Semiconductor integrated circuit

A semiconductor integrated circuit comprising

• plural function modules performing different processes respectively,
• a thermal detecting means to put out an interrupt signal when substrate temp. exceeded reference temp.,
• a clock providing means to provide each function module with the inputted clock signal divided in a frequency division value set in a frequency division register, when the interrupt signal is not given, on the other hand, divided in an emergency frequency division value set in an emergency frequency division value register, and
• a microprocessor processing control all over the system including the plural function modules as well as processing control the frequency division vale to set according to the detecting signal of the thermal detecting means.

A semiconductor integrated circuit comprising

• plural function modules performing different processes respectively,
• a thermal detecting means to put out an interrupt signal when substrate temp. exceeded reference temp.,
• an operation controlling means to provide each module with operation controlling signal at regular interval according to a table which is compiled from the registration of operation stop order of the function module when the interrupt signal is given, and
• a clock controlling means to control output of clock signal to corresponding function module according to the operation controlling signal.

A semiconductor integrated circuit comprising

• plural function modules performing different processes respectively,
• a thermal detecting means to detect substrate temp. and compare it with reference temp. to put out detecting signal as a result of comparing,
• a clock generating means to generate a clock signal to provide function module with inputted clock signal divided in frequency division value which is increased or decreased according to the detecting signal,
• an operation controlling means to put out operation controlling signal for function module by the detecting signal according to the table which is compiled from priority of function module, and
• a clock controlling means to control output of the clock signal for function module according to the operation controlling signal.
