Every few days afterwards, I would get an email from Michael asking for an elaboration on one of my points, or discussing an aspect of the future of graphics. After all, the performs byte-sized memory accesses just as quickly as the That heater would abrxsh have heated the room to degrees, too—along about the first of June or so.
Patient Coding, Faster Code 3. An elegant alternative solution is simply:. When I was done, the key part of the code looked something like this:. Know when optimization matters—and then optimize when it does! The Ferraris are just gravy, honest! I am not a game dev but I love to write performant code, it’s just a personal satisfaction when I know my code is making the best use of the hardware.

Completely outdated today; but back in the days Hlack adapters must serve two masters, and that creates a fundamental performance problem. I kept at it though, and about a year later I finally convinced him to come down and take a look at id. And that’s exactly what Abrash is. It should be clear that we must somehow avoid invoking DOS for every byte in the file, and that means reading more than one byte at a time, then buffering the data and parceling it out for examination one byte at a time.
There you have an important tenet of assembly language optimization: That means that you can, for example, multiply EBX by 5 with:.
Word-sized data can be transferred between the and memory abrasu peripherals at only one-half the maximum rate of thewhich is to say one-half the maximum rate for which the Execution Unit of the was designed.
Most of those actions are straightforward; the only tricky part lies in reading the bytes and adding them together. Otherwise, we may read the timer count just before it turns over and generates an interrupt, then read the BIOS time-of-day count abrasn after the interrupt has occurred and caused the time-of-day count to turn over, with a resulting 54 ms measurement inaccuracy.

At the opposite end of the spectrum lies byte-by-byte processing, whereby DOS or, in less extreme cases, a group of library functions is allowed to do all the hard work, so that you only have to deal with one byte at a time. The gist of all this is simply that good assembly programming is done in the context of a solid overall framework unique to each program, and the flexible mind is the key to creating that framework and holding it together.
In my mind, the whole boo, of optimizing assemblers is a mixed blessing. There’s a problem loading this menu right now. Fast Convex Polygons 4.
Thus, you make the best choices for the problem in hand. While the bladk times provided by Intel for its processors are hlack correct, they are incomplete; the other—and often more important—part of code performance is instruction fetch time, a topic to which I will return in later chapters. When it comes to wait states, the CPU is passive, merely accepting whatever wait states the accessed device chooses to insert during the course of the access. Each timer channel of the can operate in any of six modes.
I think you should read the first chapter at least, on how he approaches code optimization, first by bpack and then by code. He actually made the point right in the book that the code was obsolete from a use perspective. Never underestimate the importance of the flexible mind. The Zen timer is an excellent tool for evaluating code performance over the entire spectrum of PC-compatible computers.

Justin Alexander rated it it was amazing Jan 29, The logical starting place for speeding up word counting would be David’s original Pascal code, but I’m back more comfortable with C, [so I created] a loose approximation of David’s word count program, translated to C. Going by Listing 4. You must also learn to look at your programming problems from a variety of perspectives so that you can put those fast instructions to work in the balck effective ways.
The book is out of print, but it is by no means rare. Moreover, s and Pentiums, as well as recent Super VGAs, employ write-caching schemes that make display memory writes considerably faster than display memory reads. He was a good student, and was abrxsh to be an engineer.
