Description
Technical field
The present invention relates to a kind of programmable device and programmed method thereof, relate in particular to a kind of universal programmer and programmed method thereof.
Background technology
In the exploitation and design of hardware system, the data read-write operation that chip is carried out is called as chip programming (Program).For example, adopt the various systems of single-chip microcomputer (Single Processor) control need be with the single-chip microcomputer of the control program programming of exploitation; The chip that is used for stores configuration data is programmed; To being used for field programmable gate array element (Field Programmable Gate ArrayDevices, FPGA Devices) or complex programmable logic element (Complex Programmable LogicDevices, programming CPLD) of IC design.Though for each element, chip maker all can provide corresponding program means, also press for a kind of programming device that can support the number of different types chip simultaneously, thereby universal programmer becomes first-selection.
Please refer to Fig. 1, is the block diagram of the universal programmer of prior art shown in the figure.As shown in the figure, the program of programmable device is supported in computing machine 10 operations, and by main control chip 11 communications of control interface (as serial ports, parallel port or USB) with programmable device, corresponding operating is resolved and carried out in the order of 11 pairs of receptions of main control chip.For example, receive the sequential interface I by main control chip 11 behind the program command of objective chip I12 is produced control timing, finish programming objective chip I12.Equally, can finish programming by similar operations to objective chip II13.On stream, when need test the program of main control chip 11, when revising, activate an integration development environment (IntegratedDevelopment Environment) software by computing machine 10 and connect download interface 14, will be programmed into main control chip 11.After product development finished, any change can not take place in the program of main control chip 11, that is, the employed programmable device of user does not have download interface 14.Therefore, when the user need increase programming to a newtype chip, or change a more programmable device of high standard, or require manufacturer that the program of main control chip 11 is upgraded even change hardware circuit.Above-mentioned dual mode is all very inconvenient, also is unfavorable for very much the renewal upgrading of product.
At present, there is a kind of improvement to above-mentioned universal programmer.Please refer to Fig. 2, is the block diagram of the universal programmer after improving shown in the figure.As shown in the figure, universal programmer 20 comprise a main control chip 21, field programmable gate array element 22 and programmable read only memory 23 (Programmable Read Only Memory, PROM).It is more convenient that but scene program gate array device can offer Hardware Design, and the configuration of modification or upgrading hardware system only needs can realize by change software, greatly reduced cost of development and risk.After computing machine 10 transmission orders were to universal programmer 20, the main control chip 21 of universal programmer 20 received and resolve command, and according to the command execution corresponding operating of resolving.When being resolved to program command to objective chip I12 as main control chip 21, its control field programmable gate array element 22 produces control timing and finishes programming to objective chip I12.Wherein, field programmable gate array element 22 comprises generation sequential functional programs code, and this program code storage is in programmable read only memory 23.When programmable device 20 was connected to power supply, the configuration mode that powers on of field programmable gate array element 22 (Configuration Mode) imported field programmable gate array element 22 with the program code in the programmable read only memory 23.Therefore, this mode has overcome the shortcoming that upgrading products need be made amendment to circuit, only needs amended program code is burnt to new programmable read only memory to substitute upgrading and the renewal that original programmable read only memory can realize product.Yet this mode need be finished by manufacturer equally, brings very big inconvenience to the user.And, adopt programmable read only memory to have brought hidden danger also for the security of program code, because as long as the program code in the programmable read only memory can be read or copied portion and be placed in other field programmable gate array element, other field programmable gate array element has also just possessed identical programing function, therefore has great potential safety hazard.
In addition, all there are the characteristics to the chip programming locality in above-mentioned universal programmer, be that programming device can only be changed behind the chip control program on the operational computations machine by operating personnel again and realizes programming operation to chip, can not realize purpose the chip programming Long-distance Control.But along with production-scale continuous expansion, need the programmed chips value volume and range of product more and more, the manual programming of finishing chip of simple dependence has shortcomings such as efficient is low, error rate height, therefore need realize control by automatic equipment, thereby finish programming the production line chip to universal programmer.
Summary of the invention
In order to solve above-mentioned the problems of the prior art and defective, the object of the present invention is to provide a kind of universal programmer and programmed method thereof, be used for a plurality of dissimilar objective chip are programmed.
A kind of universal programmer provided by the present invention comprises: network interface is used for seeing through the network equipment (as, router) and carries out communication with remote computer; Main control chip, be used to store the program code information of each objective chip and the driver of an Ethernet chip, also resolve the data that receive by the data that network interface receiving remote computing machine sends, when being upgrading data packet, the data of resolving store the program code information of a newtype objective chip according to this upgrading data packet, when the data of resolving are program command, send the program code of corresponding objective chip and control programming to objective chip according to order; And programmable element, be used to receive the program code of the objective chip that main control chip writes, and produce control timing according to the control of main control chip and finish programming objective chip.
