I2O
Intelligent Input/Output (I2O) is a defunct computer input/output (I/O) specification. I2O was originally designed to make use of the Intel i960 microprocessor as the I/O offload engine, bringing channel I/O to the PC. I2O emerged from Intel in the mid 1990s with the publication of the I2O specification in 1996 by the Intelligent I/O Special Interest Group, which dissolved as of 13 October 2000. I2O's principal architectural components included the I/O processor (IOP) and a split device driver model, with an OSM (OS Module) running in the host operating system and a HDM (Hardware Device Module) running on the I/O processor. This formally separated OS-specific driver functionality from the underlying device, and the two software components used message passing for communications. This split is suggestive of another initiative in which Intel participated at the time, the Uniform Driver Interface (UDI), which sought to establish a common device driver interface spanning multiple ...

Uniform Driver Interface
The Uniform Driver Interface (UDI) is a defunct project developed by several companies to define a portable interface for device drivers. The Uniform Driver Interface (UDI) allowed device drivers to be portable across both hardware platforms and operating systems without any changes to the driver source. With the participation of multiple OS, platform and device hardware vendors, UDI was intended to be the first interface which was likely to achieve such portability on a wide scale. UDI provided an encapsulating environment for drivers with well-defined interfaces which isolated drivers from OS policies and from platform and I/O bus dependencies. In principle, this allowed driver development to be totally independent of OS development. In addition, the UDI architecture was intended to insulate drivers from platform specifics such as byte-ordering, DMA implications, multi-processing, interrupt implementations and I/O bus topologies. While UDI could potentially benefit open source ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intel I960
Intel's i960 (or 80960) is a RISC-based microprocessor design that became popular during the early 1990s as an embedded system, embedded microcontroller. It became a best-selling CPU in that segment, along with the competing AMD 29000. In spite of its success, Intel stopped marketing the i960 in the late 1990s, as a result of a settlement with Digital Equipment Corporation, DEC whereby Intel received the rights to produce the StrongARM CPU. The processor continues to be used for a few military applications. Origin The i960 design was begun in response to the failure of Intel's Intel iAPX 432, iAPX 432 design of the early 1980s. The iAPX 432 was intended to directly support high-level languages that supported tagged architecture, tagged, memory protection, protected, garbage collection (computer science), garbage-collected memory—such as Ada (programming language), Ada and Lisp (programming language), Lisp—in hardware. Because of its instruction-set complexity, its multi- ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Channel I/O
In computing, channel I/O is a high-performance input/output (I/O) architecture that is implemented in various forms on a number of computer architectures, especially on mainframe computers. In the past, channels were generally implemented with custom devices, variously named channel, I/O processor, I/O controller, I/O synchronizer, or '' DMA controller''. Overview Many I/O tasks can be complex and require logic to be applied to the data to convert formats and other similar duties. In these situations, the simplest solution is to ask the CPU to handle the logic, but because I/O devices are relatively slow, a CPU could waste time waiting for the data from the device. This situation is called 'I/O bound'. Channel architecture avoids this problem by processing some or all of the I/O task without the aid of the CPU by offloading the work to dedicated logic. Channels are logically self-contained, with sufficient logic and working storage to handle I/O tasks. Some are powerful or fle ...

Special Interest Group
A special interest group (SIG) is a community within a larger organization with a shared interest in advancing a specific area of knowledge, learning or technology where members cooperate to effect or to produce solutions within their particular field, and may communicate, meet, and organize conferences. The term was used in 1961 by the Association for Computing Machinery (ACM), an academic and professional computer society. SIG was later popularized on CompuServe, an early online service provider, where SIGs were a section of the service devoted to particular interests. Technical SIGs The ACM includes many SIGs, some starting as smaller "Special Interest Committees" and formed the first group in 1961. ACM supports further subdivision within SIGs for more impromptu informal discussion groups at conferences which are called Birds of a Feather (BoF). ACM's Special Interest Groups (SIGs) represent major areas of computing, addressing the interests of technical communities that dri ...

Windows (operating System)
Windows is a Product lining, product line of Proprietary software, proprietary graphical user interface, graphical operating systems developed and marketed by Microsoft. It is grouped into families and subfamilies that cater to particular sectors of the computing industry – Windows (unqualified) for a consumer or corporate workstation, Windows Server for a Server (computing), server and Windows IoT for an embedded system. Windows is sold as either a consumer retail product or licensed to Original equipment manufacturer, third-party hardware manufacturers who sell products Software bundles, bundled with Windows. The first version of Windows, Windows 1.0, was released on November 20, 1985, as a graphical operating system shell for MS-DOS in response to the growing interest in graphical user interfaces (GUIs). The name "Windows" is a reference to the windowing system in GUIs. The 1990 release of Windows 3.0 catapulted its market success and led to various other product families ...

NetWare
NetWare is a discontinued computer network operating system developed by Novell, Inc. It initially used cooperative multitasking to run various services on a personal computer, using the IPX network protocol. The final update release was version 6.5SP8 in May 2009, and it has since been replaced by Open Enterprise Server. The original NetWare product in 1983 supported clients running both CP/M and MS-DOS, ran over a proprietary star network topology and was based on a Novell-built file server using the Motorola 68000 processor. The company soon moved away from building its own hardware, and NetWare became hardware-independent, running on any suitable Intel-based IBM PC compatible system, and able to utilize a wide range of network cards. From the beginning NetWare implemented a number of features inspired by mainframe and minicomputer systems that were not available in its competitors' products. In 1991, Novell introduced cheaper peer-to-peer networking products for DOS a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
