  • Mechanism for granting controlled access to a shared resource
    Patent number: 8576236
    Abstract: Disclosed are methods and systems for granting an application-specific integrated circuit (ASIC) in a multi-ASIC environment controlled access to a shared resource. A system includes a first ASIC, a second ASIC, and a shared memory that stores a shared resource and a data set partitioned into fields. The first ASIC writes data to a first subset of the fields and reads data from the fields. The first ASIC includes first logic that computes a first value based on the data read from the fields. The second ASIC writes data to a second subset of the fields and reads data from the fields. The second ASIC includes second logic that computes a second value based on the data read from the fields. Based on the first and second values respectively computed by the first and second logic, only one of the first and second ASICs gains access to the shared resource.
