Semiconductor device

A semiconductor device comprising:

• a central processing unit;
• a plurality of functional blocks, each functional block configured to output an event ID based on an interrupt factor;
• and
• an event controller that outputs an event ID output instruction, which causes one or more of the functional blocks to output the corresponding event ID to others of the functional blocks,
• wherein each of the functional blocks includes:
• an interrupt factor detection unit that detects the interrupt factor, generates the event ID based on the interrupt factor, and outputs the generated event ID,
• an event ID input unit that receives an input of the event ID,
• an event response specification unit that determines whether or not the inputted event ID is one that requires response and, when the inputted event ID is one that requires response, specifies response content corresponding to the inputted event ID, and
• an event response processing unit that performs event response processing related to the specified response content without requiring the central processing unit,
• wherein the one or more functional blocks, into which the event ID output instruction is inputted, outputs the event ID to the others of the plurality of functional blocks, and
• wherein the event ID input unit of each of the others of the plurality of functional blocks receives the event ID outputted from the one or more functional blocks.
