Abstract
A processor system comprising a number of data handling units interconnected by a system bus operates according to a novel protocol wherein one of the number of data handling units issues a buss request signal together with a separate arbitration signal uniquely identifying the data handling unit requesting access to the system bus. Distributed priority determination logic, located in each data handling unit, allows each data handling unit requesting bus access at the same moment in time to independently and unilaterally ascertain who has access. The bus request signal remains asserted to hold off any additional requests for bus access until all data handling units first requesting access have been serviced.
