Abstract

PURPOSE:To prevent charging from differing depending upon environment by carrying out the charging by finding the sum of the in-use time of an information processor except during main storage request operation and a value obtained by counting and converting the frequency of the occurrence of the main storage request operation into a time. CONSTITUTION:A means of measuring the in-use time of a device except during main storage request operation is composed of an address processing operation detecting means 101, a cash memory request operation detector 102, an arithmetic processing operation detecting means 103, an OR circuit 104, a main storage request operation detector 105, an inverting circuit 106, an AND circuit 107, and a timer 108. A means of measuring the time of the main storage request operation is composed of means 109 and 110 of detecting lead main storage request operation and write main storage request operation, respectively, AND circuits 111 and 112 which output one pulse by a clock, frequency counters 113 and 114, and means 115 and 116 of converting the frequency of the occurrence of the main storage request into a time. The times of the counter 108, and converting means 115 and 116 are summed up by an adding means 117 to achieve charging for the in-use time of an information processor without including the latent time of the main storage request.
