Title: Ring arbiter circuit
Inventor: IIJIMA AKIO
IPC: G06F13/37
Filed: 1985-03-25
Abstract: PURPOSE:To reduce the increase of time needed for shift of the access right by providing the function to each of plural devices having accesses to the share resources to transmit and receive the token pulses showing the access right and connecting those devices in a ring form. CONSTITUTION:Each of devices 11-1n using in common the share resources 2 contains a ring arbiter circuit 3 and an access device 4. The arbiter 3 receives the ring arbiter output of a device 13 at the preceding stage through an input and sends the token pulse to the device at the next stage through an AND circuit 3c and an OR circuit 3e as long as the access request given from the device 4 is not latched by a holding circuit 3a when the token pulse is received. When an access request is given, the output of the circuit 3a avoids a case where the token pulse passes through the circuit 3c. Then the token pulse is produced again and sent to the next stage via a pulse detecting circuit 3b and a pulse generating circuit 3d after the access request is deleted.
