Patent number: 11615023Abstract: A processing system has at least one internal processing unit and associated memory. The memory is accessible by at least two other independent processing units, and the memory of the at least one internal processing unit includes a data structure shared by the at least two other independent processing units that are allowed to perform direct memory writes into the shared data structure. A dedicated set of one or more bits in the shared data structure is allocated to each one of the at least two other independent processing units, each bit or each group of bits in the shared data structure indicates a unique combination of independent processing unit and application handler for handling an application in relation to the corresponding independent processing unit.
