Windows device driver information for Weitek Power9000 (PCI-Bus)

The Weitek Power9000 (PCI-Bus) is a driver distributed and manufactured by Weitek Corporation which was formerly a chip-design company concentrating on floating point units for CPU designs produced commercially. Weitek developed math coprocessors for several systems which include the Motorola 68000, and Intel i286 systems. The Weitek Power9000 (PCI-Bus) is a computer bus used in attaching device hardware on computers. It can either take the form of an integrated circuit which is fitted onto the motherboard itself called a planar device or it can be an expansion card that can fit into a slot. The Peripheral Component Interconnect (PCI) bus is commonly found in computer modems where it has displaced ISA and VESA local bus which are the standard bus expansion. A PCI card used in computers include: sound cards, network cards, USB, modems, disk controllers, etc. A PCI provides a separate memory as well as an I/O port address space for x86 processors.

In a system, firmware queries all PCI buses via the PCI Configuration Space to find out the devices that are presently used and the resources that each needs, after which it allocates the resources and identifies which device needs the resources. The PCI configuration space contain a small device type information which is able to help the Operating System choose the device drivers that it needs. There are also PCI Latency Timers which are mechanism for PCI bus-Mastering devices in order to share the PCI bus fairly. The specifications of a conventional hardware in normal computers are as follows: 33.33 MHz clock with synchronous transfers, peak transfer rate of 133 Mb/s (133 million bytes per second) for 32-bit bus width (33.33 MHz โˆšรณ 32 bits โˆšโˆ‘ 8 bits/byte = 133 MB/s), 32-bit bus width, 32- or 64-bit memory address space (4 gigabytes or 16 exabytes), 32-bit I/O port space, 256-byte (per device) configuration space, 5-volt signaling, and reflected-wave switching. It is highly recommended you run a free registry scan for and Weitek Power9000 (PCI-Bus) errors before installing any driver updates.
