摘要
A home node of a data processing apparatus that includes a number of devices coupled via an interconnect system is configured to provide efficient transfer of data to a first device from a second device. The home node is configured dependent upon data bus widths of the first and second devices and the data bus width of the interconnect system. Data is transferred as a cache line serialized into a number of data beats. The home node may be configured to minimize the number of data transfers on the third data bus or to minimize latency in the transfer of the critical beat of the cache line.
