Abstract :
A fifth generation SPARC64 processor implemented in 130 nm CMOS process with 8 layers of Cu metallization operates with a 1.3 GHz clock and dissipates 34.7 W. The processor is a 4-issue out-of-order design with 2 MB on-chip level-2 cache. Error checking is added on the data-path in addition to memory. An instruction is retried for correction when an error is detected in the datapath.
