Extractions: Longtime PC users know better than to get too attached to their systems. Before you realize it, the technology in your desktop is outdated and too slow for the latest and greatest components and applications. Worse yet, some technologies simply fade away, making peripheral upgrades impossiblelook at what happened to ISA and VL-bus expansion slots. Well, get ready for not one, not two, but three new technologies for desktops that will render your current PC obsolete. The first of the new technologies that you are likely to see is AGP 8X, the final speed step for the accelerated graphics port before it too starts fading away in 2004 (see PCI Express below). A single expansion slot on a system motherboard, AGP provides a fast and direct connection between a graphics card and system memory. AGP 8X supports a potential throughput of more than 2.1GB per secondtwice the speed of today's AGP 4X solutions.

Extractions: Return to June 8, 1998 table of contents The BUSiness Report Ray Alderman I n 1993, Andy Grove of Intel set the world straight when he introduced PCI as a local bus for PC peripheral interfaces. In those days, it took an engineer four months or more to design a new motherboard for the latest Intel CPU chip, and Andy's problem was time-to-volume. When PCI standardized the I/O bus, the design time dropped to a few months. Anyone who could read the pin-out could design the I/O subsystem for a PC. Intel then standardized the memory architecture and the pin-out for the single-edge cartridge connector on the Pentium II modules (SECC). They also tightly controlled the chip-set specifications. Today, a motherboard can be designed in six weeks or less with these parts. The engineer only connects the CPU cartridge to the PCI local bus and the memory modules on the motherboard. These innovations solved the time-to-volume problems temporarily, but the solution was only stop-gap. Now the PC market is slowing, and growth is in the convergence market of digital TVs, "entertainment PCs," and Internet appliances. But the present PC architecture is too expensive, and PCI is too slow for this new market segment. Then there's Microsoft Corp.the biggest impediment to cracking this consumer market.

Extractions: Christopher B. Browne's Home Page cbbrowne@acm.org Christopher Browne's Web Pages Prev Next I2O Sig is a group responsible for upcoming ``standards'' for an I/O bus that runs in a highly buffered fashion, somewhat independently from the main ``system'' bus. This approach replicates what mainframe systems have long done, offloading as much I/O work as possible onto independent processors that manage the individual devices so that the main processor need not manage this. While the general idea is very good, the standards have been highly encumbered by NDAs (Non Disclosure Agreements) which hinders usage in conjunction with Linux. See the I2OBus article from WIRED. It is possible that the problems may relate to the use of patented technologies, which means that the nondisclosure may not be by choice of the I2O group, but rather has been forced on them. In any case, this is not likely to be a technology that will substantially affect home users' systems. It will not scare off ``serious'' users that are willing to spend $15,000 on a RAID disk array, but if you are one of those that is happy with a $200 IDE drive, I2O is definitely not for you. Instead of paying $200 for a disk drive, you'll pay $800 for a ``disk subsystem,'' because there will be a need to add I2O controllers and other associated hardware. There's also a linux-i2o@dpt.com

Extractions: Serial buses dot the landscape of embedded design. From displays to storage to peripherals, serial interfaces make communications possible. Many serial communication interfaces compete for use in embedded systems. The right serial interface for your system depends on several key factors. In this article I will describe seven of the most common serial interfaces, to help you decide which bus is right for your next project. Why serial?

It does not look very much like the SCSI we know, but is a further development being a serial high speed bus. It also a bit like USB in terms of hot-plugging and simple connections. The interface IEEE1394 has a bandwidth of 400 Mbit per second, which is a lot better than USB and comparable to SCSI. FireWire handles up to 63 units on the same bus. The units can be plugged and unplugged hot - meaning you do not have to power down the PC. The Firewire was expected to replace: Parallel Centronics port (to some extent) IDE SCSI EIDE (later on) However, Firewire so far has not become the real big thing for PCs. People with Macintosh computers soon found great use for FireWire, especially to connect high performance flatbed scanners. Today Firewire is supported by Windows XP and it is gaining momentum. Among others it is used for: Connecting DV-cameras to video editing adapters High-end scanners Hot-plugged external harddisks from Maxtor with FireWire interface.
Extractions: As microprocessors continue to push the limits of performance, buses are bumping up against the laws of physics in their attempt to keep pace. The large voltage swings required for parallel buses limit their achievable peak clock rate, and ratcheting up bandwidth to increase the bus width is impractical because of pin-count and signal-skew issues. Parallel buses have been evolving for a long time, but they are running out of steam. Serial interconnects will provide the quantum leap in performance and capability that will complement today's processor performance and enable exciting new applications. The interconnect solution for high-performance digital signal processors (DSP) is coming from the telecommunications industry. By using lower voltage swings and differential signaling (LVDS), it's possible to produce very high data rates using a serial connection. Whereas a parallel bus may require 64 data lines plus some parity and control lines, and a clock rate of 133 MHz (PCI-X) to get a half-duplex bandwidth of 1 Gbyte/second, components are becoming available that can provide 250 Mbytes/s bandwidth full-duplex. This delivers an effective bandwidth of 0.5 Gbytes/s over four wires using LVDS serial technology clocked at 2.5 GHz.

Extractions: "This standard defines an integrated interface between devices and host processors. It provides a common point of attachment for systems manufacturers, system integrators, and suppliers of intelligent devices."... The ATA interface is the commonly used interface for attaching IDE hard disks and ATAPI CD-ROM drives. ATA-2 FAQ - by Peter Herweijer "The purpose of this document is to provide a technical specification of a high-speed serialized ATA data link interface." Serial ATA is defined with the following goals and requirements listed in no particular order: Primary inside-the-box storage connection, completely compatible with ATA, low pin count for both host and devices, low voltage, supports lower cost device architectures, higher performance than equivalent ATA. Small Computer System Interface - v2 (SCSI-2) "This standard defines mechanical, electrical, and functional requirements for attaching physically small computers with each other and with intelligent peripherals such as rigid disks, flexible disks, magnetic tape devices, printers, optical disks, and scanners. The resulting interface facilitates the interconnection of physically small computers and intelligent peripherals and thus provides a common interface specification for both systems integrators and suppliers of intelligent peripherals."
