Abstract

A data processing system includes a plurality of coherent masters, a plurality of coherent slaves, and a coherent data fabric. The coherent data fabric has upstream ports coupled to the plurality of coherent masters and downstream ports coupled to the plurality of coherent slaves for selectively routing accesses therebetween. The coherent data fabric includes a probe filter and a directory cleaner. The probe filter is associated with at least one of the downstream ports and has a plurality of entries that store information about each entry. The directory cleaner periodically scans the probe filter and selectively removes a first entry from the probe filter after the first entry is scanned.
