APPARATUS AND METHOD FOR CONTROLLING SINGLE PORT MEMORY OF BI-DIRECTIONAL DATA COMMUNICATION

摘要

A single port memory control apparatus for bi-directional data communication and a control method thereof are provided to reduce the number of RAM for buffering data by performing reading/writing transmission/receiving data from a memory composed of an external synchronous signal port RAM. A single port memory control apparatus for bidirectional data communication includes a transmission control unit(120), a receiving control unit(110), a mediation control unit(103), and a mode selection unit(104). The transmission control unit(120) generates read/write signals for a transmission packet frame by using write/read enable-signals and write data of the transmission packet frame generated in a transmission terminal. The receiving control unit(110) generates read/write signals for a receiving packet frame by using the write/read enable-signals and write data of the receiving packet frame generated in a receiving terminal. The mediation control unit(103) mediates the reading/writing of a memory for the transmission/receiving packet frames which are inputted from the transmission control unit(120) and the receiving control unit(110) according to an operation mode. The mode selection unit(104) outputs an operation mode signal to the mediation control unit(103).
