Systems and methods for tracking data cache miss requests with data cache tags

Abstract

The disclosed computer-implemented method for tracking miss requests using data cache tags can include generating a data cache miss request associated with data requested in connection with a cacheline and allocating a miss address buffer entry for the miss request. Additionally, the method can include, setting a fill-pending flag associated with the cacheline in response to the data associated with the data cache miss request being absent from a first data cache, and de-allocating the miss address buffer entry. In the event that another load or store operation requests the same data associated with the cacheline while the fill-pending flag is set, the method can include monitoring for a fill response associated with the miss request until the fill response is received. Upon receipt of the fill response, the method can include re-setting the fill-pending flag associated with the cacheline.
