Specific embodiment
As shown in Figure 1, a kind of infrared imaging focuses the visuable debugging method of FPGA system automatically, this method includes following
Step:
Step S1, the client/server communication for establishing MATLAB and ModelSim links
Interface has been reserved to ModelSim simulation software in the ISE Integrated Development Environment of Xilinx company, has passed through this
Interface can directly initiate ModelSim tool from ISE the integration environment and be emulated, so that it may reach ISE the integration environment and
The purpose of ModelSim implement work.MATLAB also has the associative simulation interface of a connection ModelSim, this interface
A quick duplex channel is provided between.It can be by the Tool integration of MathWorks to electronics by the interface
FPGA exploitation and emulation are carried out in the workflow of design automation (EDA) tool.
The associative simulation environment of ModelSim and MATLAB depends on the connection type between them, and this connection type is
A kind of relationship of client/server (client/server): MATLAB is as server, and ModelSim is then client, such as
Shown in Fig. 2.After being mounted with MATLAB, Simulink and ModelSim software, need through MATLAB script with interactive or
The mode of order line programming configures ModelSim, to establish the client/server communication of MATLAB and ModelSim
Then link combines again and carries out the associative simulation that infrared imaging focuses automatically.Carrying out client configuration to ModelSim is to pass through
MATLAB function setupmodelsim realizes, a function registration MATLAB system relevant to the connection of ModelSim emulator
Arrange Tcl order, and ModelSim installation directory create ModelSimTclFunctionsForMATL in tcl subdirectory
AB.tcl file is to save these Tcl orders.In addition, also needing the specified mounted software version of ModelSim and executable file
As the default emulator for executing vsim order.
(1) ModelSim is configured with interactive mode
With interactive mode configuration ModelSim firstly the need of the input function title under the command prompt of MATLAB
Setupmodelsim selects the installation for needing to be linked with MATLAB according to the requirement of installation script with user
ModelSim software version.At this point, if user's selection shows all version lists for having installed ModelSim software,
Setupmodelsim function can search for all mounted ModelSim software versions and user is allowed to select one of them；If with
Family needs voluntarily to specify mounted ModelSim version, then script will prompt user's input to install ModelSim software
The path of executable file modelsim.exe or vsim.exe.If setupmodelsim function successfully modifies installation file
It exits；It is linked if ModelSim software had been configured with MATLAB, can be shown in ModelSim installation directory tcl
The information of the ModelSimTclFunctionsForMATLAB.tcl file created in subdirectory, and allow user selection be
No covering tcl file.For example, being followed the steps below in present example with interactive mode configuration ModelSim needs:
1. input function " setupmodelsim " or " setupmodelsim under the command prompt of MATLAB console
(' action', ' install') ", then MATLAB, which is returned, requires user to select the installation for needing to be linked with MATLAB
The information of ModelSim version: " Identify the ModelSim installation to be configured for
MATLAB and Simulink.Do you want setupmodelsim to locate installed ModelSim
Executables [y]/n? "；
2. the specified ModelSim version of installation linked with MATLAB.It has been installed if user wants voluntarily to specify
The path of ModelSim version please input " n ".At this point, MATLAB, which returns to prompt user, inputs ModelSim executable file
The information in the path modelsim.exe or vsim.exe: " Please enter the path to your ModelSim
Executable file (modelsim.exe or vsim.exe): " input in this example: " D: modelsim win32 " i.e.
It can.If the user desired that positioning and showing all lists for having installed version, then input " y " or press " enter " key.Then
Setupmodelsim function can search for mounted all ModelSim versions, and return to relevant information in MATLAB.
3. according to user step 2. in response, input one of the following contents: (a) executable ModelSim or vsim
Full path；(b) installing the numerical listing (0,1 ...) of identifier, then setupmodelsim function modification installation file exists
MATLAB returns to message " ModelSim successfully configured for MATLAB and Simulink ", then
It exits.
ModelSim installation if it is MATLAB and Simulink link configuration has been modified, and will appear corresponding
Message is verified, if user, which inputs " y ", covers the tcl file, setupmodelsim will cover this document, and then display disappears
Breath: " ModelSim successfully configured for MATLAB and Simulink "；Otherwise, if user is defeated
Enter " n " to show afterwards message " ModelSim configuration not updated forMATLAB and Simulink ", and
It is exited in the case where not modifying file.
