RISC design, was What will Microsoft use its ARM license for?
>One of the original motivations of RISC was that a regular, orthogonal, instruction set might be easier for compilers to deal with. Now the line goes that a compiler can deal with an irregular, non-orthogonal, instruction set. It is my impression that the Berkeley RISC team was using PCC, which was by m... 10 Aug 2010 10:11
