20120191891 | MULTI-MASTER BUS ARBITRATION AND RESOURCE CONTROL - The present invention discloses an arbitration mechanism for controlling access of a plurality of nodes external to a shared resource, to which accesses by the number of nodes must he restricted, is applicable to any shared source in a computer or computer-controlled system. The present design delivers the following advantageous features. It provides localized arbitration to obtain resource access and localized self-management of resource mastery; eliminates resource seizure locally; it allows equal access to the share resource, encapsulate all four above features with the same circuit/protocol. | 07-26-2012 |
