ABSTRACT:
One or more common buses are provided for coupling a plurality of units in a data processing system for transfer of information therebetween. The central processing unit (CPU) allocates the one or more common buses to one of the requesting units as a function of request type and on which of one or more common buses the requesting unit is located. Bus requests are generated in a synchronous manner by use of a timing signal originating in the CPU which is connected in series between the one or more units on each of the one or more common buses.
