The data transmission system comprises at least one master device and a plurality of slave devices, wherein the master device and the slave devices transmit data through a bus. The verification device comprises a distribution unit and a plurality of subtask units, wherein the number of the subtask units is determined based on a predetermined distribution rule; the distribution unit is used for distributing the data transmitted to the bus and the data received from the bus to corresponding subtask units based on the predetermined distribution rule; and the subtask units are used for receiving and storing the data which is transmitted to the bus and is distributed by the distribution unit, receiving the data which is received from the bus and is distributed by the distribution unit and comparing the data with correspondingly stored data which is transmitted to the bus. The device and the method for verifying the data transmission system can reduce the management and control complexity in the verifying process.
Description
Technical field
The present invention relates to the data management technique of data transmission system, particularly relate to the verification method and the device of data transmission system.
Background technology
Data transmission system comprises main equipment, slave unit and the bus that links to each other with slave unit with main equipment, and main equipment is by the bus access slave unit, and for example, main equipment can write the operation of data or reading of data by bus to slave unit.
Data transmission system can be integrated in system level chip (SOC), generally includes one or above main equipment, for example, and central processing unit (CPU), digital signal processor (DSP), demoder, image processor etc.; A plurality of slave units, for example storer, input-output device, interfacing equipment, external unit etc., and bus is the highway of transmission information or data between each main equipment and the slave unit among the SOC.Therefore, the correctness of checking bus architecture is to guarantee the key of system performance, also is the significant process that data transmission system is verified.
The proof procedure of data transmission system mainly comprises: when main equipment carries out write operation to slave unit, read and store the data (being the data that main equipment sends to bus) that main equipment will write slave unit, read data (being the data that bus sends to slave unit) that slave unit receives then and compare with the data that store, if identical then checking is passed through, if difference authentication failed then; When main equipment carries out read operation to slave unit, read and store the data (being the data that slave unit sends to bus) that read from slave unit, read data (being the data that bus sends to main equipment) that main equipment receives then and compare with the data that store, if identical then checking is passed through, if difference authentication failed then.
In the prior art, above-mentioned proof procedure can be defined as a checking bus architecture accuracy verification task usually, and along with the development of design and fabrication technology, system can integrated more master and slave equipment, main equipment also increases the accessing operation of slave unit thereupon, and therefore, the data volume that whole validation task need be managed is bigger, correspondingly manage and to control complexity also bigger, and finish whole validation task and need expend the long time.
In addition, in above-mentioned proof procedure, need a storer to store main equipment and will write the data of slave unit and the data that read from slave unit, after the data of a storage compared, the data that compared can be deleted, to store new data.Because master and slave hold facility bus requirements is through arbitration, when some data of storer (for example can't obtain the comparison chance for a long time, slave unit does not obtain writing data from bus, perhaps main equipment does not obtain reading of data from bus), will cause the follow-up data overflow storage that will store, and overflow for fear of storer, then need to increase memory span.And the increase of the data volume of storer also can increase the management and the control complexity of whole validation task.
Summary of the invention
The problem that the present invention solves provides a kind of demo plant and method of data transmission system, with management and the control complexity that reduces proof procedure.
For addressing the above problem, embodiment of the present invention provides a kind of demo plant of data transmission system, described data transmission system comprises at least one main equipment and a plurality of slave unit, described main equipment and slave unit pass through bus transfer data, described demo plant comprises allocation units and unit, a plurality of subtask, the quantity of unit, described subtask determines based on predetermined allocation rule, wherein
Described allocation units based on described predetermined allocation rule, send to the data allocations that the data of bus and described main equipment or slave unit are received from bus with described main equipment or slave unit and give corresponding unit, subtask;
Unit, described subtask receives and stores the data that send to bus that described allocation units distribute, and receives data that are received from bus that described allocation units distribute and compares with the data that send to bus of corresponding storage.
For addressing the above problem, embodiment of the present invention also provides a kind of verification method of data transmission system, comprising: produce a plurality of subtasks based on predetermined allocation rule; Based on described predetermined allocation rule, described main equipment or slave unit are sent to the data allocations that the data of bus and described main equipment or slave unit are received from bus give corresponding subtask; The data that are received from bus that the subtask of described correspondence will receive compare with the corresponding data that send to bus that receive.
Big with validation task data volume to be processed of prior art, data management and control complexity height, the proof procedure appearance ratio that expends time in, the allocation rule that the technique scheme foundation is scheduled to is divided into a plurality of checkings subtask with a validation task of bus architecture in the data transmission system, the data volume that handle each checking subtask significantly reduces, data management and control complexity reduce greatly, have therefore reduced the management and the control complexity of bus verification process relatively; And each checking subtask can executed in parallel, has therefore shortened the time of bus verification process relatively.
A validation task is divided into a plurality of checkings subtask, and the storer than low capacity can be used in each checking subtask, and is therefore also relatively easy for the data management and the control of storer, and also can reduce the possibility of data overflow storage.In addition, when mistake appears in proof procedure, only need to analyze the checking subtask of makeing mistakes, therefore the error correction of verifying is also simple.
