Abstract
A system for connecting a plurality of input/output (I/O) channels to a single computer system bus. A system controller establishes priority among the I/O channels competing for access to the system bus. A plurality of I/O channel bridges are connected to the system bus and interface with EISA channels. The I/O bridges receive data from the EISA channels at one data rate and transmit the data to the system bus at another data rate. Data is stored within the I/O bridges in a cache memory device until commanded to transmit the data to the system bus by the system controller.
