Abstract
Abstract A data distributing method and an apparatus employing such method are disclosed, wherein a memory group stores the cumulative value of weighted values indicating data processing load of each kind of data or work unit outputted from a coupling unit. A control circuit recognizes the kind of data that is inputted to each of two input lines of the coupling units, judges whether or not there is a deviation in distribution of data or work units which are transferred from a first memory group to a second memory group on the basis of the cumulative value stored in the memory groups that correspond to the kinds of data recognized, and changes over connection patterns of switch in the coupling unit so that any deviation is corrected, thereby equally distributing the data processing load of data or work units to the second memory group.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
200 words
A data distributing apparatus having a plurality of coupling units which are provided between a first group of devices and a second group of devices to distribute information received from said first group of devices to said second group of devices so that the processing load for each kind of information in said second group of devices is equalized, wherein each of said coupling units comprises: a data switch having a plurality of data input lines for receiving a plurality of pieces of information and a plurality of data output lines for outputting a plurality of pieces of information received; a group of a plurality of memories respectively corresponding to a plurality of different kinds of information, each memory accumulating and storing a cumulative value for the processing load of each kind of information outputted from said coupling unit; and a control circuit which detects deviation of the distribution of processing load of information transferred from said first device group to said second device group on the basis of the values stored in said memories, changes over data connection patterns in said coupling unit so that any deviation is corrected, and then distributes information to said second group of devices.
Claim 2
Dependent Claim
202 words
A data distributing apparatus having a plurality of coupling units which are provided between a first group of devices and a second group of devices to distribute data or work units from said first group of devices to said second group of devices according to a predetermined rule, wherein each of said coupling units is provided with a group of a plurality of accumulators respectively corresponding to a plurality of different kinds of data or work units, and a control circuit which controls said accumulators and changes over data connection patterns on the basis of the contents of said accumulators, each of said accumulators accumulating and storing a cumulative value for the processing load of each kind of data or work unit outputted from said coupling unit, and said control circuit being arranged to judge whether or not there is any deviation in the distribution processing load of data or work units transferred from said first device group to said second device group on the basis of the contents of said accumulators, to change over the data connection patterns in said coupling unit so that any deviation is corrected, and to distribute data or work units to said second group of devices.
Claim 3
Dependent Claim
177 words
In a data distributing apparatus having a plurality of coupling units which are provided between a first group of devices and a second group of devices, each coupling unit having a data switch which has two data input lines for receiving two pieces of information and two data output lines for outputting two pieces of information received, a method of equally distributing to said second group of devices the processing load of each kind of a plurality of pieces of information received from said first group of devices, said method comprising the steps of: recognizing the kinds of said two pieces of information received; accumulating and storing the cumulative values of pieces of information outputted from said two output lines, respectively, for each kind of information; calculating the difference W between the stored cumulative values concerning said two pieces of information received; calculating the sum V of processing load concerning said two pieces of information received; and changing over connection patterns in said data switch on the basis of the values calculated by said W and V.
Claim 4
Dependent Claim
98 words
A data distributing method according to Claim 3, wherein said step of changing over connection patterns in said data switch on the basis of said values calculated effects change-over control such that, if |W+V| > |W-V| , said first input line is connected to said second output line and, at the same time, said second input line is connected to said first output line, whereas, if |W+V| ≦ |W- V| , said first input line is connected to said first output line and, at the same time, said second input line is connected to said second output line.
Claim 5
Dependent Claim
68 words
A data distributing method according to Claim 4, wherein said step of calculating the difference between the stored values concerning said two pieces of information received is to subtract the value stored in the accumulator corresponding to the kind of information piece inputted to said second input line from the value stored in the accumulator corresponding to the kind of information piece inputted to said first input line.
