Abstract
An apparatus for automatically preparing a bus interface preparation apparatus is provided which is capable of preventing duplication of addresses of registers and memories. When data of a hardware description are input into the extracting portion , the extracting portion extracts from the data whether the memory element is a memory device or an FF. The extracting portion reads the top address and the address size of the memory element when the memory is the memory element and reads address when the memory is an FF, and the thus read data are output to the address competition detecting portion . The address competition detecting portion detects competition of the addresses by determining whether the address information stored in the bit data memory portion includes . The output portion converts the data concerning address of the memory into a description language of the hardware of the bus interface circuit.
