New CISC architecture takes on RISC

摘要

A recent study in the ACM Transactions on Computer Systems came to the conclusion that processor instruction set architectures, whether reduced (RISC) or complex (CISC), are irrelevant to basic power and performance in today's designs, particularly in relation to either the Arm or Intel processors. However, there may be reasons to believe that a new CISC ISA, created for modern compilers without the limitations of compatibility with low-level legacy code, could be more effective.
