Brief description of the drawings

Fig. 1 is a kind of soft hardened system principle framework figure of space flight based on commercial goods shelf productses.

Embodiment

The present invention will be further described below in conjunction with the accompanying drawings.

As shown in figure 1, a kind of soft hardened system of space flight based on commercial goods shelf productses, including fpga chip, dsp chip, Fpga chip, the first watchdog chip, the second watchdog chip, wherein fpga chip include image forwarding module and fpga chip Monitoring module.

Dsp chip includes image compression module and dsp chip monitoring module, and fpga chip is each only with dsp chip Vertical operation, image forwarding module receive the view data that extraneous camera is sent, and view data is carried out subpackage processing transmit to The image compression module of dsp chip, the image compression module of dsp chip are transferred to FPGA after raw image data is compressed The image forwarding module of chip, image forwarding module again export the view data of compression；In fpga chip, image forwarding mould The time sequence status of itself is fed back to fpga chip monitoring module, fpga chip state prison by block in real time in the process of running This timing is received transmission view data sequential with the FPGA built in fpga chip monitoring module and contrasted by control module, when When state meets to require, i.e., produced to dsp chip transmission and feed dog instruction, DSP monitoring modules produce hello dog trigger signal and given First watchdog chip, the first watchdog chip do not produce reset trigger signal；Production is not sent then when state is unsatisfactory for requiring Raw to feed dog instruction, DSP monitoring modules, which do not produce then, feeds dog trigger signal, and the first watchdog chip can then produce FPGA resets Trigger signal resets FPGA, can now ensure the sequential stable operation of fpga chip.

The image compression module of dsp chip receives raw image data, carries out the compression of images of specific format, this compressed package Include H.264 compression and JPEG compression, the image forwarding module that the data after compression are sent to FPGA after the completion of compression and carry out figure As data output；In dsp chip, the sequential of image compression module operationally Real-time Feedback itself condensing routine is to DSP's DSP built in this timing and DSP monitoring modules is received and is sent picture number by monitoring module, DSP monitoring modules It is compared according to sequential, both sent to produce to fpga chip when state meets to require and feed dog instruction, fpga chip condition monitoring Module produces hello dog trigger signal and gives the second watchdog chip, and the second watchdog chip does not produce reset trigger signal；Work as state Not sending generation when being unsatisfactory for requiring then and feed dog instruction, fpga chip monitoring module, which does not produce then, feeds dog trigger signal, the Two watchdog chips, which can then produce DSP reset trigger signals, resets DSP, can now ensure that the sequential of dsp chip is stable and transport OK, wherein, it is that image forwarding module receives and sent view data in fpga chip that FPGA, which is received and sent view data sequential, Order and time, it is that image compression module receives, compresses and sent image in dsp chip that DSP, which is received and sent view data sequential, The order of data and time.