(2) ModelSim is configured with command mode
With command mode configuration ModelSim firstly the need of use " action " attribute and set property for
" install " calls function setupmodelsim starting configuration, then uses " vsimdir " attribute and sets property to need
The path of the executable file modelsim.exe or vsim.exe that have installed ModelSim to be linked with MATLAB
" pathname " is to select the ModelSim version of installation linked with MATLAB.If desired current ModelSim version pair is unloaded
The link of MATLAB configures, then uses " action " attribute and set property and call function for " uninstall "
setupmodelsim('action','uninstall')。
For example, configuring ModelSim in present example with command mode, it is only necessary to be inputted in MATLAB console
Order " setupmodelsim (' action', ' install') " and " setupmodelsim (' vsimdir', ' D:
Modelsim win32') ".
Step S2. works out the MATLAB function as server
MATLAB function as server will wait the ModelSim emulator sending to be received from as client
Service request, after receiving a request, MATLAB server functions will establish and ModelSim emulator between one
Then a communication connection activates a corresponding MATLAB to handle function, VHDL module to be measured is input to ModelSim and is imitated
True device simultaneously shows the simulation data result of return progress mathematical computations, Numerical Validation analysis and image/video, recycles communication
Operation schematic diagram is as shown in Figure 3.
Establishment MATLAB server functions are firstly the need of doing following some necessary be pre-configured with:
1. specified MATLAB server functions title.For example, MATLAB server functions name is arranged in present example
Referred to as test_sync, form are as follows: function [iport, tnext]=test_sync (oport, tnow, portinfo)；Its
In, iport and tnext are output parameter, and iport is input port name, and tnext is the readjustment time of MATLAB function；
Oport, tnow and portinfo are input parameter, and oport is output port name, and tnow is current allocating time, portinfo
It is port information.
For example, the port signal that input port iport is used in present example includes: the video of infrared imaging system
Data transfer clock signal (15MHz) iport.clk15, global system reset signal iport.odd and eight video datas
Signal iport.tv；The port signal that output port oport is used includes: IR video stream output and its marking signal
Oport.tvosign and oport.tvstream_out, the output of autofocus area image data and its marking signal
Oport.fzsign and oport.focuszone, the output of focal zone pattern mask filtering data and its marking signal
Oport.flsign and oport.filter_out, focal zone calculate gained focusing evaluation Value Data output and its marking signal
Oport.fesign and oport.focus_eval.
2. initializing the output parameter of MATLAB server functions.In the beginning of function, output parameter iport and tnext
It must be initialized as null value.For example, being arranged in present example in the beginning of test_sync function: " iport=struct
()；Tnext=[]；".
3. the global variable and local variable of MATLAB is arranged.For example, a global variable is arranged in present example
(global) it is used as benchmark sequential counter cn, is counted to the rising edge to data transfer clock, the global variable meeting
It always exists in memory and is used for all m functions；It is arranged five for storing and transmitting visualization window display properties parameter
Local variable ud, vd, wd, ld and md, these persistent local variables stated in server functions test_sync also will
Can always exist in memory, but unlike their the function test_sync that can only be defined use, can prevent in this way by
Other functions or other orders are changed.Wherein, ud is used to record the infrared focusing video figure of the actual acquisition as test source
The display properties of picture；Vd is used to record the display properties of focal zone image；Wd is for recording the filtering of focal zone spatial mask
Export the display properties of image；Ld is used to record the display properties of output focusing evaluation of estimate curve；Md is used as image register
In the property parameters of complete excitation image of the storage comprising comprehensive blanking signal.Above-mentioned set global and local variable only has
It can just be removed when m file is changed or is removed from memory.
4. controlling the readjustment time tnext of MATLAB server functions.Adjusting back time tnext should adjust always greater than current
With time tnow.For example, tnext=tnow+5e-9 is arranged in present example, show that it was 5 nanoseconds that the clock cycle, which is arranged,
(5e-9 seconds), the practical readjustment time of server functions were 2.5 nanoseconds.
5. obtaining and application port information.The format of port information are as follows: portinfo.field1.field2.field3,
Wherein field1 be input, output, two-way or unit (in out inout tscale)；Field2 is port name
(portname)；Field3 be the port types such as left end, right end, digit or label (right left size label).
