Abstract
A data communication arrangement permits efficient data transfer between a controller module and multiple target modules using a two-phase protocol. The controller module and the target modules can each reside in separate clock domains. Consistent with one example embodiment, a data communication arrangement includes a plurality of target modules, and a first XOR tree arranged to provide a first data integrity-indicating signal and to respond to a respective second data integrity-indicating signal from each of the target modules. A second XOR tree is arranged to provide a first data bus and to respond to a respective second data bus from each of the target modules. Also, a controller module is used to determine availability of data on the first data bus in response to the first data integrity-indicating signal.
