instruction set architecture
     
         isa the parts of a processor's design that
        need to be understood in order to write assembly language,
        such as the machine language instructions and registers.
        parts of the architecture that are left to the implementation,
        such as number of superscalar functional units, cache
        size and cycle speed, are not part of the isa.
     
        the definition of sparc, for example, carefully
        distinguishes between an implementation and a specification.