6. carrying out the conversion of data type between MATLAB, VHDL and ModelSim.These conversions include from ModelSim
Several key datas received to MATLAB conversion, as shown in table 1；The several main of ModelSim is returned to from MATLAB
Data type conversion, as shown in table 2.In step S2 of the invention, to focus the visual of FPGA module automatically to infrared system
Change emulates and the concrete configuration of the MATLAB server functions of establishment includes following sub-step (as shown in Figure 4):
Transfer function of several main data types that table 1 is received from ModelSim to MATLAB
| MATLAB | It converts from the received response signal of ModelSim |
| double | double(idata) |
| unsigned integer | bin2dec(oport.***) |
| signed integer | bin2dec(oport.***)-2^length(oport.***) |
| Test port value | All (oport.***=='1'| oport.***=='0') |
The transfer function of main data types of the table 2 from MATLAB back to ModelSim
| ModelSim | Convert the pumping signal sent from MATLAB |
| Character array (standard logic vector or position) | Iport.***=dec2bin (* * *, n) |
System parameter when sub-step S201 initialization is called for the first time
When first time Calling MATLAB server functions, it is necessary to global variable and part to input port user setting
Variable carries out being initialized to subsequent use.In present example, if current allocating time tnow is less than 1 nanosecond (1e-9 seconds)
Or the number of input parameter be 3 (tnow < 1e-9 | nargin==3) in the case where be considered as first time Calling MATLAB server
Function, concrete operations include: 1. three signals on initialization input mouth iport: global system reset signal is initialized
It is reset, video data transmission clock signal is initialized as low flat with open system for Gao Ping (iport.odd='1')
(iport.clk15='0'), eight video data signals are initialized as zero (iport.tv='00000000')；②
Initializing as the global variable cn of benchmark sequential counter is 0；3. the part for initializing original infrared imaging output image becomes
Measure md.Md is a structure variable, is mainly used to store and operate the infrared focusing video figure as ModelSim pumping signal
Picture.Md is made of seven fields: md.FOV is visual field class label, if the current infrared focusing video as test source is wide visual field
Image is then initialized as md.FOV='WFOV', be then initialized as narrow visual field ' NFOV'；Md.field is picture field label, just
Begin to turn to 1 expression as test source to be first focusing image；Md.size is picture size, is initialized as test source images
Size (such as 768 × 576)；Md.InFigreg is image register, is initialized to a uint8 type of md.size size
Matrix, for storing focusing image of the width read in by MATLAB as the infrared imaging system actual acquisition of test source；
Md.clock is the pixel data clock drive as test source, is initialized to 1；Md.i and md.j is current transmission pixel number
According to shift counter, be initialized to 1 and 0 respectively.
Sub-step S202 generates the pumping signal wait emulate automatic focus module
Reading in test source video image and generating pumping signal for ModelSim is establishment MATLAB server functions (step
S2 most crucial sub-step in), as shown in Figure 5.In present example, mainly have for the pumping signal that ModelSim is provided:
Video data transmission clock signal, global system reset signal and three kinds of video data signal of eight.
Firstly, carrying out detection to local variable md.clock when each invoking server function and passing its reverse phase to generate
Defeated clock signal iport.clk15.For example, when detecting that md.clock=0 is arranged then to generate a clock in md.field=1
Failing edge, it is on the contrary then generate rising edge clock；Input end of clock mouth iport.clk15 is output to by transfer function dec2bin
=dec2bin (md.clock).
Then, pixel shift counting is carried out in the rising edge of each clock, and in " field effective period " and " row effectively week
One infrared focusing video image is read in phase " as test source.For example, reading in point of the width from certain infrared system actual acquisition
The manual focusing video image that resolution is 768 × 576 accounts for the ratio in field (row) period effective period by calculating field (row), obtains
It is counted within 1~313 (field duration) with column to the count range for the shift counter for transmitting pixel data: control linage-counter md.i
Number device md.j counts clock md.clock rising edge within 1~960 (row period), when a md.i=313 (field duration knot
Beam) and when md.j=960 (a row end cycle), use imread order to read in as the infrared focusing image of test source,
And store field (row) valid interval (25:312,1:768) for arriving image register md.InFigreg.Due to the tune of actual acquisition
Burnt image be by " visual field type " and " field number " name file store, therefore read in when need by md.FOV with
Md.field specified attribute value navigates to corresponding folder address.
Finally, each rising edge clock within the field duration closes system resetting, current shift count device is posted in image
The pixel data specified in storage is output to eight video input ports by conversion.For example, when linage-counter md.i 1~
Global system reset signal is set to low flat (iport.odd='0') to close system resetting when 313 (field duration) are interior；With turn
The md.i and md.j pixel positioned in image register md.InFigreg is converted to 8 binary systems by exchange the letters number dec2bin
Number, and it is output to video input port iport.tv=dec2bin (md.InFigreg (md.i, md.j), 8).
