Description

DATA RECEIVER OF TRANSMISSION SYSTEM

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a transmission system, and more particularly, to a data receiver for receiving data.

In today's world, a lot of information is exchanged, which can be said to be the era of information and communication. Communication means has emerged as an important tool in the era of information and communication that connects the information sender and the receiver who wants to receive the information. Among the communication means, a modem or a telephone for transmitting a voice that enables communication through a computer is now an indispensable element for users. The method of transmitting / receiving the information may include a wireless communication that transmits / receives the information by using a cable transmission and a radio frequency that transmit / receive the information through a transmission line. radio transmission).

BACKGROUND With the development of the communication system, semiconductor devices have been developed to increase the degree of integration of semiconductor devices used in portable devices. In particular, the layout area occupied by the transmission line in the semiconductor device that transmits and receives the data having the information through the transmission line may also determine the degree of integration of the semiconductor device. In general, the transmission lines are divided into transmission lines for transmitting data and addresses. As a result, the transmission line is a major obstacle to the development trend of the semiconductor device and the communication system.

It is therefore an object of the present invention to provide a receiving apparatus of a communication system capable of receiving data and addresses transmitted through one transmission line.

(Configuration)

According to one aspect of the present invention for achieving the above object, a receiving apparatus of a communication system that receives a predetermined address and data has a plurality of digital signal processing circuits, and the data in response to a clock signal from the outside. Digital signal processing means for receiving; And data receiving means for receiving the address and the data, classifying the address and the data according to whether the clock signal is applied or not, and supplying the data to one digital signal processing circuit corresponding to the address. .

In this embodiment, the receiving means is a digital-to-analog converter for converting the address and the data into an analog signal, and the digital signal for converting an analog signal from the digital-to-analog converter into a digital signal and corresponding to the address. An analog-to-digital converter to select the signal processing circuit.

(Action)

By such an apparatus, data and addresses transmitted through one transmission line can be received.

(Example)

Hereinafter, reference will be made in detail with reference to FIGS. 1 and 2 according to an embodiment of the present invention.

Referring to FIG. 1, the receiving apparatus of the novel communication system of the present invention includes a digital-to-analog converter 100, an analog-to-digital converter 200, and a digital signal processor 300. The digital-analog converter 100 converts the address and data of a digital component transmitted from a predetermined data transmission means into an analog signal. The analog-to-digital converter 200 converts the address and data converted into an analog signal by the digital-to-analog converter 100 into a digital signal, and corresponds to that of the digital signal processor 300 corresponding to the address. Select one digital signal processing circuit. The digital signal processing unit 300 includes a plurality of digital signal processing circuits 310, 320, 330, and 340. Each of the digital signal processing circuits 310, 320, 330, and 340 is selected by the analog-to-digital converter 200, and the selected one of the digital signal processing circuits is controlled by an external clock CLK. Accept the data from analog-to-digital converter 200. Thus, the receiving device according to the present invention can receive the address and the data supplied through one transmission line.

In the following description, the same or similar reference numerals and signs in the drawings represent the same or similar components as much as possible.

1 and 2, a reception apparatus of a communication system according to the present invention includes a digital-to-analog converter 100, an analog-to-digital converter 200, and a digital signal processor 300. The digital-to-analog converter 100 converts an address ADDR and data of digital components transmitted from a predetermined data transmission means (not shown) into an analog signal AS. do. The analog-to-digital converter 200 converts the address ADDR and data DATA, which are converted into the analog signal AS by the digital-to-analog converter 100, into a digital signal DS. Then, one corresponding digital signal processing circuit of the digital signal processing unit 300 corresponding to the address is selected.

The digital signal processing unit 300 includes a plurality of digital signal processing circuits 310, 320, 330, and 340. Each of the digital signal processing circuits 310, 320, 330, and 340 is selected by the analog-to-digital converter 200, and the selected one of the digital signal processing circuits is controlled by an external clock CLK. Accept the data from analog-to-digital converter 200.

The address ADDR and data DATA of FIG. 2 are supplied through one transmission line, and the address ADDR and data DATA to be transmitted are transmitted to the address ADDR and data by the clock CLK. Separated by (DATA). For example, when a predetermined transmission signal is transmitted from the predetermined data transmission means to the receiving device through the transmission line, the receiving device receives the address ADDR and the data DATA based on whether the clock CLK is applied. ). That is, when the clock CLK is not applied, the transmission signal means the address ADDR and when the clock CLK is applied, the transmission signal means data.

Thus, the analog-to-digital converter 200 uses one of the digital signal processing circuits 310, 320, 330, and 340 by using the address ADDR, which is a transmission signal before the clock CLK is applied. Select the processing circuit. One digital signal processing circuit selected by the analog-to-digital converter 200 receives data from the data transmission means in response to the clock CLK. Thus, the address ADDR and the data DATA supplied through one transmission line according to the present invention can be received.

In the above, the configuration and operation of the circuit according to the present invention is shown according to the above description and drawings, but this is merely described for example, and various changes and modifications are possible without departing from the technical spirit of the present invention. .

As described above, by dividing the transmitted address and data according to whether the clock is applied, the address and data supplied through one transmission line can be received.
