say that. Every 6 months we can get a new larger/faster FPGA which will translate into faster graphics. The FPGA's will still have to be upgraded once their capabilities are maxed out. I sort of look at it as the melding of software and hardware.

Undocumented instructions by yerricde · 2003-02-23 05:38 · Score: 1

No, you can't use a 65c816 to run Atari 2600 programs natively. Because its graphics system is so dang underpowered, an Atari 2600 program must use the undocumented instructions of the 6502 that were removed to make room for the new instructions of the 65c02 and 65c816.
