Abstract

PURPOSE:To generate pseudorandom numbers of a long cycle so that the capacity of the ROM is reduced and LSIs are introduced easily into this equipment, by using a plural number of data ROMs of small amount which can read out data at an independent cycle and by operating each data. CONSTITUTION:Contents of each address counter 1 and 2 are updated by an independent method, respectively. The contents of an ROM3 addressed by this counter 1 are inputted to an adder 5, and, similarly, the contents of another ROM4 addressed by the counter 2 are inputted to the adder 5. Both inputs are operated in the adder 5, and the result is outputted as random numbers from a signal line 8. Moreover, at the next cycle, addresses of counters 1 and 2 are individually updated. Thus the capacity of the ROMs 3 and 4 is reduced and introduction of LSIs into the random number generating equipment can be made easily.
