Z380

Maybe the all-knowing All knows what kind of beast this is - the Z380. Information
is needed more than the fact that it is 32-bit (it seems). I would like to know
at what clock frequencies it can operate, its capabilities (new commands
relative to the Z80). And finally, the most important thing - is it possible to create a Spectrum
based on the Z380?

The Z380 is a sixteen-bit processor. The address bus is 32-bit. For all
documented and some undocumented (half index registers)
commands it is compatible with the Z80. It has many additional commands for working with sixteen-bit registers. Sixteen-bit arithmetic operations,
block transfers, multiplication/division, sixteen-bit input/output..
There is a proprietary ZILOG book in English, where all this is described.
At taco frequencies (from those that I saw on sale) up to 16 MHz.

I suppose the creation of Spectrum on Z380 it is possible. And, quite possibly, Sprinter-2
will be based on it.

percent of the Z80 family, the latest generation.

RP> Information is needed more than what it is 32-bit (apparently).

order the corresponding literature from zilog by mail or buy from
distributors, or find it on the Internet.

up to 33 Mhz (according to the manual that me)

RP> capabilities (new commands regarding Z80). And finally, the most important thing -

yes, a lot. 4 sets of alternative registers (all registers are 32-bit
, in the sense - extended).

RP> is it possible to create a Spectrum based on the Z380?

everything is possible, but many programs will not work due to
the use of undocumented features.

Good Luck...

In the fall-winter of 1996/97. (that is, a little over a year ago)
Nicron published a whole series of articles about subj. The architecture, electrical parameters and
command system of the new processor were described in detail in Russian. The series of articles continued in more than twenty issues of the newspaper - from the 6th to the 27th, if I'm not mistaken. People, if you can’t raise these Nicron numbers, write to me; We’ll figure out something to do (for example, it won’t be difficult for me to make clippings from all these issues, make a
selection. But how to send it out? - It’s a pretty big volume...).
Suggest options.

With respect -
Vladimir.

So, do you already have a Spectrum-compatible computer on the z380? ;)

As you said in a letter to Ivan Mak, the Z380 has a Z80 mode. Isn't this mode completely compatible with the native Z80? And as for undocumented commands
this is already clear - where else can the command system be expanded? By the way, I heard that the Z380 has commands for multiplying and dividing registers? Correct
if anything is wrong.

WB>> not sickly...). Suggest options.

IM> In one .trd file and in echo, if allowed.

Yes, there will be about 40 KB in the text archive, if not less...
You can also throw them in a ZIP file.

I willingly believe that it’s not bad, but the texts seem to be packaged very well. Still
try to put everything together and pack it up.

well, it’s not original, it’s original in Africa, and if you compare it by demos
then all non-pentagons are completely crooked.

Well, if 40k, then you can do it in a ZIP file.
I wonder what is written there? :)

Now WB will figure it out and let's drop it. Yes, there is a translation of documentation and
translated information from the ZILOG website.

Sincerely, Alexey Ivanov

I have the first four publications on the subject. About 25 kilos.
Who needs it? Or should we wait for the full set?
WB said he will do this no sooner than in a week.

Is the site of the zilog itself satisfactory?

I didn’t go into such details, but these devices have a cache
of data/instructions -> it changes. strongly.

RP> As you said in a letter to Ivan Mak, the Z380 has a Z80 mode. This mode

yes, it does.

RP> isn’t it completely compatible with the native Z80? And as for undocumented

, what does REAR mean? There are many modifications of the Z80, which still
have minor differences.... go to the zilog.

RP> commands, this is already clear - where else can you expand the command system?

you can.

RP> By the way, I heard that the Z380 has multiplication and division commands registers?

afaik exists, starting with Z180.
