Abstract
A memory interface device of the present invention includes: an input buffer including a plurality of input areas; an output buffer including a plurality of output areas; and a control section for controlling the input buffer, the output buffer and a single port memory. The control section controls the input buffer and the single port memory so as to transfer a signal stored in one of the input areas of the input buffer to the single port memory while storing an input signal in another one of the input areas of the input buffer. The control section controls the output buffer and the single port memory so as to output as an output signal a signal stored in one of the output areas of the output buffer while transferring a signal stored in the single port memory to another one of the output areas of the output buffer.
