摘要: An enhanced interrupt controller is provided which able to receive both hardware-generated and software-generated request signals. Data associated with each received or signal stored in a storage unit within the an order depends on priority level of data and, for same priority, chronological receipt. The instructs processor, it communication, read from ensuring that higher before lower priority. A method routing signals processor also disclosed.
