A comparison of RISC architectures

摘要

Three new RISC (reduced instruction set computer) architectures, the Intel i860, the Motorola 88000, and the Sun Microsystems Sparc, are compared. The relative importance of an architectural comparison, as opposed to a comparison of implementations, is discussed, followed by a high-level overview of each of the architectures. The relative strengths and weaknesses of the three architectures in a number of key areas are analyzed, and their overall relative strengths and weaknesses are summarized.
