Embodiment
In order to make the object of the invention, technical scheme and advantage clearer,, the present invention is further elaborated below in conjunction with accompanying drawing and embodiment.Should be appreciated that specific embodiment described herein only in order to explanation the present invention, and be not used in qualification the present invention.
The present invention is a kind of equipment of realizing multi-functional parallel work-flow to the single-measurement instrument; Comprise microprocessor (MCU), field programmable gate array (FPGA) chip, LCD display, communication interface, it is characterized in that: also comprise multi-functional parallel work-flow software platform: can realize functions such as oscillograph, multimeter, AWG, audio analysis device; Described fpga chip is responsible for accomplishing high speed processing and work of treatment in real time; Said MCU is responsible for not having the algorithm of real-time requirement.
The said equipment choosing EP3C40 type fpga chip of realizing multi-functional parallel work-flow to the single-measurement instrument; The MCU dominant frequency of said equipment choosing is up to 400MHz.
Saidly realize the use that can walk abreast of oscillograph, multimeter, AWG, the audio analysis device function of the equipment of multi-functional parallel work-flow, also can use separately to the single-measurement instrument.
To the task of multi-functional parallel work-flow, concrete work of treatment is assigned as: FPGA is responsible in the process of integration test accomplishing that high-speed data storage, high-speed data are synthetic, the waveform imaging processing, show functions such as stack and wave form analysis.Resource consumption is as shown in the table substantially to realize the required FPGA of these functions:
The EP3C40 type FPGA that this equipment is selected for use has very rich in natural resources; Comprise the logical block of 39.6K, the storer of 126Kb, 126 multipliers, 4 phaselocked loops and 20 global clock networks, can find out that in conjunction with going up table this FPGA satisfies the demand of instrument fully.
MCU is the main functions such as GUI processing, multimeter signal Processing, Audio Signal Processing and data storage of accomplishing in the process of integration test.Wherein GUI processing operations amount is very little and occur over just and need the man-machine interaction occasion, and CPU usage is very low; The multimeter signal Processing do not have real-time to require and algorithm simple, CPU usage is also very low; Audio Processing is then owing to having CPU time and the resource occupation that certain data volume and a large amount of GUI operations (waveform drafting etc.) need be certain.But because Audio Processing do not have the real-time requirement, and the dominant frequency of the MCU that selects for use of this instrument is higher than the demand of various tests far away up to 400MHz.Even therefore conservative estimation all functions standard-sized sheet, CPU usage also can not surpass 10%.
Can find out in conjunction with above explanation; Why this equipment can realize comprehensive parallel work-flow; Its main cause is that all need high speed processing and the work of handling in real time even comprise analysis of spectrum and work such as waveform demonstration is accomplished by high performance FPGA, and MCU only need be responsible for not having the flexible and changeable algorithm of real-time requirement.
The course of work of FPGA and MCU when being illustrated in figure 1 as this equipment as the oscillograph function.
Concerning the oscillograph function, the maximum extreme case of its treatment capacity is to use high sampling rate continuous sampling, storage, demonstration, and carries out waveform interpolation, analysis of spectrum and cursor simultaneously and measure.
Oscillographic realization is divided into sampling, imaging, wave form analysis, demonstration stack and GUI and handles four major parts.Wherein, Sampling process will be adopted into the waveform storer from the data of ADC; Imaging process is read Wave data; Carry out it being mapped in the imaging storer after the interpolation, the wave form analysis process is carried out suitable conversion (like FFT) and is recorded the waveform correlation parameter waveform, shows that the snapshot that additive process will form images in the storer directly is sent to LCD.More than three processes all inner parallel completion of FPGA.What MCU was responsible for only is that basic GUI handles: respond the alternative events from keyboard, mouse, regulating wheel and touch-screen, and the corresponding registers of FPGA is set.
The course of work of FPGA and MCU when being illustrated in figure 2 as this equipment as the multimeter function.
Concerning the multimeter function, the maximum extreme case of its treatment capacity is to carry out parameter measurement, data operation and record.
Because multimeter does not have real-time requirement, therefore the groundwork of this moment is accomplished by MCU, comprises the access of adc data, the processing of data and the storage of data, and GUI handles simultaneously also needs to be accomplished by MCU.The work of FPGA only is to produce suitable pumping signal to get final product.
The course of work of FPGA and MCU when being illustrated in figure 3 as this equipment as the AWG function.
The realization of AWG function is taken as the leading factor with FPGA.FPGA includes digital synthesizer and wave memorizer, the signal output of this combination results variable frequency.Waveform to be taken place leaves in the internal memory of MCU, passes the wave memorizer in the FPGA by MCU when need producing.GUI handles simultaneously also needs to be accomplished by MCU.
The course of work of FPGA and MCU when being illustrated in figure 4 as this equipment as the audio analysis function.
Visible by Fig. 4, the repertoire of audio-frequency test is realized by MCU, comprises that sampling, record, time-domain analysis, frequency-domain analysis, data storage and the GUI of audio-frequency information handles.
