The package abnormality monitoring unit 11 receives a PWR alarm from the monitored packages 21 to 2n and mounting information such as a mounting state, and outputs an enable signal to the input buffer 161.
To 16n. In addition, each monitoring target package 21
2n are also input to the input buffers 161 to 16n of the CPU package 1, and the input buffers 161 to 16n receive the transmission amount allocation change request signal based on the enable signal. Since the received transmission amount assignment change request signal may be generated asynchronously with respect to the clock output from the signal processing unit 12, the temporary holding circuit 17 Is held in. The holding time is set by the SET output from the pulse generator 13.
This is a period from when a signal is input to when a RESET signal is input.

In the data read / write circuit 14, a signal group (H level or L level) temporarily held for each package to be monitored is stored.
Level) is used as a control signal for reading an address of a device or the like in the package to be monitored stored in the ROM 15, and the data stored in the ROM 15 is read at the timing of an RE signal input from the pulse generator 13. At the same time, the read ROM data is written into the RAM 9 at the timing of the WE signal input from the pulse generator 13.

In the main data transmission / reception section 8, the signal processing section 12

For this reason, according to the present embodiment, the CPU
The data transmission / reception transmission amount setting means 10 in the package 1
Since the temporary holding circuit for adjusting the timing is not required, the size of the data transmission / reception transmission amount setting unit can be reduced.

As described above, in order to reduce the circuit scale of the main data receiving unit 8 and the data transmitting / receiving unit 4 in each monitoring target package without using the monitoring bus 3 in the form of only the data line, the monitoring bus 3 is added to the data line. A monitoring bus can be provided by adding a clock line, and a monitoring bus can be provided by adding a clock line and a frame pulse signal line in addition to the data line.

In the embodiment described above, the CP
In the example described above, the adjustment and control of the number of data by the U package are performed by transmitting the address information of the memory of the data transmission / reception unit of the monitoring target package. However, the adjustment control is performed by specifying the alarm item of the signal processing unit of the monitoring target package. Can be done. Also, the CPU package is

According to the present invention, the allocation of the number of data for transmitting detailed alarm information of each package to be monitored on the monitoring bus is determined in advance by a signal declared from each package to be monitored. It is possible to optimally assign the number of data for transmitting the detailed alarm information of each monitoring target package according to the alarm information item and the alarm information amount.

Further, according to the present invention, the CPU package separately receives the mounting information of the package to be monitored, and allocates the transmission amount based on the mounting information. Therefore, it is possible to immediately monitor the package mounting status and the like. Further, it is possible to prevent a huge amount of unnecessary data or uncertain data from being transmitted on the monitoring bus when the package mounting state is not appropriate, and to efficiently allocate the data transmission amount on the monitoring bus. I do.
