I recall the satisfaction of knowing so much secret knowledge. Michael wrote an article about quake once that described the inner loop optimization of the software renderer. If not handled properly, the transformation that takes place between conception and implementation can reduce performance tremendously; for example, a programmer who implements a routine to search a list ofsorted items with a linear rather than binary search will end up with a disappointingly slow program.

Knowing that Jeff Duntemann is an aficionado pprogramming such esoterica who do you know who owns an album by The Peppermint Trolley Company? Mode X Progfamming Animation 2.

The interrupt controller is capable of remembering at most one pending timer interrupt, so all timer interrupts after the first one abraeh any given Zen timing interval are ignored.

Wait states exist because the CPU must to be able to coexist with any adapter, no matter how slow within reason. The second part covers low level graphics programming in assembly. I checked and Android 4.

Good assembly code is better than good compiled code. Wait states are well and truly the lowest level of code performance.

Create code however you want, but never forget that design matters more than detailed optimization. AmazonGlobal Ship Orders Internationally. Simple graphixs dictates that no compiler can know as much about what a piece of code needs to do or adapt as well to those needs as the person who wrote the code.

Remember, interrupts are off while the Zen timer runs, so the timer interrupt cannot be recognized until the Zen timer stops and enables interrupts. Although I was making a living at computer work and enjoying it at the time, I nonetheless harbored vague ambitions of being a science-fiction writer when I grew up.

A long-period Zen timer for use in such cases will be presented later in this chapter. Those are indeed important considerations—to persons and companies graphicss develop and distribute software.

Programking all 26 reviews. Joe Drago rated it it was amazing Mar 12, Share your thoughts with other customers. A good rough cut is a buffer that will be between 16K and 64K, depending on the exact search approach, 64K being the maximum size because near pointers make for superior performance.

That is, with a word-sized memory access, such as. ASM, enter Listing 3. Display adapters must serve two masters, and that creates a fundamental performance problem. Amazon Related Book Categories: This listing measures the time required to execute gtaphics, loads of AL from the memory variable MemVar. This chapter, adapted from my earlier book, Zen of Assembly Language located on the companion CD-ROM, goes right to the heart of my philosophy of optimization: This is just slightly longer than the time per load of AL measured by the precision Zen timer, as ;rogramming would expect given that interrupts are left enabled by the long-period Zen timer.

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!

As another example of local optimization, consider the matter of rotating or shifting a mask into position. The x86 family CPUs have a complex, irregular instruction set, and, unlike most processors, they are neither straightforward nor well-documented true code performance.

If you keep all files in the same directory, the “Previous” and “Next” links at the beginning and end of each chapter will work provided you have downloaded those chapters.

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. Organize your program so that you can do your processing within each block as fast as you could if there were only one block—which is to say at top speed—and make your blocks as large as possible in order to minimize the overhead associated with going from one block to the next.

By accessing one of the addresses every This is normally a great optimization, being both smaller and faster than a far call.
