ABSTRACT OF THE DISCLOSURE An interrupt handling apparatus for a data proces- sing system comprises a plurality of processing units and a working memory which the units may access through a common bus by means of multilevel interrupt or access requests. Access requests are forwarded by each unit to a bus access controller preferably made part of the working memory through a single lead for each unit, irrespective of the access re- quest level, and if the priority level of an access request is high a high level access request signal is distributed by the high level interrupting unit to the other system units, which are responsive to such signal and mask any possible access request of a lower level. The bus access controller grants access to one unit at a time on a priority basis determined by a priority network in the controller totally insensitive to any level difference of the access requests.
