Sieve of Eratosthenes


TODO: hay un bug en el codigo, probar lo nuevo en cc65.. la version de action ta mala :(

ADVAN COMPILER BASIC

Advan BASIC is filled with shortcuts like this. By the way, it ran my version of the Sieve of Eratosthenes in 13.8 seconds. The MMG compiler took 9 seconds, BASIC XL took 67 seconds and Atari BASIC hasn't finished yet. If that isn't fast enough, you can rewrite key routines in assembly language from within BASIC. Advan BASIC recognizes assembler mnemonics almost as if they were BASIC keywords. Not only is this great for people who know assembly language, but it can be a teriffic learning environment too.

ADVAN OPTIMIZER

Advan BASIC was already pretty fast. Now it's the fastest BASIC in Atari history. In our Sieve Benchmark, the Advan Optimizing Compiler is about four times faster than the MMG Compiler, six times faster than regular Advan, 20 times faster than compiled Turbo-BASIC XL and 120 times faster than uncompiled Atari BASIC. In fact, it's more than half the speed of ACTION!- that's getting real close to pure assembly language.

The resulting object file has a very rapid run-time. Ten iterations of the Eratosthenes Prime Number Sieve (see "First ST Performance Test," Antic, October 1985) ran in about 120 seconds with the screen on. With the screen off, the same program ran in just 80 seconds.
