Short for Very Long Instruction Word, a microprocessor design technology. A chip with VLIW technology is capable of executing many operations within one clock cycle. Essentially, a compiler reduces program instructions into basic operations that the processor can perform simultaneously. The operations are put into a very long instruction word that the processor then takes apart and passes the operations off to the appropriate devices.
Compare with RISC and CISC.
Abbreviation of very large-scale integration, the process of placing thousands (or hundreds of thousands) of electronic components on a single chip. Nearly all modern chips employ VLSI architectures, or ULSI (ultra large scale integration). The line between VLSI and ULSI is vague.
Short for VESA Local-Bus, a local bus architecture created by the Video Electronics Standards Association ( VESA ). Although it was quite popular in PCs made in 1993 and 1994, it has been overshadowed by a competing local bus architecture called PCI.
- VME bus
(VersaModule Eurocard bus) A 32-bit bus developed by Motorola, Signetics, Mostek and Thompson CSF. It is widely used in industrial, commercial and military applications with over 300 manufacturers of VMEbus products worldwide. VME64 is an expanded version that provides 64-bit data transfer and addressing.
Short for virtual machine monitor, in virtualization technology it is the host program that allows a computer to support multiple and identical execution environments. The VMM provides the underpinnings for virtualization management, which includes policy-based automation, virtual hard disk, life cycle management, live migration and real-time resource allocation. You can basically think of the VMM […]
Found in Windows 9x machines, VMM32.vxd is the virtual device driver library that contains virtual device driver files needed for system start up. VMM32.vxd is different for every machine; therefore, if it gets corrupted, it cannot be copied from another computer; it’ll need to be rebuilt.
