Abstract

PURPOSE: To reduce signal lines by dividing bus master devices into groups, executing local arbitration by a group bus arbiter for each group and afterwards executing the arbitration of a system by a system arbiter.
CONSTITUTION: Bus master devices 10-15 are divided into groups, and group arbiters 40 are provided in the respective groups. After the local arbitration is executed in the groups, the arbitration of the system is executed by a system arbiter 30. Namely, the hierarchical constitution of the arbitration is adopted. In this case, it is enough to connect the respective bus master devices 10-15 to the group bus arbiters 40. Thus, an interface signal line is shortened.
