Summary of the invention
Technical matters to be solved by this invention is: the method for a kind of Lookup protocol concatenation unit address is proposed, solve in conventional art adopt toggle switch be arrange increase system cost, reliability that rank addresses brings low, can't be applicable to the problem that large-scale combination address arranges.
The present invention solves the problems of the technologies described above the technical scheme adopted:
The method of a kind of Lookup protocol concatenation unit address comprises the following steps:
A. by the control signal wire of each row concatenation unit from left to right order be connected, and the concatenation unit that will be positioned at the lastrow end of line is connected with the control signal wire of the concatenation unit of next every trade head;
B. in sending to the steering order of concatenation unit, add the numbering i of the total columns n of combination and active cell, the value of the numbering i of described active cell is initialized to 1;
C. concatenation unit is when receiving steering order, according to the value of the numbering i of the total columns n of combination and active cell, automatically calculate the row, column address of this concatenation unit at combination, and the cumulative new steering order of 1 rear formation of the value of the numbering i of the active cell in steering order is sent to next concatenation unit, return to step c.
Further, in step c, the value of described numbering i according to the total columns n of combination and active cell is automatically calculated the concrete grammar of this concatenation unit in the row, column address of combination and is:
After row address r=(i-1)/n rounds+1;
Column address c=i-n* (r-1).
The invention has the beneficial effects as follows: automatically calculate the row, column address of concatenation unit in combination by software mode, do not need to configure extra hardware device, can reduce system cost, save hardware resource, the stability of raising system, and the address that can be applicable to the concatenation unit in large-scale combination arranges.
The accompanying drawing explanation

Fig. 2 is the method flow diagram of the Lookup protocol concatenation unit address in the present invention.
Embodiment
The present invention is intended to propose the method for a kind of Lookup protocol concatenation unit address, solve in conventional art adopt toggle switch be arrange increase system cost, reliability that rank addresses brings low, can't be applicable to the problem that large-scale combination address arranges; Its main thought is: be to carry out dissection process by the steering order that the concatenation unit automatic butt is received, according to the total columns of spelling wall and the current number information in steering order, carry out corresponding computing, calculate the row, column address of concatenation unit.
In order to allow each concatenation unit can obtain each self-corresponding correct current number information, need to be by the control signal wire exact connect ion of each concatenation unit, the combination capable by M, that the concatenation unit of N row forms of take is example, as shown in Figure 1, its connected mode is: each row is connected by control signal wire from left to right, and the first concatenation unit of the concatenation unit of the end of line of lastrow and the row of next line is connected by control signal wire.
As shown in Figure 2, the method flow of the Lookup protocol concatenation unit address in the present invention comprises the following steps:
1, each concatenation unit that is linked in sequence: by the control signal wire of each row concatenation unit from left to right order be connected, and the concatenation unit that will be positioned at the lastrow end of line is connected with the control signal wire of the concatenation unit of next every trade head;
2, in steering order, add total columns n of combination and the numbering i of active cell, initialization i=1; In sending to the steering order of concatenation unit, add the numbering i of the total columns n of combination and active cell, the value of the numbering i of described active cell is initialized to 1;
3, the concatenation unit of receiving steering order calculates the rank addresses in combination automatically according to the value of n and i: concatenation unit, when receiving steering order, calculates the row, column address of this concatenation unit at combination automatically according to the value of the numbering i of the total columns n of combination and active cell;
4, arrange after i=i+1 and form new steering order and send to next concatenation unit: the cumulative new steering order of 1 rear formation of value to the numbering i of the active cell in steering order sends to next concatenation unit, returns to step 3.
On concrete enforcement, two bytes in steering order are defined as and spell the total columns n of wall and active cell numbering i, the value of active cell numbering i is initialized to 1, annexation based on above-mentioned each concatenation unit, steering order always enters from first (being positioned at the 1st row the 1st row) concatenation unit, now the active cell of this concatenation unit is numbered i=1, and when receiving steering order, this concatenation unit calculates its row, column address in combination according to following formula:
After row address r=(i-1)/n rounds+1;
Column address c=i-n* (r-1).
And this concatenation unit sends to next concatenation unit after after the value cumulative operation of execution (being i=i+1) of the numbering of the active cell in steering order i, forming new steering order together with other information in steering order, so, when the concatenation unit of the first row secondary series is received steering order, resolve the value of active cell numbering i, i=2 now, it still calculates its row, column address in combination by above-mentioned formula, in this manner, each concatenation unit that is arranged in combination all can calculate the row, column address at combination automatically.
