Background technology

Field programmable gate array FPGA (Field Programmable Gate Array), it is the product that further develops on the basis of programming devices such as PAL, GAL, EPLD.The use of FPGA is very flexible, and inner available resources is abundant, can produce different circuit functions with a slice FPGA by different designs.FPGA has obtained extensive use in various fields such as communication, data processing, network, instrument, Industry Control, LED, military affairs and Aero-Space, for example in the core technology of modern LED display is used, has just adopted fpga chip in a large number.

At present, FPGA adopts fixed logic in the MCU system, both when exploitation, finished the fpga logic design, generate the FPGA configuration data file, and the FPGA configuration data file write in the FPGA hardware, FPGA automatic or passive configuration application circuit logic when powering on configuration during actual the use is used ARM or single-chip microcomputer configuration FPGA internal circuit logic in the certain applications.Hardware logic exploitation and embedded software developing were relatively independent during these were used, though in the application of single-chip microcomputer configuration FPGA circuit logic, can make the different circuit module of FPGA cell configuration, the actual application that this dynamic-configuration FPGA hardware of employing is also arranged, but hardware logic is not with the software development language combination, and the fpga logic circuit can dynamically not realized the renewal configuration of hardware logic in real time according to the software systems operation.

The utility model content

The purpose of this utility model is, a kind of FPGA of realization is provided the system of real-time dynamic-configuration.

The technical solution of the utility model: a kind of system that realizes the real-time dynamic-configuration of FPGA, described system comprises fpga chip, fpga chip is connected with the MCU system that it is compiled in real time.

In the system of the above-mentioned real-time dynamic-configuration of realization FPGA, described MCU system also connects the structural array conversion equipment.

In the system of the real-time dynamic-configuration of aforesaid realization FPGA, described MCU system is provided with the storage device of the application data configuration file that stores the MCU system.

In the system of the real-time dynamic-configuration of aforesaid realization FPGA, described storage device comprises program storage device and dynamic storage device.

In the system of the real-time dynamic-configuration of aforesaid realization FPGA, described MCU system also is connected with the display unit of the application data configuration file of the configuration file correspondence that demonstration loading.

Compared with prior art, the utility model adopts the MCU system for field that FPGA is carried out real-time dynamic-configuration by the improvement to the MCU system, has obtained following beneficial effect.

The utility model can read or write application data (being application software) by the MCU system so that the FPGA that encapsulation is finished does not need independent upgrading, again application data is loaded on fpga chip, realizes the real-time dynamic-configuration of FPGA; Therefore, the FPGA that the utility model not only can make encapsulation finish has realized different functions, and the recycling of encapsulation class FPGA hardware, greatly reduce operating cost, improved operating efficiency, simultaneously a plurality of application systems of MCU system are reused same sealing class FPGA hardware and have also been accelerated the system design progress, have saved the development time.The utility model also comprises the structural array conversion, promptly the structural array according to the configuration data file of fpga chip converts the structural array that adapts with embedded system to, makes the MCU system of different structure array can compile out the configuration file of same FPGA hardware.
