As the newest member of the 68000 microprocessor family, the MC68060 microprocessor offers a cost-effective, power-thrifty solution for high-performance embedded processing applications. This article focuses on its microarchitectural features, such as superscalar pipeline implementation, that enable it to achieve its high-performance objectives while maintaining 68000 user-code compatability. Running at 50 and 66 MHz, the first 3.3V implementations achieve 103 Dhrystone MIPS performance at 66 MHz.>
