- the pseudo arbitration block is executed when the access to the memory access block C140 is accepted and the trace function is executed, and when the access to the memory access block C140 is accepted and the trace function is executed.
- the access history here refers to the access block name, access type, memory address, and memory data.
- the arbitration block 150 receives each memory use request signal.
- the priority order is trace control block 17 0> memory access block A 1 2 0> memory access block B 1 3 0> memory access block C 1 40.
- Memory access block to the trace control block 110 using the microcomputer address bus 111, the microcomputer computer bus 111, and the microcomputer control signal 113 from the 110 It is assumed that initialization has been performed to store the access history of C140. First, the operation when the access history of the memory access block C140 is stored and an access other than that of the memory access block C140 is accepted will be described.
- Memory access block A 12 0 is a memory use request signal
- the arbitration block 15 when the memory access block B 13 0 sends the memory use request signal (including attribute information) 13 1 to the arbitration block 15 0, respectively.
- a value of 0 determines the acceptance priority of the memory use request signal, and returns a memory use approval signal to the memory access block indicating that the memory use request signal has been received for the memory access block with a higher order.
- the arbitration block 150 returns the memory use acknowledge signal 122 to the memory access block A 120, which has a higher priority of receiving the memory use request signal, and sends the memory control block 170 to the trace control block 170.
- the arbitration result signal (including attribute information) 173, the arbitration result address bus 174, and the arbitration result data bus 175 are output.
- the trace control block 170 it is checked whether the information based on the arbitration result matches the data set to store the access history.
- the trace control block 170 Since the initial setting is made to store the access history of the memory access block C140 in the memory, no match is found and the trace processing is not executed.
- the arbitration block 150 uses the memory control signal 151, the memory address bus 152, and the memory data bus 153 to transfer the request access of the memory access block A120 to the internal memory 1615. Run on 0. After the memory access block A 1 20 that has approved the memory use request has withdrawn the memory use request signal 1 2 1, the arbitration block 1 5 0 returns to the memory access block B 1 3 0 with the next highest reception priority. And performs the same processing. Next, the operation when the access to the memory access block C140 is accepted and the trace function is executed will be described. When the memory access block C140 sends the memory use request signal 1441 to the arbitration block 150, the arbitration block 150 accepts the request of the memory access block C140 and approves the memory use.
- the arbitration block 15 ⁇ outputs the arbitration result signal 173, arbitration result address bus 174, and arbitration result data bus 175 to the trace control block 170, and the memory control is performed.
- the request access of the memory access block C140 is executed to the internal memory 160 using the signal 151, the memory address bus 152, and the memory overnight bus 153.
- the trace control block 170 does the arbitration result signal 173, arbitration result address bus 174, and arbitration result data bus 175 match the data set to store the access history? In this case, the match is detected because the setting is the memory access block C140, and the trace control block 170 that detects the match sends the arbitration result signal 173 and arbitration result add Access history data from the arbitration result data bus 175 and the trace memory use request signal 171 and arbitration data bus 102 to trace the access history. Send the arbitration address bus 101. After the memory access block C140 approved of the memory use request has withdrawn the memory use request signal (including attribute information) 141, the arbitration block 150 sends a trace memory use request to the arbitration block 150. Signal 1 7 1 is input.
- the arbitration block 150 When the arbitration block 150 receives a trace memory use request from the trace control block 170, the trace memory use approval signal 17 7 is sent to the trace control block 17 °. 2 is returned, and the request access of the trace control block 170 is executed to the internal memory 160 using the memory control signal 151, the memory address bus 152, and the memory data bus 1553. . Finally, the operation when the pseudo arbitration block operates while the access to the memory access block C10 is accepted and the trace function is being executed will be described. When the memory access block C140 sends the memory use request signal 1441 to the arbitration block 150, the arbitration block 150 accepts the request of the memory access block C140 and approves the memory use. Returns signal 1 4 2.
- the arbitration block 150 sends the arbitration result signal 173, arbitration result address bus 174, and arbitration result data to the trace control block 170.
- the bus 175 is output and the request access of the memory access block C140 is performed by using the memory control signal 151, the memory address bus 152, and the memory bus 153. Execute for
- arbitration result signal 173, arbitration result address bus 174, and arbitration result data bus 175 match the data set to store the access history?
- the trace control block 170 that detected the match sent the arbitration result signal 173 and arbitration result address bus. 1 74, arbitration result data overnight bus Generates access history data from 175, traces memory access request signal 171 and arbitration data bus 102 to trace access history Send the arbitration address bus 101.
- the arbitration block 150 After the memory access block C140 approved for the memory use request has withdrawn the memory use request signal 141, the arbitration block 150 has the trace memory use request signal 171 and the new memory use request signal 171. Memory use request signal 1 2 1 is input. In the arbitration block 150, the request of the trace control block 170 having a higher reception priority is accepted, and the tracing memory use approval signal 172 is returned. At this time, the pseudo arbitration block 180 replaces the arbitration block 150 in order to make the system operation while tracing the access history data the same as the system operation when the access history data is not traced. Accepts memory use request signal 1 2 1 and returns memory use acknowledge signal 1 2 2 to memory access block A 12 0. At this time, the arbitration block 150 writes the access history data to the built-in memory 16 0 using the memory control signal 15 1, the memory address bus 15 2, and the memory data bus 15 3 No request is made to the internal memory 160 of the memory access block A120.
- the access history data is traced every time the memory access block C140 is accessed, but the memory use request signal generated during the trace processing is Only the memory use approval signal is returned by the pseudo arbitration block 180, but no operation is performed on the internal memory 160.
- the memory control block A 120, the memory access block B 130, and the memory access block C are controlled by the trace control block 170. Information required for operation analysis in the event of a failure by tracing the access history data of the memory access block required for the memory 160, which is accessible by a memory access block such as 140 Can be obtained, and it is easy to reproduce the failure occurrence, and the cause analysis can be performed smoothly.
- the access history data of one memory access block is described as an example of a trace in the evening.
- simultaneous tracing of a plurality of memory access blocks is also possible.
- a small-scale control circuit such as a trace control block can be provided without having a trace memory dedicated to access history data in the system.
- the information required for operation analysis at the time of failure occurrence can be obtained under the same conditions as when trace processing is not performed without increasing the load on the memory bus. The advantageous effect that the cause analysis can be performed smoothly can be obtained.
