Ibm followed this in 2003 with the 750gx , which incorporates 1mb of l2 cache at speeds of 1ghz at around seven watts of power consumption Ibm随之在2003年又发布了750gx ,它带有1mb的l2缓存,速度是1ghz ,功耗大约是7瓦。
In the memory access subsystem design , on the basis of deeply discussing three kernel problems encountered in cache design , this paper presents a li cache model with virtual index and physical tag , using a hardware - based method to solve the synonym problem , and adopting l2 cache " s initiative requesting for the li cache " s snoop service to keep the consistency between li cache and l2 cache , then takes li data cache as an example to illustrate the li cache implementation 在访存子系统的设计中,深入研究并解决了cache设计中的三个核心问题:采用虚地址索引、实地址tag ,用硬件方式解决synonym问题,以l2cache向l1cache主动请求snoop服务的方式实现两级cache间的一致性。在此基础上,给出了一个l1d - cache原型。
