Abstract

PURPOSE:To execute the coincidence detection of a log of addresses by means of constitution of a few hardwares, by constituting so as to make one memory element have both the functions of an address coincidence register and a comparator circuit. CONSTITUTION:The memory address for which coincidence detection is required is provided to the address terminal group ADRS of the memory element 11. In this case, the element 11 becomes a write enable state by the input of logic ''0'' to the write enble terminal WE, and when a write data of logic ''1'' is provided to the data input terminal DI, a data of logic ''1'' is written in the element 11. Said operation is executed as to all the memory addresses for which coincidence detection is required. Subsequently, the element 11 is accessed, and its memory contents are provided to the data terminal D of the FF14 through the AND gate 13. Now, if the memory address shown in the main memory is an address for which coincidence detection is required, an output of the element 11 becomes logic ''1'', and the FF14 outputs a coincidence signal of logic ''1'' from the output terminal Q.
