BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a byte / word conversion device for wideband communication, and in particular, to receive data through a system bus in an expansion slot portion of a workstation in wideband communication. The present invention relates to a byte / word conversion apparatus for broadband communication suitable for converting 8-bit byte data into 32-bit word data.

In this regard, FIG. 1 illustrates an embodiment of converting and receiving byte data into word data when receiving data through a system bus of an extended slot portion of a workstation in a conventional broadband communication. First, First, Second, Third, and First FIFOs (10, 20, 30, 40) for first-in first-out, respectively, word-by-word data in byte unit data, for explaining. And a connection unit 60 for simultaneously receiving data of each byte unit of the first, second, third, and fourth packets 10, 20, 30, 40 in word units and connecting them to the next stage. The read signal of 60 is inverted and simultaneously applied to each of the first, second, third, and fourth fabrics 10, 20, 30, and 40 as a read signal, respectively. The fourth packet (10, 20, 30, 40) outputs data in units of bytes at the same time, and eventually outputs data in units of words. It consists of an inverter (Inverter) (50).

According to the related art, the first, second, third, and fourth packets 10, 20, 30, and 40 are first received with word units of data in byte units, and then the connection unit 60 By applying a read signal to each of the first, second, third, and fourth envelopes 10, 20, 30, and 40 through the inverter 50, each of the first, second, third, and fourth envelopes 10, 20, 30, and 40 simultaneously output data in units of bytes, so that the connection unit 60 is simultaneously supplied with data in units of words and connected to the next stage.

That is, the system bus of the expansion slot portion of the workstation receives data in which data in bytes is converted into data in words and applies them to a predetermined device therein.

However, in such a conventional technique, a plurality of expensive first, second, third, and fourth wrappers 10, 20, 30, and 40 must be used to convert data in bytes into word data. This is a costly drawback.

Disclosure of Invention The present invention has been made to solve the above-mentioned drawbacks of the prior art, and provides a byte / word conversion apparatus for wideband communication that can convert data in byte units into data in units of words using only one packet. There is this.

Hereinafter, with reference to the accompanying drawings an embodiment of the present invention for achieving the above object is as follows.

Referring to FIG. 2, FIG. 2 is an embodiment of converting and receiving byte data into word data when receiving data through a system bus of an extended slot portion of a workstation in the broadband communication according to the present invention. A block diagram for explaining an example includes a connection section 110 for connecting word units with front and rear ends, and control signals for processing word units of data into byte units while communicating with the connection unit 110. The control unit 120 for inputting / outputting, the PPO 130 for outputting the applied data in units of bytes according to the signal of the control unit 120, and the control unit 120 is connected in parallel between the PPO 130 and the connection unit 110 According to the signal of the data in the unit of word is divided into each byte unit and stored and output at the same time so that the data is applied to the connection unit 110 in units of words 1, 2, 3, comprises a fourth register (Register) (140,150,160,170).

According to the present invention made as described above, first, the connection unit 110 connects data in word units with the front and rear ends, and the controller 120 communicates with the connection unit 110 to process data in word units as data in byte units, respectively. Input and output each control signal.

Next, the PPO 130 outputs the applied data in units of bytes according to the signal (/ rd) of the controller 120, and the first, second, third, and fourth registers 140, 150, 160, and 170 are connected to the PPO 130. It is connected in parallel between the connection unit 110 to store the data in the unit of word by byte unit in accordance with the signal (wr1, wr2, wr3, wr4) of the control unit 120, respectively, and simultaneously output the data to the connection unit 110 Is applied in word units.

That is, the connection unit 110 applies each control signal (rd, / SS, / AS) to the control unit 120 to read the data in a word unit, so that the control unit 120 reads the data to the capsule 130. The signal / rd is applied to the cover 130.

Subsequently, the controller 120 sequentially applies the signals wr1, wr2, wr3, and wr4 to the first, second, third, and fourth registers 140, 150, 160, and 170, respectively, and sequentially outputs the bytes from the PPO 130. The unit data is sequentially stored in each of the first, second, third, and fourth registers 140, 150, 160, and 170.

Next, the control unit 120 applies a signal / ACK to the connection unit 110 so that the connection unit 110 simultaneously receives data from each of the first, second, third, and fourth registers 140, 150, 160, and 170. The connection unit 110 reads the data in word units and outputs the data to the next stage.

As described above, the present invention uses relatively low-cost first, second, third, and fourth registers 140, 150, 160, and 170, and only one relatively expensive packet 130 uses byte data in word units. This can reduce the cost of the device.
