ABSTRACT:
In an access processing system in an information processor, the information processor includes: an access device (10, 11) for generating an access request signal; an accessed device (13) provided with a memory means (30) that is accessed by the access device (10, 11); and an address bus (14) that has the access device and accessed device connected with the information processor at least by the address bus (14).
The access processing system is processed such that, if an access request is produced, when the access request signal does not require all bits in the address bus (14), an unused bit in the address bus (14) is loaded with write data to deliver it to the accessed device (13).
