Zusammenfassung:A memory access method is employed in a multiprocessor system which includes a plurality of system modules coupled via a crossbar module, where each of the system modules includes a buffer which holds data and a plurality of processors having a cache memory which temporarily holds data. The memory access method includes a step, responsive to a read request from a processor within an arbitrary system module, holding data preread from a system module other than the arbitrary system module in a buffer within the crossbar module.
