In order to make those skilled in the art better understand technical solution of the present invention, below in conjunction with drawings and Examples, be described in detail.
A kind of flow process that downloads to the hardware component generation method of reconfigurable hardware body that the embodiment of the present invention provides is comprised of preprocessing process and control procedure.
Wherein:
Preprocessing process as shown in Figure 1, comprises the following steps:
Step S101, storage are corresponding to the driving function of reconfigurable hardware body.
For example: when the fpga chip of this reconfigurable hardware Ti Wei xilinx company, the FPGA driving function that the ISE developing instrument of storage xilinx company provides.
Step S102, the storage abstract adaptation collection of functions corresponding with each member position in equipment, and the corresponding relation of setting and driving function.
The position of member in equipment comprises position and the member position in affiliated assembly of assembly in equipment under member, for each member position, all has abstract adaptation function in contrast should.
The corresponding relation of driving function and abstract adaptation function is set, and this corresponding relation can be one to one, can be also one-to-many, for example the simultaneously corresponding driving function of a plurality of abstract adaptation functions.
The corresponding hardware of step S103, setting and network environment unit component base, each hardware unit component base comprises at least one hardware unit member.
According to the difference of network environment, different hardware unit component bases is set, each hardware unit component base comprises at least one hardware unit member, this hardware unit member can generate in advance, has certain common function.The hardware unit member that for example " there is queue function and queue management function ".When initial, first component base can be sky, along with user's development process constantly increases.
It should be noted that between above-mentioned each step of listing, not have sequencing, specifically first carry out the realization which step does not affect the embodiment of the present invention.
Control procedure as shown in Figure 2, comprises the following steps:
Step S201, reception user's indication generates the command information of object member.
This command information is carried positional information, network environment information and the function information of object member;
Step S202, according to the positional information in described command information, determine abstract adaptation function.
Determine the abstract adaptation function corresponding with object member position.
Step S203, definite driving function corresponding with this abstract adaptation function.
Step S204, according to described network environment information, in corresponding hardware unit component base, determine and the corresponding hardware of described function information unit member.
Step S205, utilize definite driving function to call described hardware unit member, generate object member.
Suppose, the fpga chip of reconfigurable hardware Ti Wei xilinx company, driving function is the FPGA driving function that ISE developing instrument provides, after above-mentioned preprocessing process, when user specifies the hardware component that generates " having input/output function and table lookup function " of adapting to network environment A, if be provided with the hardware unit member of " thering is input/output function and table lookup function " in the first component base of the described hardware corresponding to network environment A, by driving function, call this hardware unit member, and then generate object member.
The command information that user sends adopts unified control information consensus standard, exchanges data carrying standard, by various abstract adaptation functions are set, makes at user perspective, and it can consider the difference of bottom reconfigurable hardware body.
The quantity of the first component base of described hardware can be for a plurality of, respectively corresponding various common network environments.
Hardware unit member can be to possess several functions, also can only possess a kind of function.In theory, the function more (being also that " granularity " is larger) that hardware unit member comprises, its probability being used is lower, use flow process simpler, otherwise, when the function fewer (being also that " granularity " is less) that hardware unit member comprises, its probability being used is higher, and use procedure is more complicated." granularity " concrete size of hardware unit member can be set according to the actual working condition of network and user's request.
So, when user's transmitting order to lower levels is specified generation object member (hardware component of " having input/output function and table lookup function "), according to its function, " there is input/output function " and " thering is table lookup function ", determine the hardware unit member that there is hardware unit's member of queue function and there is queue management function, then by driving function, call respectively this two hardware unit members, generate the hardware component with input/output function and table lookup function.
By a concrete example, technique scheme is remarked additionally again below: with the fpga chip of altera corp, its driving function is the FPGA driving function that the Quartus instrument of altera corp provides.
