The Motorola 88110 Superscalar RISC microprocessor

The Motorola 88110 is a second-generation, single-chip RISC (reduced instruction set computer) microprocessor that uses advanced techniques for exploiting instruction-level parallelism. Superscalar instruction issue, speculative execution, limited dynamic instruction recording and multiple on-chip caches are used to achieve high performance at a cost that makes it ideally suited as a central processor in low-cost personal computers and workstations. The advanced superscalar processor architecture and a high level of circuit integration have been implemented in a high-yield, triple-level metal, CMOS process using 1 mu design rules and requiring under 1.3 million transistors.<>
