Abstract: A processor accumulating coherency probe responses, thereby reducing the impact of coherency messages on the bandwidth of the processor's communication fabric. A probe response accumulator is connected to a processing module of the processor, the processing module having multiple processor cores and associated caches. In response to a coherency probe, the processing module generates a different coherency probe response for each of the caches. The probe response accumulator combines the different coherency probe responses into a single coherency probe response and communicates the single coherency response over the communication fabric.

Abstract: A command replacement module at a coherency manager of a processor receives commands to be communicated over the communication fabric. For each received command of a specified type, the command replacement module compares a data payload of the command to a stored set of data patterns and, in response to a match, replaces the command with a replacement command, wherein the replacement command implies the contents of the data payload. The replacement command is communicated to the original commands destination via the communication fabric. In response to receiving the replacement command, the destination reconstructs the original command, deriving the data payload from the replacement command.
