Claim 3

Dependent Claim 39 words

In a data processing system, the combination as claimed in claim 1, wherein said settable device comprises manual switch means for setting the predetermined number; and wherein said given status indication is the busy condition of a peripheral unit.

Claim 4

Dependent Claim 249 words

In a data processing system, the combination as claimed in claim 2, wherein there are two of said settable devices comprising manual switch means for setting separate predetermined numbers for cut-in level and cut-out level respectively, and wherein there are two of said comparison means for cut-in level and cut-out level respectively, the comparison means for cut-in level having inputs from the settable device for the cut-in level and from the counting means, and the comparison means for cut-out level having inputs from the settable device for the cut-out level and the same counting means, and wherein there are two of said bistable devices connected respectively to indicate the outputs of the two comparison means, wherein with the predetermined number for the cut-in level greater than the predetermined number for the cut-out level, if the number of peripheral units busy during a cycle is equal to or greater than the predetermined number for the cut-in level then both of the bistable devices are set, if the number of peripheral units busy during the cycle is less than the predetermined number for the cut-out level neither bistable device is set, and if the number of busy peripheral units is equal to or greater than the predetermined number for the cut-out level and less than the predetermined number for the cut-in level then the bistable device indicating the cut-out level only is set during the cycle, both of the bistable devices being reset once each cycle along with the counting means.

Claim 5

Dependent Claim 152 words

In a data processing system, the combination as claimed in claim 3, further including a common bistable device, gate means coupling the outputs of the cut-in level and cut-out level indicating bistable devices respectively to set and reset inputs of the common bistable device, means effective once each cycle before the reset of the cut-in level and cut-out level bistable devices and counting means, and effective after the counting of all of the busy peripheral units to enable said gating means to set the common bistable device in response to the cut-in level indicating bistable device being set, and to reset the common bistable device in response to the cut-out level indicating bistable device being in the reset condition, the common bistable device remaining in its previous state if the cut-in level indicating bistable device is in the reset condition and the cut-out level indicating bistable device is in the set condition.

Claim 6

Dependent Claim 184 words

In a data processing system, the combination as claimed in claim 4, wherein there are two categories of said peripheral units, with the register for each peripheral unit including a category-indication store (C1 of Row 1); wherein said traffic monitor, for each category of peripheral units, includes apparatus having its own said counting means, its own said comparison means, two of said settable devices, and cut-in level and cut-out level indicating bistable devices, and its own said common bistable device, whereby the common bistable device for each category may be controlled in accordance with its own cut-in level and cut-out level values; and wherein there is further a control bistable device (110), wherein the output of the read buffer corresponding to said category-indicating store controls the input to the counting means to advance the counting means in accordance with the status condition indication for the corresponding category of peripheral units, and wherein the category-indication from the read buffer also controls said control bistable device to be selectively set if the common bistable device for that category of peripheral units has been set each cycle.
