Systems, apparatuses, and methods for scheduling metadata requests

The invention discloses a system, a device and a method for scheduling metadata requests. In one embodiment, an apparatus includes a memory and a scheduler. The scheduler is coupled to the memory and the memory controller. The memory stores a plurality of metadata requests. Each of the plurality of metadata requests is associated with one of the plurality of metadata priority levels. The scheduler schedules transfer of a first metadata request of the plurality of metadata requests to the memory controller based at least in part on a first metadata priority level associated with the first metadata request and a first bandwidth portion of the metadata bandwidth. The first bandwidth portion is associated with a first metadata priority level. Other embodiments are described and claimed. 本申请公开了用于调度元数据请求的系统、装置和方法。在一个实施例中，一种装置包括存储器和调度器。调度器耦合至存储器和存储器控制器。存储器存储多个元数据请求。多个元数据请求中的每个元数据请求与多个元数据优先级级别中的一个元数据优先级级别相关联。调度器至少部分地基于与多个元数据请求中的第一元数据请求相关联的第一元数据优先级级别、以及元数据带宽的第一带宽部分来调度第一元数据请求到存储器控制器的传送。第一带宽部分与第一元数据优先级级别相关联。描述并要求保护其他实施例
