  • Method of and circuitry for controlling access by a master to a peripheral, a method of configuring such circuitry, and associated computer program products
    Patent number: 9946669
    Abstract: A method of controlling access by a master to a peripheral includes receiving an interrupt priority level from an interrupt controller associated with the peripheral, comparing the interrupt priority level with respective a pre-established interrupt access level to obtain an interrupt level comparison result, establishing whether an access condition is satisfied in dependence on the interrupt level comparison result, and if the access condition is satisfied, granting access. If the access condition is not satisfied, access is denied. Further, a circuitry is described including a master, a peripheral, and an access control circuitry including an interrupt controller associated with the peripheral. The access control circuitry is arranged to perform a method of controlling access by the master to the peripheral.

  • A METHOD OF AND CIRCUITRY FOR CONTROLLING ACCESS BY A MASTER TO A PERIPHERAL, A METHOD OF CONFIGURING SUCH CIRCUITRY, AND ASSOCIATED COMPUTER PROGRAM PRODUCTS
    Publication number: 20150378944
    Abstract: A method of controlling access by a master to a peripheral includes receiving one or more interrupt priority levels from one or more interrupt controllers associated with the peripheral, comparing the one or more interrupt priority level with respective one or more pre-established interrupt access levels to obtain an interrupt level comparison result, establishing whether an access condition is satisfied in dependence on at least the interrupt level comparison result, and if the access condition is satisfied, granting access. If the access condition is not satisfied, access is denied. Further, a circuitry is described including one or more masters, one or more peripherals, and an access control circuitry including one or more interrupt controllers associated with the one or more peripherals. The access control circuitry is arranged to perform a method of controlling access by a master of the one or more masters to a peripheral of the one or more peripherals.
