Aabrash with related products. People who actually buy software, on the other hand, care only about how well that software performs, not how it was developed nor how it is maintained.

The scene is Buffalo, New York, in the dead of winter, with the snow piled several feet deep. Douglas Sherk rated it really liked it May 25, Never underestimate the importance of the flexible mind.

VGA Data Machinery 2. Let me put it this way: Nick Loadholtes rated it it was amazing Nov 19, You could add the two registers together to address memory, like this:. First, consider the series of MUL instructions in Listing 4. Just why is Listing 1.

There is only one way to discover just how significant the impact of the display adapter cycle-eater is for any particular graphics code, and that is abradh course to measure the performance of that code. In short, Listing 1. Programming is not a zero-sum game. For instance, the instructions.

On the other hand, it is by no means essential that you understand exactly how the Zen timer works. In order to think differently from a compiler, you must understand both what compilers and C programmers tend to do and how that differs from what assembly language does well.


Where we want to search a fixed-length buffer for the first occurrence of a string, strstr searches a string for the first occurrence of another string. Michael wrote an article about quake once that described the inner loop optimization of the software renderer.

While it is true that good assembly code is better than good compiled code, it is also true that bad assembly code is often much worse than bad compiled code; since the assembly programmer has so much control over the program, he or she has virtually unlimited opportunities to waste cycles and bytes.

The book is still very relevant to the Embedded community, embedded processors are becoming increasingly capable and are similar in many ways to the early PC’s, with simple graphics controllers and other components, and the skills to make high performance use of these can be re-learned from this book.

Psykotron rated it really liked it Dec 22, His Graphics Programming Black Book is similarly great, and covers topics so general and abrasn ranging that the title becomes a bit of a misnomer.

Along the same line, the display adapter cycle-eater makes the popular exclusive-OR animation technique, which requires paired reads and writes of display memory, less-than-ideal for the PC. One-tenth of a second! The gist of all this is simply that good assembly programming is done in the context of a solid overall framework unique to each agrash, and the flexible mind is the key to creating that framework and holding it together.

The last few chapters of this book are more relevant, and include a series bolk explorations of some of the technology behind the popular Doom and Quake 3-D games by id Corporation where the author worked. How can this be?

While this program is similar to Listing 3. I was in territory that I new almost nothing about, so I vlack everything that I could get my hands on. One effective technique is to minimize access to memory operands, since such accesses compete with instruction fetching for precious memory accesses. The key difference between the long-period Zen timer and the precision Zen timer is that the long-period timer leaves interrupts enabled during the timing period.

Believe it or not, a single REP MOVSW instruction can lose as much asword-sized memory accesses x 4 cycles, orcycles to the 8-bit bus cycle-eater! It turns out that the CPU has to do a lot of waiting, for three reasons. When I wrote video games for a living, I spent days at a time trying to wring more performance from booj graphics drivers.

However, using the registers is a rule of thumb, not a commandment. Over the two years I worked at id, I wrote a number of columns about Quake in Dr. Some time boko, I was asked to work over a critical assembly subroutine in order to make it run as fast as possible. Page 1 of 1 Start over Page 1 of 1. As a result, timer interrupts are recognized by the PC, arbash the BIOS to maintain an accurate system clock time over the timing period.

If I’m starting now, why wouldn’t I want to target it? Note that the command can take as much as 10 minutes to finish on a slow PC if you are using MASM, with most of that time spent assembling Listing 3.

In other words, the programming interface is 16 bits wide, but the hardware interface is only 8 bits wide, as shown in Figure 4.
