Abstract: A communication system and method of communicating including a slave function connected to a master function by a single address bus, a write data bus and a read data bus so as to allow for overlapping multiple cycle read and write operations between the master function and the slave function. Preferably the communication system includes a plurality of slave functions connected to a master function by the single address bus, the write data bus and the read data bus. A plurality of master functions may be connected to the slave functions through a bus arbiter connected to the plurality of master functions by an address bus, a write data bus and a read data bus for each master function. The bus arbiter receives requests for communication operations from the plurality of master functions and selectively transmits the communication operations to the slave functions.
