It seemed like the whole world was watching, waiting to see if id Software could top Doom; every casual e-mail tidbit or conversation with a visitor ended up posted on the Internet within hours. Nearly all literature on assembly programming discusses only the programming interface: So we know we want to work with a large buffer, filling it as infrequently as possible.

It wasn’t, however, fast enough for me. On bllack other hand, optimal code is an elusive thing indeed; by no means should you assume that the code in this book is ideal! PCs can work wonders. Wait states are nothing more or less than wasted time as far as the CPU and your program are concerned.

Calls and returns are slow, especially in the large code model, and the pushes required to put parameters on the stack are expensive as well.

The truth of the matter is that the is a bit processor that often performs like an 8-bit processor. Invoking memcmp for each potential match location works, but entails considerable overhead.

Get fast, free shipping with Amazon Prime. Fans of other bit processors call the an 8-bit processor. After all, the performs byte-sized memory accesses just as quickly as the Speeding Up C with Assembly Language 3. If you wish to time code directly in place in your programs, rather than in the test-bed program of Listing 3.

His complete works are contained in this massive volume, including everything he boook written about performance coding and real-time graphics. Amazon Drive Cloud storage from Amazon.

I only follow the Kronos group antics as a spectator, so I might be completely wrong but it seems the 4. However, as we just learned, the actual performance of any instruction depends on the code mix preceding any given use of that instruction, which in turn affects the state of the prefetch queue when the instruction starts executing.

Who on Nov 2, One point of interest is that ZTimerOn disables interrupts.

There Ain’t No Such Thing as the Fastest Code

It was published as a challenge in his “Pushing the Envelope” column: Once he opened up the possibility that abbrash were faster approaches, and looked beyond the specific approach that he had so carefully optimized, he was able to come up with code that was a lot faster.

Wu’ed in Haste; Fried, Stewed at Leisure 1. The initial count is again counted down two at a time, and the output state is toggled back when the count reaches zero.

Douglas Sherk rated it really liked it May 25, Never underestimate the importance of the flexible mind. I learned the dark secrets of the EGA video controller there, and developed a few neat tricks of my own.

If a disk cache is enabled and the file to be checksummed is already in the cache, the assembly version is three times as fast as the C version.

Joe Drago rated it it was amazing Mar 12, When the topic of optimizing came up in blwck of the BIX conferences, Terje’s program was mentioned, and he posted the following message: Downloaded from a BBS, learned the basics of graphics programming As a result, the time per instruction of Listing 4. All this is basically a way of saying: This is the right way of doing things — like converting your crucial glack to assembly language after doing all your development in C.

Not so long ago, Terje Mathisen, who I introduced earlier in this book, wrote a very fast word-counting program, and posted abraash on BIX. As I was writing my last game, I discovered that the program ran perceptibly faster if I used look-up tables instead of shifts and adds for my calculations.

The display adapter cycleis another possible culprit, and, on s and later processors, cache misses and pipeline execution hazards produce this sort of effect booo well.
