A tagged cache is disclosed for data coherency in multi-domain debug operations. Access requests to a memory within a target device are received for data views associated with debug operations, and access requests include virtual addresses associated with virtual address spaces and client identifiers associated with requesting data views. Virtual addresses are translated to physical addresses within a tagged cache using address translation tables that associate virtual addresses from the different virtual address spaces with client identifiers and with physical addresses within the cache. Data within the cache is cached using the physical addresses. Further, when data is written to the cache, virtual address tags within the cache are used to identify if other virtual addresses are associated with the physical address for the write access request. If so, client identifiers stored within the address translation tables are used to notify affected data views of changed data.
