At such low prices why would anyone be worried about it?  Toss it out and buy a new one when you need an update.

Well, for things like the FPGA Arcade (a daughter board perhaps?), these would but useless because we need to have the ability to update firmware.   Development with these would be a nightmare when you're throwing them out every time you want to test your code as you are writing it.  They apparently have sort of simulation software to ease the development, but there is no substitute to throwing the part into a board and testing it.  Neat chip though for one-time uses - like a USB<>serial, SCSI<>IDE, etc. only interfaces, or a commercial product that will never change.


Or maybe just go with a socket.  Toss out the old chip, insert the new one and apply the update.....

This is the thread for stuff that as a minimum can be reprogrammed at will....


Hmm.....as opposed to unwillingly programmed?

These chips are programmable.....but only once....hence the discussion to use a chip socket when you want/need to update your device.....This same concept is used to update classic Amigas with updated Kickstarts.  So what's the problem?

Kickstart ROM chips are slow, expensive and difficult to update.

We want machines that are fast, cheap and easy to update.

The whole point of an FPGA chip is that you can keep reprogramming it over and over and over again for free.  The XMOS chip is the exact opposite philosophy.


Why do insist on reading things into what I wrote that simply don't exist?  I never implied nor stated that Kickstart ROMs were fast.  Do you have a reading disability or are you just looking to be difficult?

The 4 core version has 64k of ram and 28 i/o pins, it wouldn't even be able to emulate a c64. The most expensive one ($27.11) has 256k ram & 256 i/o pins, which is starting to get better. I don't know if you can run code from ram, but it only has 32k of otp rom. I'm not convinced you could emulate a c64 on that either but I don't mind being proved wrong.
 
Feel free to discuss it somewhere else, but if all you're going to do is drool over it and not actually try building something with it then you're just wasting your time. It has absolutely nothing to do with the FPGA replay & cannot possibly emulate an Amiga.

Who is drooling?  I just stated that if people wanted to consider using an inexpensive but fast, write-once programmable chip that they should consider using a socket.  I never mentioned C64s, pins or anything else.  You're as bad as ChaosLord when it comes to making assumptions and being difficult!  That's one of the reasons why I rarely post here because guys like you and ChaosLord have turned this board into a digital freak-show that you use to bully and push other people around to satisfy your massive cases of overgrown ego.
