Abstract
A control apparatus controls writing and reading of data with respect to a memory which is randomly accessible. An address producing device produces an address by a method according to a predetermined rule, in response to a request to access the memory by the method according to the predetermined rule. A switching device selects one of an address with which the memory is randomly accessed and the address produced by the address producing device. Data is written into and read from the memory, at a location that corresponds to the address that is selected by the switching device and supplied to the memory. It is advantageous to provide a control device which supplies a switching signal to the switching device to cause the switching device to select one of the address with which the memory is randomly accessed and the address produced by the address producing device, depending upon the presence of a request to access the memory by the method according to the predetermined rule and the presence of a request to randomly access the memory.
