IPC: G06F11/22
Filed: 1988-06-23
Abstract: PURPOSE:To prevent the disturbance of a normal system operating work by giving a means to a test program itself to decide whether a device to be tested is separated from a system or not. CONSTITUTION:A test program scheduling means has a schedule so that a test program designated externally is carried out on a device to be tested. A separation information deciding means checks the separation information stored in the device by the deciding means itself to confirm whether this device is separated from a system or not. If so, the device can execute a scheduled test program. If not, the device is prevented from carrying out the scheduled test program. Thus it is possible to prevent a case where the test program is carried out via a device that is not separated unwittingly from the system.

IPC: G06F12/08
Filed: 1993-06-28
Abstract: PURPOSE:To provide a cache memory control system which can assign a read only memory which can not be rewritten as a cache memory. CONSTITUTION:A decoder 23 once detecting the write to the ROM 31 outputs a snooping signal (d) to a CPU 10 through an OR circuit 24. Then the CPU 10 retrieves whether or not data in an address of the ROM 31 is present in an internal cache memory 12 is present and makes the data in the address of the cache memory 12 ineffective when the data is present. Consequently, the contents of the cache memory 12 and ROM 31 are prevented from becoming discrepant. Further, the decoder 23 once detecting the write to the ROM 31 sets an interruption register 35 and outputs an interruption signal (g) to the CPU 10. Consequently, the execution of a program which performs wrong operation such as writing to the ROM 31 can be interrupted.
