ABSTRACT:
Described are a system and method for broadcasting write requests to a plurality of graphics devices. A different address range of graphics device addresses is associated with each graphics device of the plurality of graphics devices. A controller receives a write request directed to a memory address and generates a plurality of graphics device addresses based on the memory address of the write request when the memory address is within a particular range of broadcast addresses. An offset may be applied to a reference address in each address range associated with one of the graphics devices when generating the plurality of graphics device addresses. The write request is forwarded to each graphics device of the plurality of graphics devices associated with one of the generated graphics device addresses.
