Abstract
A data processing system and method having a number of cache controllers coupled to a bus. A cache controller uses a buffer operably coupled to the bus for loading information from the bus. A status bit associated with a buffer indicates the buffer status. The cache controller has logic circuitry operably coupled to the bus and the buffer. The logic circuitry responds to a certain cache coherency operation by loading the buffer and waiting during a predetermined interval for a possible retry signal before further processing the operation.
