This abstract first appeared for US patent application 18913223 titled 'PROCESSOR IDENTIFICATION

Original Abstract Submitted

The present description concerns a device comprising a bus, peripherals coupled to the bus, the peripherals comprising a first circuit, processors coupled to the bus and initiating accesses to the peripherals, each comprising an address phase followed by a data phase, and for each processor, a second circuit delivering an identifier of the processor over the bus during the address phase of each access initiated by the processor. For each read access to the first circuit initiated by one of the processors, the first circuit stores the identifier present over the bus during the address phase of the access, and then delivers the identifier stored over the bus during the data phase of the access.
