Guide to Weitek chips, need little help

[achtung049]

Hi!
I think everyone here knows Weitek company. This company has not survived so long, but it made a lot of unusual and rare chips. I'm tired of every time to look for old datasheets to find out what I see - I decided to collect all the information in one topic. If you have any additions or you want to correct a mistake - please write here, and I will make changes to the list.
I hope this little guide to the marking and purpose will be useful to anyone except me

OK, let's go!
(I have omitted all markings everywhere except 4 digits indicating the purpose of the chip - this is enough I think. You can later specify more details)

Here is my research:

No information. Could not find any photos, datasheets and so on, only a few references. Purpose unknown. Existence of chip has not been confirmed.
Purpose known. Purpose chip is clearly indicated in different sources, but datasheets and photos not found.
Photo only. Existence of chip with this label confirmed, but I have no data, picture only.
FP is floating point, ALU is ALU
Wherever it is possible, the function of chips described according to the datasheets description - so often found less common terms, like a "integer processing unit" (instead CPU) and "Full floating point data path" (instead FPU)

Thank you that you have read!
Please indicate inconsistencies and add information if you have it. There is not enough information about this company, but their chips are expensive, rare and beautiful - I think would be useful to finally collect information about them in one place.

* 1st correction (thanks John and isa-d):
1164 64b FP Multiplier/Divider (used in SUN-4)
1165 64b FP ALU (used in SUN-4)
1163+1164+1165 is a complete replacement of the 386

** 2nd correction (thanks Birdman):
3170 Full FPU (used in SPARCstation 1)

Very useful, I'll see if I have anymore info

susl45 also collects weiteks, I remember he had some odd ones come through AVICC

[isa-d]

I'm a little confused with this

1167 32b Abacus 80386 FPU (one chip 1163+1164+1165 realisation) 1986

looking to this post (last post)
http://www.cpu-world.com/forum/viewtopic.php?t=13461&highlight=weitek+1163
seem 1163+1164+1165 was a 386 replacement, not a FPU

[isa-d]

about this

Power uP SPARC CPU (modified 8601 - may be 8701 in diff. pack. ???)

its number is 2000 and without heatsink looks completely different than 8701
... but same pinout like 8601 and 8701

[achtung049]

OK, thanks!
1167 architecture:
https://upload.wikimedia.org/wikipedia/commons/thumb/9/98/Weitek_WTL1167_arch.svg/800px-Weitek_WTL1167_arch.svg.png

about 1167 - I can't find datasheets for this chip. In many sources it is mentioned as a co-processor, including 1163 datasheet:
http://pdf.datasheetarchive.com/indexerfiles/Scans-001/Scans-0035402.pdf

about Power uP - In many sources it is mentioned as a 80MHz version of WTL 8601. Elsewhere so it called the entire series Weitek SPARC, but on the appearance these three different processors. And they all have the socket PGA-207.

[Birdman.]

3170, 3171 and 3172 should all be complete SPARC FPUs. I've taken die shots of all three and they have some differences but many similar areas on their dies like most of datapath. I hope someone finds some information about their functional differences so that we can know why dies have those differences.

In addition to those three I've also released 3132 and 8601 die shots and I have 8136 and 8137 waiting for release. I hope those die shots are useful and give some new information. Unfortunately, some Weitek chips have been too rare and expensive for die shots so far like x86 coprocessors.

[achtung049]

Thanks, updatet!

[Vlask]

Think that P9001 is only ISA->PCI bridge, not graphic chip. Never seen one standalone. Only in combination with P9000 on PCI Diamond Viper.

Same is P9130 - that should be video acceleration addon chip, not graphics chip. Used together with P9100.

[achtung049]

Excellent, fixed! Thanks!

[magictom]

I have no hard proof of this, but always thought several of the early Weitek chips were clones of TRW signal processors, and followed their numbering convention. I.e.

Weitek TRW

1004 = TDC1004 64-bit Digital Correlator
1010 = TDC1010 16 x 16 TTL Multiplier
2010 = TMC2010 = TMC2210 16 x 16 CMOS Multiplier

It would be great to see some documentation to that effect, though ..

[achtung049]

Wo-ow!
many thanks magictom and UMMR - it's really important piece of the puzzle! I was not able to find any information about these chips...

WTL1066 Register File 6-port (32x32)
From 1986 IC Master

[CPUShack]

There is also a Weitek WTL2044 16 X 16 parallel multiplier-accumulator

[CPUShack]

also:
8000 integer processing unit (CPU) 1987
8032 32b single-precision FP processor 1987
8064 64b double-precision FP processor 1987

This is a Weitek architecture (RISC but not MIPS)
the XL8000 is integer only (software for FP)
The 32 and 64 are integer AND FP, not just FP
