A Third-Generation 65nm 16-Core 32-Thread Plus 32-Scout-Thread CMT SPARC® Processor

The goals for this high-end commercial microprocessor are high throughput and high single-thread performance, mainframe-class reliability, hardware transactional memory, and linear scalability. We show how these goals are met by the logical and physical design of this 2.3GHz 396mm2 16-core 32-thread plus 32-scout-thread microprocessor.
