Please also refer to Fig. 4 and Fig. 5, the programmable counter 211-21N among each micro controller 201-20N can corresponding separately at least one breakpoint address 301-30M; N needn't equate that with M meaning is that each programmable counter can correspondingly surpass a breakpoint address, or a plurality of programmable counter can corresponding same breakpoint address.Single-chip microcomputer program designer can assign instruction by 22 pairs of single-chip micro computers of full duplex connectivity port interface simulator 24 from personal computer 20, after this instruction is received by analog controller 26, by one or several breakpoint activation switches 34 corresponding breakpoint of programmable counter 211-21N of one of activation or several multiple micro controller respectively, the programmable counter that breakpoint is enabled can compare with corresponding breakpoint address 301-30M constantly, when both are identical, analog controller 26 each micro controller of can stopping at once; Otherwise, both each micro controller of more can not stopping then, this breakpoint activation switch 34 carries out the breakpoint activation in order to the programmable counter 211-21N that whether sets multiple micro controller 200, and analog controller 26 can be set these breakpoint activation switches 34; Analog controller 26 can be when program be carried out breakpoint address 301-30M and all micro controller and is stopped, will be at this breakpoint address 301-30M place, all of multiple micro controller 200 or the state of a part of micro controller 201-20N, the development environment that utilizes full duplex connectivity port interface 22 to be transferred on the personal computer 20.
Above framework, it than detail circuits embodiment as shown in Figure 6A, in single-chip micro computer simulator 24, be provided with breakpoint system energy buffer 36 and multiple micro controller executing state buffer 42, in addition and in analog controller 26, be provided with comparator circuit 38, it can be made of a plurality of comparer 381-38M, for making comparisons with M breakpoint.Must explanation be, this only may implement kenel for wherein a kind of, for example, more must not the finishing of breakpoint with hardware comparison circuit, and certainly also the available software mode reach; Again, when reaching with hardware, the number of comparer also may not be identical with the breakpoint number, can make it become the many-to-many relationship that number does not wait by multitask mode, this be all that those skilled in the art can think easily and.In the embodiment shown in Fig. 6 A, when single-chip micro computer simulator 24 is desired all micro controller of stopping at the breakpoint address 301-30M that sets, and the system state when program carried out this breakpoint address 301-30M, personal computer 20 is given in passback, the action of its inside is: the development environment of personal computer 20 is set the breakpoint address 301-30M of the executive routine correspondence of each micro controller by full duplex connectivity port interface 22 and 26 pairs of program breakpoint Address Registers of analog controller 32, and, development environment is also set breakpoint activation buffer 36, which breakpoint address 301-30M with and relatively the programmable counter 211-21N of micro controller 201-20N to do the breakpoint activation, which is not enabled; Under the activation situation, carry out the breakpoint address 301-30M of this corresponding setting when the program of each micro controller, when the programmable counter 211-21N that comparer 381-38M compares multiple micro controller is identical with the breakpoint address 301-30M of setting, analog controller 26 all micro controller of can stopping, at this moment, the program execution state of each micro controller can be transferred to personal computer 20 by analog controller 26 and full duplex connectivity port interface 22; Simultaneously, one multiple micro controller executing state buffer 42 each micro controller executing states of record are arranged, comprise that present breakpoint address 301-30M is that programmable counter 211-21N by that micro controller is taken place, this information also is back to personal computer 20 via analog controller 26 and full duplex connectivity port interface 22.
Another specific embodiment of the present invention is shown in Fig. 6 B, be with Fig. 6 A difference: each micro controller in the single-chip micro computer simulator 24 is to be performed under the different sequential that stagger mutually, therefore the programmable counter 211-21N in the multiple micro controller 200 is except that can a corresponding separately breakpoint address 301-30M, even can be (as shown in the figure by the corresponding same breakpoint address 301-30M of the programmable counter 211-21N more than two, the programmable counter 212 of micro controller 202 and the programmable counter of micro controller 203 213 common corresponding same breakpoint address 302), under the activation situation, whether the different programmable counter 211-21N more than two in the multiple micro controller 200 can compare at comparer 381-38M with identical breakpoint address 301-30M simultaneously, have any programmable counter 211-21N to carry out the breakpoint address 301-30M that sets to monitor; Because each micro controller is to be performed under the different sequential that stagger mutually, so when each breakpoint takes place, can know by the information of multiple micro controller executing state buffer 42 and to know that this breakpoint is taken place by that programmable counter 211-21N, this information can pass back to personal computer 20 by analog controller 26, what can can't do not triggered by person by the identification breakpoint because of plural programmable counter 211-21N sets identical breakpoint address 301-30M, because of the corresponding same breakpoint address 301-30M of the programmable counter 211-21N more than two is independently behavior separately, and the program of each micro controller is carried out sequential and is staggered, each breakpoint is only triggered by a programmable counter 211-21N, does not have two programmable counter 211-21N at a time point and triggers breakpoint address 301-30M situation simultaneously.
