  Weitek - Wikipedia, the free encyclopedia
Weitek Corporation was a former chip-design company that originally concentrated on floating point units for a number of commercial CPU designs.
Weitek also worked with HP on the design of their latest PA-RISC design, and sold their own version known as the RISC 8200 which was sold as an embedded design and saw some use in laser printers.
Weitek adaptors were fairly successful in the early days of the 486 market, but fell from use as less expensive systems were introduced by a host of new players in the mid-90s.

 Weitek/AIPS/DDT
The Weitek 'POWER uP' chip, based on the Weitek W8601 Sparc CPU, is a replacement for the Sparc 2 or IPX CPU and uses clock-doubling technology, on-chip caching and architectural improvements to significantly improve the preformance of the Sparc 2.
With the installation of the new Weitek CPU, the total CPU time taken was 58% of that before the installation for the medium DDT test and 57% for the large test.
The accuracy results were unchanged by the installation of the Weitek CPU, indicating that the Weitek chip has retained the IEEE floating point compliance of the Sparc 2.

 The Free Information Society - Mathematical Coprocessors
The Weitek Abacus 3167 works with a 386 CPU but requires a 121-pin EMC socket in the system; this is *not* the same socket used by a 80387 or compatible chip, and some computers, such as IBM's PS/2s, don't have this socket.
Weitek 1167 This math coprocessor was the predecessor of the Weitek Abacus 3167.
In contrast to the Weitek 3167, the 1167 did not have a square root instruction; instead, the square root function was computed by means of a subroutine in the Weitek transcendental function library.

Weitek Corporation was a former chip-design company that originally concentrated on floating point units for a number of commercial CPU designs.
During the early to mid-1980s, Weitek designs could be found powering a number of high-end designs and parallel processing supercomputers.
By 1995 the company was almost dead, and in late 1996 the remains were purchased by Rockwell Semiconductor and quickly disappeared.

 Weitek Power for Windows
Weitek is probably best known for its line of math coprocessor chips that speed up numeric calculations by several orders of magnitude.
But Weitek is also a leading developer and manufacturer of graphics coprocessors, and the Weitek Power for Windows graphics board is its latest offering.
The Weitek board was a joy to use, producing crisp, flicker-free displays in 640 x 480, 800 x 600, and 1024 x 768 video modes, with excellent color and image resolution even when using a relatively inexpensive multi-frequency analog monitor.

After Weitek went out of business in 1997, it was absorbed into the Brooktree Division of Rockwell Semiconductor, which survives as an independent spin-off, Conexant Systems.
Although the Weitek P9000 did not support three-dimensional graphics, it was popular with advanced computer users, supporting OS/2 and Linux platforms in addition to Windows-based applications.
Weitek followed the successful P9000 with the P9001, nicknamed the "Viper", a peripheral component interconnect (PCI) version of the P9000.

 WEITEK TO SUPERCHARGE 80386 CPUs WITH 1167 MATHS CHIP - Computer Business Review
Weitek Corp hopes to play a key role in transforming 80386-based personal computers into engineering workstations with its forthcoming Weitek 1167 floating-point co-processor for the 80386.
Weitek claims that in graphic applications, an 80386/1167 system can transform and clip up to 60,000 vectors per second compared with only 10,000 per second using the 80386-80287 combination, but still behind the 68020-based stations from the likes of Apollo and Sun, which can transform and clip about 100,000 vectors a second.
Weitek reckons that the part will also be useful applications that require massive amounts of arithmetic computations, particularly simulation.

In 1988, upstart semiconductor manufacturer Weitek released math coprocessors that were able to perform most functions featured by the Intel 80387 math coprocessor when matched with the wildly successful 386 processors.
Weitek released models including the 1164/1165 Weitek floating-point unit (FPU) and the 1167 Weitek math coprocessor.
The Weitek 3167 replaced the 1167 chip for the 386 processor while the Weitek 4167 was marketed as a numeric coprocessor matched to the 486 microprocessor.

 Weitek 4167 co-processor family
Weitek 4167 is a high-performance Floating Point Unit for Intel 80486 family of microprocessors.
To communicate with the Weitek 4167 the CPU reads from/writes to memory space designated for the FPU.
This communication method was beneficial to previous generation of Weitek 3167 FPUs because it was faster than I/O communication method used by 80387 co-processors.

 Int 31H Function 0800H   (Site not responding. Last check: )
When this function is called, the DPMI host either creates page table entries that directly map the physical addresses requested and returns the linear address of the created page table entries, or else just returns the linear address of the memory region that is already used to map the requested device.
For example, if the client attempts to map a Weitek coprocessor and the host already has a linear region set up to map the Weitek chip and virtualize it, it would simply return the linear address of the existing region.
If the host does not virtualize the Weitek chip, it would create 16 page table entries that map the 64 KB Weitek address space and return a linear address corresponding to the new page table entries.

 4.3.7 QCD on the Connection Machine
Moreover, every operation in Paris is an atomic  process; that is, two operands are brought from memory and one result is stored back to memory, so no use is made of the Weitek registers for intermediate results.
CMIS allows effective use of the Weitek registers, creating a memory hierarchy, which, combined with the internal buses of the Weiteks, offers increased bandwidth  for data motion.
However, since there are two CM chips for each Weitek floating-point chip, the floating-point hardware is effectively wired together as an 11-dimensional hypercube, with two wires in each direction.

 Sparc Linux BogoMips Page
On the home page of ObsolYte!, I once claimed that the SparcStation IPX with the Weitek Powerup is as powerful as a Pentium 75 because I read its Bogomips value to be similar.
From SPECint92 figures, the Weitek 40/80 MHz SPARC processor is somewhere between a 486-33 and a 486DX2-66.
And yes, bogomips are pretty bogus indeed - for the most part, I've noticed that, particularly on the Sparc Linux implementation thereof, the bogomips value is almost always the same or very close to the Mhz rating of the CPU.
