针对众核CPU芯片中缓存一致性片上网络(Network-on-Chip,NoC)缓存一致性监听及监听响应过程耗时过长的问题,提出多播和自适应路由两种技术来加速该过程。根据这两种技术的需求,设计了片上网络监听请求、监听响应数据包格式,并进一步设...针对众核CPU芯片中缓存一致性片上网络(Network-on-Chip,NoC)缓存一致性监听及监听响应过程耗时过长的问题,提出多播和自适应路由两种技术来加速该过程。根据这两种技术的需求,设计了片上网络监听请求、监听响应数据包格式,并进一步设计实现了监听请求通道和监听响应通道的NoC路由器和8×8网络。设计实践表明,按照文中所提的NoC路由器在22 nm工艺下大小为85940.3μm 2或103518.5μm 2,8×8的监听请求及监听响应网络大小为5.57 mm 2,复杂度可接受。通过仿真实验比较了单播和多播、确定性路由和自适应路由4种配置下监听及监听响应过程的耗时。结果表明,在监听请求消息需要监听全部252个处理器核心时,所提技术可使1个监听请求消息的监听及监听响应过程耗时减少45%,且远小于DDR/HBM的访问延迟。若进一步在一致性节点(Point of Coherency,PoC)处采用Outstanding技术,所提技术可使32个监听请求消息的监听及监听响应过程耗时减少73%。仿真结果证实了所提多播和自适应路由技术的有效性。展开更多
