- In computing, an
opcode (abbreviated from
operation code) is an
enumerated value that
specifies the
operation to be performed.

- An
opcode table (also
called an
opcode matrix) is a
visual representation of all
opcodes in an
instruction set. It is
arranged such that each axis of...

illegal opcodes, on many processors, is just a trap to an
error handler. However, some
processors that trap for most
illegal opcodes do not do so...
- ****embly,
numerical opcodes and
operands are
replaced with
mnemonics and labels. For example, the x86
architecture has
available the 0x90
opcode; it is represented...
