(5), electronics multiple channels address signal (6) is used for the storage unit in the selection memory (7);

(6), the process of once counting: the content in (5) step in the selected storage unit at first is read in 16 two-way read-write registers (12), 16 are preset up counter (13) and add 1 counting on the bases of reading in the content currency, 16 bit data behind the counting still store in 16 two-way read-write registers (12), and write the storer described in (5) step (7) storage unit in, finish once counting, the content with 16 electronics multiple channels address signals (6) of identical value deposits same storage unit in;

(7) repeat each step of aforementioned (1)-(6), to the counting end.

Characteristics of the present invention are:

1, single step-by-step counting function is carried out organic the combination with the characteristic type tally function, can on programmable logic device (PLD), realize the high-speed multifunctional counter of step-by-step counting function and characteristic type tally function;

2, the collection of characteristic information both can realize by the pulse counter module in the multi-functional counter, also can adopt 16 high-speed parallel port high speed acquisition;

3, the high capacity twoport storage chip of multi-functional counter employing up to 16 can effectively write down the nearly information of 64K passage as memory storage, and the maximum count value of each passage also reaches 64K.

The invention has the advantages that:

1, big, the single-channel count value height of multiple tracks capacity

The capacity of electronics multiple channels address can reach 65536 among the present invention, promptly can carry out differential count to 65536 kinds of characteristic informations.The count value of each passage is up to 16 (64K).

2, multi-functional

The present invention selects input end can select to be operated in the step-by-step counting mode of operation by adopting the numerical characteristic signal, also can carry out tagsort by numerical characteristic signal input part up to 16, simultaneously, 16 characteristic signal can also carry out combination in any at circuit, realizes the combination of various characteristic informations.

3, high-speed

Entire circuit is based upon high-speed programmable logical circuit and high-speed memory, and its work period is being operated under the numerical characteristic signal preference pattern all up to 40ns, single count cycle even less than 200ns.

4, can store

The present invention can note the count value of all electronics passages, reads for low-speed interface.

The present invention not only can be applied to flight time mass spectrum (grain spectrum) and wait in the instrument that needs to count by tagsort, is used for differential count bulky information at a high speed.And can be applied to arbitrarily in the high-speed counter circuit by tagsort.
