<p>PURPOSE:To initialize a memory and a memory circuit without using any exclusive hardware by supplying the output received from an address register storing the address of the memory to the memory circuit at initialization. CONSTITUTION:The specific data is set at a memory data register 4 and a 1st address register 2 storing the address of a memory 1 is added via an adder 3. At the same time, the entire area of the memory 1 is initialized. In such a case, the optional several bits of the register 2 are taken out and supplied to a memory circuit (internal register) 6 via a multiplexer 9. Thus the optional data supplied from an arithmetic circuit 5 is also set at the register 6. Then the register 6 is also initialized and no addition circuit is required for initialization of a 2nd address register 7 which stores the address of the register 6. Thus the hardware quantity is reduced.</p> |
