Abstract
A semiconductor integrated-circuit device comprises two processing subsystems, each comprising a respective processor, set of local peripherals, and bridge unit, all connected to a respective local bus. An electrical interconnect joins the respective bridge units. The first bridge unit comprises a task register, accessible over the first local bus, and can be configured to detect a write to the task register, and respond by sending an event signal over the interconnect to the second bridge unit. The second bridge unit can be configured to receive the event signal, and respond by sending an interrupt signal to the second processor.
