Abstract
The disclosure provides a plurality of embodiments for controlling the bus paths for a line of data from any cache in a multiprocessing system (MP) to any requesting cache or I/O channel processor in the MP. The data transfers can occur in parallel among plural CPU caches, channel processors and main storage (MS) sections using crosspoint switches in a manner which utilizes the high circuit count of LSI modules without substantially utilizing the module I/O pin count to enable MP structures to contain more CPUs than could be contained with conventional bussing.
