Abstract
A data processing system includes multiple processing units coupled to a system interconnect including a broadcast address interconnect and a data interconnect. The processing unit includes a processor core that executes memory access instructions and a cache memory, coupled to the processor core, which is configured to store data for access by the processor core. The processing unit is configured to broadcast, on the address interconnect, a cache-inhibited write request and write data for a destination device coupled to the system interconnect. In various embodiments, the initial cache-inhibited request and the write data can be communicated in the same or different requests on the address interconnect.
