摘要

本文介绍了一种采用65nm 8金属层工艺实现的95w双核64位Xeonreg MP处理器。每个处理器核心都有一个统一的1MB二级缓存,并支持intel扩展内存64技术和超线程技术。共享L3缓存具有广泛的RAS功能,包括Intelreg缓存安全技术和纠错码(ECC)。该处理器经过设计和优化,可在目标产品频率下以95W热设计功率包络运行。前端总线运行速度为667 MT/s或800 MT/s,采用3负载拓扑结构,与现有平台兼容。

A 65nm 95W Dual-Core Multi-Threaded Xeon® Processor with L3 Cache
This paper describes a 95 W dual-core 64-bit Xeonreg MP processor implemented in a 65 nm 8 metal layer process. Each processor core has a unified 1MB L2 cache and supports the Intelreg Extended Memory 64 Technology and the Hyper-Threading Technology. The shared L3 cache has extensive RAS features including the Intelreg Cache Safe Technology and Error Correction Codes (ECC). The processor is designed and optimized to operate at a 95W thermal design power envelope at the target product frequency. The front-side bus operates at 667 MT/s or 800 MT/s in a 3 load topology that is compatible with existing platforms.
