Replying to people (was TRS-80 model II)

by MPritchard＠EnsembleStudios.com

Just a note to people: when you e-mail someone directly; don't use an email-address that has something like "your name <yournameDIE.YOU(a)SPAMMERmydomain.com>" in it. Using Microsoft Outlook (which I do), it just shows <your name> with the SMTP portion hidden. After the mail bounces, I'm less inclined to type the whole message again and edit your user name. So that reply to you offering to sell you the complete Altair for $50.... well, you didn't get it. I mean, it's a direct e-mail, not the mailing list. If you think I am going to spam you... come on. Ok, now that, I've jumped all over Arfon, I have to say it's nothing personal and I apologize in advance. it's just not the first time that it's happened. it's just that I don't even see anything until the mail bounces. -Matt Pritchard

Dear Mr. Whitehead, You could have used some discretion like most of us on this list and just read the strings you found worthwhile. Instead you insult virtually everyone on the list and have created yet another flame war which has no end in sight.

64bit data 128Bit address...Re: Building a Z-80 (64bit!

by allisonp＠world.std.com

< So, while a 256 or 512 bit data bus is usefull (and < already in use in main frames - only called data path), < even a 128 Bit address bus is just nonsense. There is some truth to this. DEC went to 64bits as they knew 32bits were not enough for some applications. They were also trying to design for the next 20years to repeat the life of the VAX (32bits). Now, having a large address space isn't completely about filling it. It's about having addressing modes and arithmetic adaquate to deal with large data objects. In the 32bit model 4gb is the limit without thrashing. Those limits was exceeded by disk farms with tens of Gigabytes of databases and solving large mathmatical models. The current example would be doing windows graphics programming (1280x1024x16m) using only 16bit pointers, you do a lot of thrashing to get the the next 64k chunk and there will be a lot of them! That was the problem that spawned the VAX! Brief history lesson: The PDP11 was reachhing the point where a fully filled machine (4mb of ram) could not process in one lump the large problems like weather models or MRI data. It was NOT a speed issue it was 16 bits made for too small a data pointer. Also doing 32/64bit math required more steps (or FP hardware) as the registers were all 16bit. So to add two 24bit numbers on a PDP-11 required multiple steps and that was a speed impact. Going to 32bit registers made that a single instruction and paid back as speed without processors running at faster clocks. If it were speed the 11/74 would have been an ongoing event rather than the 4-6 than did get made. The birth of the VAX (and DGs Eclipse) grew >from this need. So computer designers bumped the size of things to assure they could comfortably address the likely largest object they can resasonably expect to see for some time to come. Not so they could have 2^64bytes of ram but because they already have 2^40bytes of disk farm! All this was no surprize to computer designers. They foresaw it in the 60s knowing that larger memories and disks were needed to solve the problems that were growing. The datapath issue is strictly about speed as the VAX could have an 8bit data bus (in a trade for speed) like the 68008. While it has a big effect on speed it has no interaction with addressability. It's addressing the system problem of multiple devices competing for the common resource (MEMORY). By making the datapath wide you can grab several bytes at the same time and while the cpu is dealing with that the ram is available to run a IO cycle to a disk system or other IO. How big wide enough is, that is determined by how much silicon you have. Allison

I'm not objecting to the thread; I'm simply pointing the group towards an already extremely comprehensive source of information, because this is a better practice than repeating stuff that most folks here have already seen many times before.

That's the one I'm thinking of - the amount of memory you get on > the same area of silicon doubles every 18 months. Basicly I think its about integrations and transistor equivalents, but this is just linear to the size of memorys. In fact, to come back to the original question, Arfon just took doubling of address space and doubbling of data bus width for the same thing, but in fact they are two different functions - widening data bus is linear, while widening address bus is to the square (sorry, my mathematical english just stops here). This means doubble the data bus just doubbles the date transfer rate (the only thing the data bus is needed for) or w'=w+w. But doubbling the address bus is putting the address range (and thats what the address bus is for) to the square or r'=r*r. So, while a 256 or 512 bit data bus is usefull (and already in use in main frames - only called data path), even a 128 Bit address bus is just nonsense.
