Abstract

PURPOSE:To transfer a low speed data to a high speed output line by storing once a data from plural low speed input lines and converting the data group divided spatially to plural input lines into a series of data string. CONSTITUTION:Transmission data 1-6 are inputted to a data transmission equipment 001 while being divided into low speed input lines 101-103 being 3 data transmission lines and stored in a storage section 010 for temporary storage. When one frame data to be sent is stored in the storage section 010 next, the end of transmission is reported from a low speed side line control section 012c to a processing section 011, which gives a transfer instruction to a high speed side line control section 013, and the section 013 outputs a data from the storage section 010 to a high speed output line 104 at high speed. The data in plural low speed lines is stored once in this way, then the similar effect to the connection of the transmission line having apparently n-time transfer speed is obtained.

Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a data transfer device, and in particular to a data transfer device that converts data divided into n low-speed spatial divisions into one high-speed output data. This relates to a transfer device.

The number of space division lines on the low-speed side and the number of channels on the output high-speed line were the same.

[Problem that the invention seeks to solve]

The above-described conventional high-speed device has a problem in that its output line has a single speed.

In addition, the conventional speed conversion transfer device, which is the high-speed change device mentioned above, is a simple multiplexing device, so the output transfer speed of the device on the input side of the conversion device is low, and the line transfer speed is the bottleneck in the system. However, there was a problem in that the throughput of the system did not improve even if the processing device was improved.

[Means for solving problems]

A data transfer device according to the present invention includes a line control unit that controls a plurality of input lines and an output line, a storage unit that stores data from the plurality of input lines, and a start of data from the plurality of input lines. and a processing unit that detects the end of the data and instructs the data to be transferred to the output line, and converts the data group spatially divided into a series of data strings to the plurality of input lines. The data group that has come is stored in the storage section, and the processing section converts the data group into a series of data strings, which are then transferred to the high-speed output line.

[For production]

In the present invention, data from a plurality of low-speed input lines is stored in one batch, and a data group spatially divided into the plurality of input lines is converted into a series of data strings and transferred to a high-speed output line.

〔Example〕

Hereinafter, embodiments of the present invention will be described in detail based on the drawings.

The figure is a configuration diagram showing an embodiment of a data transfer device according to the present invention.

In the figure, 001 is a data transfer device, 010 is a storage unit that stores data from multiple input lines, and 011 is a unit that detects the start and end of data from multiple input lines and instructs all transfers to output lines, and a processing unit that converts the data group spatially divided into the plurality of input lines into a series of data strings;
012a to 012c and 013 are line control units that control a plurality of input lines and output lines, and this line control unit 0
12a to 012c and 013 constitute low speed and high speed line side (goods) sections. 1m to 103 are low-speed side input pictures M, and 104 is a high-speed side output line, which constitute a data transmission line. Also,■、■・・・・・・・・・■
is the transferred data.

Then, the data group transferred in a space-divided manner at a low speed is stored in the storage unit 010, and the processing unit 011 converts the data group into a series of data strings to be sent to the high-speed output line 104. configured to transfer.

Next, the operation of the embodiment shown in this figure will be explained.

First, the transfer data ■ to [F] are divided into three data transmission lines, low-speed input lines 101, 102, and 103, input to the data transfer device 001, and stored in the storage unit 010 for temporary storage. .

Next, when one frame of data to be transferred is accumulated in this storage unit 010, the low-speed side line control unit 012c reports the end of transfer to the processing unit 011, and this processing unit 0
11 issues a transfer instruction to the line control unit l1ll'13 on the high-speed side, and the line control unit O'13 on the high-speed side transfers the data to the storage unit 010.
The data is output to the high-speed side output line 104 at high speed.

〔Effect of the invention〕

As explained above, according to the present invention, by accumulating data on multiple low-speed lines at once, it is possible to inject the same effect as if the data were connected to a transmission line with n times the transfer speed. .
