assembly - Are Instruction set architecture binary (not readable) or human-readable? -


  1. if correct, isa set of instructions in machine language. instructions in isa 0/1 binary sequences?

  2. why did see instructions in isa human-readable words in books?

    are human-readable words represent instructions in isa same mnemonics used in assembly language of isa?

    are human-readable words of instructions in isa part of isa?

    if yes, there translation process translate human readable instructions in isa machine language, assembler translates assembly language machine language?

thanks.

the isa defines @ least name of instruction , binary encoding of instructions , operands. may define assembler syntax / semantic use, is, human-readable form.

but, actual compiler can use different syntax. example: ia32 isa (x86), there intel , at&t assembler style. both differ in whether result register specified first or last operand in assembler instruction.
