Generally, in data collecting system, the conversion of data and transmission are realizing by the control to analog-digital converter
, but for high-speed data acquistion system, this method has larger limitation, because high-speed a/d sets up stable work shape
State needs considerable time, and the working condition for frequently changing A/D can affect certainty of measurement, or even cause distorted signals, modulus
The sequencing contro of transducer AD9240 is different with traditional A/D, fully relies on clock control sampling, conversion and data defeated
Go out, start sample conversion in the rising edge of first clock, when the 4th rising edge clock arrives, data will appear in D1～D14
On port, from being powered, analog-digital converter is in running order all the time, and data are not stopped to change for present system, with
The bit error rate is reduced, sampling precision is improved.In the present invention, it is 0～5V's that camera module A and camera module B is sampled signal

All kinds memorizer, such as single port RAM, dual port RAM and synchronization fifo.Jing thinks that FIFO is more suitable for A/D samplings
The memorizer of data high-speed write.Just as data pipe, data are flowed into FIFO memory from one of pipeline, from other end
Flow out, the data being introduced into first flow out.FIFO zero-address lines with 2 sets of data lines, can be in its one end write operation another
End carries out read operation, and order is mobile wherein for data, so as to reach very high transmission speed and efficiency, and due to eliminating address
Line, is conducive to pcb board to connect up.When constituting high-speed a/d sampling caching using FIFO, due to conversion speed comparatively fast, if directly will
It is in data Cun Chudao FIFO after ADC samplings, very strict to sequential configuration requirement, if both sequential relationship mismatees,
Data storage error will occur or fall number, using FPGA can easily control sequential and data transfer, simply and reliably
Realize sampling and store.
The present invention utilizes 2 duplicate FIFO of FPGA fabric, and 2 road A/D change datas are respectively fed to 2 FIFO
In, caching and the transmission of dual pathways sampled data are realized, it is same clock source that in design, A/D change over clocks and FIFO write clock,
From upper electricity, A/D and clock circuit are constantly in working condition, ceaselessly carry out the conversion of data, but whether data are written to
In FIFO, determined by the write enable signal of FIFO, when controller send write enable signal it is effective when, change data could be stored
To in FIFO.The output of A/D change datas and change over clock have certain phase contrast, inside FPGA, can pass through time delay or when
Clock manager is meeting setup time and retention time, it is ensured that data are transferred in FIFO with not losing code, the effect of FPGA except
Construction FIFO is outer to realize data channel multiplexing, is also used as coprocessor and is controlled to carry out some simply efficiently by controller
Data prediction (such as interpolation, be averaged, FIR filtering etc.), with reduce controller process data volume.
