UNIT 21
Hardware Solution Vs. Software Solution 1A huge hardware jock always claims, “Anything you can do in software, I can do cheaper and faster in hardware.” Of course, he is always stumped when he is asked to make a quick feature change and recompile his hardware. But the battle between the flexibility of software vs. the speed of hardware is as old as the computer industry itself.
But even without a new OS, these features can be utilized. 6Leveraging Windows’ drivers model, specialty vendors will offer drivers that can fully exploit those integrated features. Thus providing dramatically improved-or arguably, finally usablevideo and speech capabilities. Of course, this
UNIT 21
The Pentium Ⅲ epitomizes this shift. 5Buried into this chip are 70 new instructions that will greatly improve the performances of demanded features, such as speech input and video output. However, with some of the cutbacks in Windows 2000, it could be one to three years before the native OS can leverage these integrated features.

4But as the corporate computing industry has matured, the situation has radically shifted. Software solutions have become more bloated in an attempt to cram myriad features into a more complicated OS. This feature cram has increasingly delayed the next generation of the operating system.
UNIT 21
This race started in 1981 when MS-DOS used several software “trickery” to fake the hardware into exploiting certain features. 3These were important tricks needed to increase the speed of slow hard drivers, or to address more RAM than the processor was designed to access. But the secret of success for these solutions was the capability of Microsoft and other vendors to quickly develop software solutions. Software solutions always ran slower than their hardware counterparts, but were often cwk.baidu.commpleted years before hardware vendors could deliver their offering.
At the same time, hardware vendors such as Intel have gotten more sophisticated in their processor development. Given their clockwork like development of next generation processors, vendors are now able to offer solutions that are just appearing on the agenda of many computer user.
UNIT 21
2Given the relative quickness of software developments, one would think that software solutions would lead the computing agenda for many years. But as software delays have become more profound and commonplace, hardware-featured solutions are beginning to offer better solutions than their software counterparts. And given the improving capabilities of hardware vendors will become the clear leader in this race.
