Embodiment
Describe the present invention with reference to the accompanying drawings in detail:
One-piece construction figure as shown in Figure 1 based on embryo's electronic system configurations storer of shift register.In the structure of this embryo's electronic system configurations storer, configuration memory cell becomes ranks to arrange.Suppose to have embryo's electronic system of the capable n row of m embryo's electronic cell, the config memory of embryo's electronic cell of each row all links to each other with delegation's right side cell config memory with it, and the cell config memory of each every trade tail links to each other with the first config memory of the row of next line, the config memory of last embryo's electronic cell of last column of embryo's electronic system links to each other with the config memory of first embryo's electronic cell of first row, the disconnection that can select these tie points by many groups Port Multiplier be connected etc.
Embryo's electronic system that the memory construction that designs based on the present invention realizes, the loading of its configuration data can be very flexible, mainly contains parallel and two kinds of patterns of serial.Under serial mode, the config memory of whole embryo's electronic system just is equivalent to a bigger shift register chain, and data move in turn from input end, finishes until whole embryo's electronic system configurations.Under parallel schema, can select multiple parallel bit wide, each forms an independent passage, wherein the configuration of each passage be operated in serial mode under identical, be independent parallel between the passage.These two kinds of methods can be selected configuration mode flexibly according to the needs of design, realize that configuration data is quick-downloading.Except these two kinds of patterns, can also realize as dynamic restructuring as required etc., realize individual cells or select the cell in zone to carry out online data and download.
The config memory of whole embryo's electronic system links together, and forms the structure of a chain type.
Fig. 2 is the internal circuit configuration synoptic diagram of the configuration memory units of design, and config memory has three shift register CR1, CR2 and CREG.The content of storer is the configuration DNA data of current cell among the register CREG, has represented the performed function of this cell.The 3rd shift register CREG directly is connected with logic function module LB and switch module SB, without any need for decoding logic circuit.NIG, SIG are the configuration DNA data input signal line of two different directions, and SOG, NOG are the configuration DNA data output signal line of two different directions.SG1 and SG2 are the path gauge tap of gene input and output among the figure, embryo's electronic cell is under unactivated state (such as " transparent " state or " free time " state that is not used), can config memory be included in the configuration chain by SG1 and SG2 are set, power consumption can be reduced on the one hand, the speed and the efficient of configuration can be improved on the other hand.SR1, SR2, four alternative selector switchs of SR3, SR4 are controlled the connection status of the input and output of the first shift register CR1 and the second shift register CR2, control by being provided with of four values and select signal to input or output groups of configuration registers.PL1 and PL2 are two Loading Control signals, can trigger by the fault detect self-repair circuit of right cell self, also can trigger, be used for controlling the loaded in parallel of the 3rd shift register CREG or the second shift register CR2 register configuration data by overall control signal.
In the time of configuration, setting according to multi-way switch, data serial is moved among the first shift register CR1 or the second shift register CR2 one by one, after treating all configuration datas that need all serial downloading in the register of embryo's electronic cell of appointment, under the control of PL1 of overall signal or PL2, configuration data is loaded among the 3rd shift register CREG.Under the situation that does not influence embryo's electronic system operate as normal, loading first shift register CR1 that can online serial again and the configuration data of the second shift register CR2, finish the dynamic restructuring of embryo's electronic system, promptly when operation, realize the embryo's electronic system function or the operations such as quick switching of partial function.The mechanism of the selfreparing of embryo's electronics also realizes by this method, after embryo's electronic system configurations is finished, content among the 3rd shift register CREG is under the control of the PL2 of overall signal, loaded in parallel is in the second shift register CR2, move to previous cell by the second shift register CR2 then, promptly the gene data of embryo's electronic cell self is loaded among the first shift register CR1 in the configuration register of flanking cell automatically with delegation.When certain cell breaks down, realize the quick realization of embryo's electronic cell selfreparing by reconfiguration unit.
Dynamic restructuring has adopted the reconfiguration unit of cell interior to finish, but the reconfiguration unit of cell interior is used for the fault selfreparing, by cell fault error signal triggering.The reconstruct that function is switched is not identical with the reconstruct of fault selfreparing, and embryo's electronic cell placement-and-routing again finishes new function in the reconstruct of function switching.If the fault-tolerance approach that adopts cell to remove is carried out fault selfreparing reconstruct, also need to consider behind the cell reconstitution annexation with other cell, the cell annexation changes after the fault selfreparing, need to adopt extra switch switch unit to realize, will trigger the switch unit in the restructuring procedure of fault selfreparing and switch connection line.
Fig. 3 is the coordinate Calculation module of the embryo's electronic cell among the present invention.Realize dynamic restructuring and fault selfreparing with dynamic restructuring dr_cfg signal and cell fault error signal respectively, the error signal is from the failure diagnosis unit of cell interior or the error signal of flanking cell, and in restructuring procedure, trigger the switch unit of embryo's electronic cell, and dr_cfg is from the dr_cfg signal of control signal or flanking cell, and it is constant that the switch unit keeps original state in restructuring procedure, promptly do not change the annexation between embryo's electronic cell.
Fig. 4 is the address decoding circuitry of improved embryo's electronic cell, and except WEG and position selection NEG were selected in word select, an EEG and a position selection SEG registers group were selected in the word select that has increased reverse selection among the figure.Select the rectangular area of module by word line and bit line registers group, select unwanted rectangular area in the module by reverse word line and direction bit line then, thereby realize a polygonal module, shine upon shape flexibly for application circuit provides, reach the purpose that improves embryo's electronic cell resource utilization.
The foregoing description does not limit the present invention in any form, and all technical schemes that mode obtained of taking to be equal to replacement or equivalent transformation all drop in protection scope of the present invention.
