Abstract
A semiconductor chip includes a first common marker generating circuit and a second common marker generating circuit. The first common marker generating circuit is configured to send a first request signal to the second common marker generating circuit, the first request signal requesting a common marker to be sent to a second trace memory, and to send the common marker to a first trace memory, when a second request signal is received from the second common marker generating circuit, the second request signal requesting the common marker to be sent to the first trace memory. The second common marker generating circuit is configured to send the common marker to the second trace memory and to send the second request signal to the first common marker generating circuit, if a second core is running a user program at a time when the first request signal is received.
