  • Patent number: 7948242
    Abstract: An integrated circuit includes a monitoring-target circuit portion 1200 and a debugging circuit portion 1100. The debugging circuit portion 1100 acquires a signal on a signal line of the monitoring-target circuit portion 1200 and transmits the acquired signal to an external device 2000 by radio. The debugging circuit portion 1100 includes a setting unit 1120 and a radio transmitter 1140. In order to monitor the monitoring-target circuit portion 1200, the setting unit 1120 sets an isolation unit 1300 so as to make electrical connection between the debugging circuit portion 1100 and the monitoring-target circuit portion 1200. In addition, the setting unit 1120 sets a selector 1130 to select a signal line 1131 specified as a monitoring target. The radio transmitter 1140 acquires a signal on the signal line selected by the selector 1130 and transmits the acquired signal to the external device 2000 by radio.

  • Patent number: 7861010
    Abstract: An operation monitor system externally outputs a sufficient amount of condition information that indicates an internal operation condition, without using a dedicated terminal, that is to say, without a significant increase in cost. An output control unit of a semiconductor apparatus specifies an IF unit that is not currently performing input/output with respect to an IO unit, selects a selector connected to the specified IF unit, and outputs thereto a select signal indicating that the selected selector is to be used in the output of an internal operation output signal (internal monitoring data), which is the operation condition. The selector that has received the select signal selects the internal condition output signal, and outputs the selected internal condition output signal to an information collection apparatus via the IO unit.
