Abstract

The Sparc T4 is the next generation of Oracle's multicore, multithreaded 64-bit Sparc server processor. It delivers significant performance improvements over its predecessor, the Sparc T3 processor. The authors describe Sparc T4's key features and detail the microarchitecture of the dynamically threaded S3 processor core, which is implemented on Sparc T4.
