A 22nm IA Multi-CPU and GPU System-on-Chip

📋 论文概要

该论文介绍了代号为Ivy Bridge的22纳米多CPU与GPU系统级芯片，集成了最多四个高性能IA核心、一个优化的图形/媒体处理单元以及内存、PCIe和显示控制器。它解决了在单个芯片上实现高性能计算与图形处理集成、同时优化功耗和性能的问题。

💡 主要创新点

• 在IA核心中增加了流水线除法器和下一页预取器，提升了计算性能。
• 采用22纳米工艺，实现了约1.4亿晶体管集成在约160平方毫米的芯片面积上。
• 在功耗和性能方面引入了多项增强，相比前代产品有显著改进。

processor codenamed Ivy Bridge that integrates up to four high-performance Intel Architecture (IA) cores, a power/performance optimized graphics/media processing unit (GPU), as well as memory, PCIe, and display controllers in the same die. The Ivy Bridge architecture is derived from the second-generation Intel Core™ processor [2], seen in Fig. 3.1.1. The processor has about 1.4 billion transistors in about 160mm2 in its largest incarnation. It introduces several enhancements in power, performance, and features over its predecessor. The IA core adds a pipelined divider, a next page prefetcher, additions to the ISA for 16b floating point conversion, fast string moves, and fast access of the FS/GS base registers. The Graphics/Media
