INTEL INTRODUCES NEW CHIPSET FOR INTEL PENTIUM III PROCESSOR-BASED PERFORMANCE PCs.Intel Corp. introduced a new chipset A group of chips designed to work as a unit to perform a function. For example, a modem chipset contains all the primary circuits for transmitting and receiving. A PC chipset provides the electronic interfaces between all subsystems (see PC chipset for illustration). for Intel Pentium III processor-based PCs targeted at the performance desktop market segment. The Intel 820E Chipset features a new I/O Controller Hub (ICH2 ICH2 - I/O Controller Hub (Intel chipset)) for greater system performance and flexibility. The Intel 820E Chipset uses the same RDRAM Memory Controller Hub (MCH MCH - Machine Check Handler MCH - Malicious Call Hold MCH - Marlette Community Hospital (Michigan) MCH - Massachusetts Coalition for the Homeless MCH - Master of Surgery MCH - Maternal and Child Health MCH - Mean Cell Hemoglobin MCH - Mean Corpuscular Hemoglobin MCH - Medical Center Hospital (Odessa, TX) MCH - Memory and Command Handler MCH - Memory Channel Hub MCH - Memory Controller Hub (Intel) MCH - Methylcyclohexane) found on the original Intel 820 Chipset introduced in November, and the ICH2 provides an additional Universal Serial Bus controller, a Local Area Network (LAN) Connect Interface, dual Ultra ATA An enhanced version of the IDE interface that transfers data at 33, 66 or 100 Mbytes/sec. These enhancements are also called "Ultra DMA," "UDMA," "ATA-33," "ATA-66," "ATA-100," "DMA-33," "DMA-66" and "DMA-100." See IDE for all the ATA types and speeds./100 controllers and up to six-channel audio capabilities. "With its enhanced I/O capabilities, the Intel 820E Chipset provides greater system flexibility to computer manufacturers and integrators," says Louis Burns, vice president and general manager of Intel's Desktop Platforms Group. "And like the Intel 820 Chipset, the Intel 820E Chipset is designed to take advantage of the power in the fastest Intel Pentium III processors, providing the highest performance in video, graphics and multimedia both on and off the Internet." With two USB controllers, the ICH2 offers 24 Mbps of bandwidth across four ports, supporting Intel's push for Ease of Use of the PC. Feature integration also includes dual Ultra ATA/100 controllers to support the fastest integrated device electronics (IDE) transfer rates available and added performance using Intel's storage driver. To meet the needs for e-home use, the ICH2 has an enhanced AC'97 (Audio Codec'97) A specification for building audio and modem functions on a PC motherboard. Introduced in 1996 by Intel, AC'97 provides 20-bit, 48kHz audio with six channels (5.1). It supports one audio stream per system and a two element array microphone. Controller and Codec AC'97 is made up of a controller connected to analog/digital codecs by a 5-wire TDM interface called "AC Link. interface supporting full surround-sound for Dolby Digital audio found on DVD and simultaneously supports a soft modem Software that performs modem functions using the computer's main CPU rather than in modem hardware. Instead of using a dedicated data pump, programmable DSP chips are used. For example, the PowerPC and Intel's MMX Pentiums have instructions that allow it to perform modem functions. Many modems themselves are already built as soft modems rather than using chips hardwired to a particular modulation technique. connection. To meet the networking needs for e-home or e-Business, the ICH-2 has a LAN Connect Interface (LCI) supporting multiple network connectivity solutions. By integrating the Intel PRO/100 Fast Ethernet controller directly into the chipset, Intel makes it easier for computer manufacturers and system integrators to implement cost-effective network connections in a range of desktop systems. The controller works with one of three new physical layer components from Intel and enables three distinct solutions for computer manufacturers. These solutions include: managed 10/100Mbps Ethernet with Alert on LAN technology for business environments; basic 10/100Mbps connectivity for the value segment; and 1 Mbps home networking connectivity. These physical layer components can be placed directly on the PC motherboard or used on a new type of network adapter card See adapter and expansion board. such as the Intel PRO/100 VE Desktop Adapter, which is based on the Communications and Networking Riser (CNR) specification. The CNR card allows computer manufacturers to configure network-ready solutions for several different market segments. The new components are a part of Intel's PRO/100 family of network connectivity solutions, which include mobile, desktop and server network adapter A printed circuit board that plugs into the bus of both the client machines and servers in a network. The network adapter controls the transmission and receiving of data at the data link level (OSI layers 1 and 2). It is also commonly called a "network interface card" (NIC). A transmission medium, such as twisted pair or fiber-optic cable, connects the adapters to network hubs or switches, or in the case of a bus network, to each other. cards and LAN-on-motherboard products. All of Intel's PRO/100 Network Connections are based on a common architecture and use the Intel SingleDriver technology, allowing IT managers to use a single software driver for all their networked PCs and servers. The Intel 820E Chipset is currently available to customers and priced at $35 each in 1,000-unit quantities. |
