opcode

You can make it perform better by using tricks such as output caching, recycling the compiled code that's generated at runtime (aka opcode caching) and writing extensions that are essentially bits compiled as C++.

This is done by special PHP extensions knows as opcode caching extensions.

I also ended up installing XCache for PHP opcode and var caching, along with the XCache Backend for WP.

Since sequence is important in the Avida genome – it is after all an opcode program – the probability that a given mutation will appear via insertion or substitution in a given position is then about 1/55 * 1/25, or 0.000727.

But I also use WP-Cache2, MySQL query caching, and the APC PHP opcode cache.

And the direct analogue of gene knockout also demonstrates that the opcode programs evolved in Avida are irreducibly complex, and yet they readily evolve by means of random mutations and selection.

The miniassembler allowed you to enter short machine language programs using the standard 6502 mnemonics (the three letter codes that referred to a specific type of operation; for example, "LDA #" represented the 6502 opcode $A9) instead of entering the program byte by byte in the monitor.

When a non-local label is forward referenced, the assembler assumes that it will require two bytes to represent the relative offset of the label (so the instruction including the opcode byte will be three bytes).

Generating Opcodes from General Purpose Mnemonics My A86 assembly language is modeled after Intel's ASM86 language, which uses general purpose mnemonics to represent classes of machine instructions rather than having a different mnemonic for each opcode.
