Title: Bus arbitrating system

IPC: G06F13/37
Filed: 1986-05-21
Abstract: PURPOSE:To equalize priority levels of bus use of respective modules by constituting bus use permission signal lines, which connect respective modules, into a ring. CONSTITUTION:When a module a11 uses a bus, a bus arbitrating circuit 1a in the module a11 has the bus use permission right (the right by which a bus use permission signal *BG is generated). When a module c13 issues a request signal *RQ, the bus arbitrating circuit 1a receives it. The module a11 issues the bus use permission signal *BG after terminating the use of the bus, and the bus use permission signal *BG is temporarily received by a module b12 and is transferred to the module c13 as it is. Thus, the module following the module which uses the bus at present has the highest priority level of bus use and priority levels of bus use of modules are lower counterclockwise in order, and the bus use right is equally given to respective modules if operation states of all modules are averaged.
