Abstract: The present application describes embodiments of techniques for picking a data array lookup request for execution in a data array pipeline a variable number of cycles behind a corresponding tag array lookup request that is concurrently executing in a tag array pipeline. Some embodiments of a method for picking the data array lookup request include picking the data array lookup request for execution in a data array pipeline of a cache concurrently with execution of a tag array lookup request in a tag array pipeline of the cache. The data array lookup request is picked for execution in response to resources of the data array pipeline becoming available after picking the tag array lookup request for execution. Some embodiments of the method may be implemented in a cache.

Abstract translation: 本申请描述了用于在数据阵列流水线中选择用于执行数据阵列查找请求的技术的实施例，该数据阵列查找请求在标签阵列管线中同时执行的对应的标签数组查找请求后面的可变数量的循环。 用于选择数据阵列查找请求的方法的一些实施例包括在高速缓存的标签阵列管线中执行标签阵列查找请求的同时，在高速缓存的数据阵列流水线中选择用于执行的数据阵列查找请求。 选择数据数组查找请求以在执行标签数组查找请求之后响应于数据数组流水线变得可用的资源进行执行。 该方法的一些实施例可以在高速缓存中实现。