For convenient programmer carries out program trace, according to another part content of the present invention, micro controller state and other important information can be presented on the picture of personal computer in a kind of open-and-shut mode, wherein an example can be with reference to figure 7A-7E.Among Fig. 7 A, what occupy most of position, picture bottom top is a program step display window 501, wherein demonstrates each step (some step is omitted with ellipsis among the figure) of program with linescan method.There is an action window 505 picture bottom below, the action that the display routine designer carried out, and for example from where downloading this program, or the like.Be positioned at right-hand, overlapping bottom window 501 tops of being shown in of picture, it is a general caching device display window 502, wherein show in the tested multiple micro controller, the state of the general caching device of sharing for all micro controller (example is R8-RF as shown in the figure), and wherein also can the display routine execution time (example is TIME as shown in the figure) etc.
The maximum difference of present embodiment and prior art shown in Figure 3 is, a micro controller state display window to change mouth 503 is arranged among Fig. 7 A, wherein show in the multiple micro controller simultaneously, each important parameter state of each micro controller, in a kind of open-and-shut mode, whether wrong with reference to also checking for the programmer.Which belongs to important parameter as for, and visual programmer's demand decides, and only is an example wherein shown in the figure.In detail, in the embodiment of 7A, demonstrate in the micro controller state display window to change mouth 503 and the content numerical value of first micro controller (MCU1) corresponding programs counter (PC1), the content numerical value of totalizer (ACC1), the content numerical value of stack pointer device (SP1) and the content numerical value of flag buffer (Flag1).The content numerical value of flag buffer in fact is the comprehensive numerical value of one group of flag, and the programmer can be in window, and the positive sign of pressing the Flag1 left launches it.The corresponding flag buffer (Flag2) of second micro controller (MCU2) for example, its each Ziqi target content numerical value just launches, wherein for example comprise null value flag (zero flag), overflow flag (overflow flag), carry flag (carry flag) or inferior carry flag (alternativecarry flag) or the like, and outside last arithmetic flag, still may comprise other arithmetic or non-arithmetic flag (representing) with ellipsis.In above parameter of giving an example, the content numerical value of programmable counter is most important parameter, also be under the general situation programmer definitely must reference numerical value.
In fact, each micro controller also may respectively have its special-purpose buffer except that having corresponding programmable counter, totalizer, stack pointer device and flag buffer; For example, first micro controller (MCU1) may have dedicated buffer PA, PAC, PAPH, PAOD, it also can be presented in the micro controller state display window to change mouth 503 certainly, or shown in Fig. 7 A, these dedicated buffer is presented in the general caching device display window 502.Again, when window showed all the elements information inadequately, as shown in the figure, available scroll bar (scroll bar) mode went up drop-down moving for the programmer, to adjust the displaying position of window.
In addition, shown in Fig. 7 B, also general caching device display window 502 and micro controller state display window to change mouth 503 can be integrated into same comprehensive state display window 602, though wherein with each of each micro controller important with minor parameter state, be incorporated in the same window with the content numerical value of general caching device, but can be by launching (pressing positive sign) and fold (pressing negative sign) function, come convenient programmer optionally consult want the numerical value observed; For example among Fig. 7 B, the parameter state of the 3rd micro controller MCU3 and the 4th micro controller MCU4 folds, and the state information of general caching device also can integral body fold, and makes in the window the only remaining state information of wanting the specific micro controller of observing.
In the embodiment of Fig. 7 A and Fig. 7 B, the programmer has configured breakpoint, and for example upper left arrow indication step 34 (reference numbers 510) among the figure is one of breakpoint.Program is ended at this breakpoint location, allows the programmer can check that each numerical value is to carry out debug.But under some application scenario, though the programmer has configured a plurality of breakpoints, but might not wish all to end program at each breakpoint address, for example, the programmer may want to be absorbed in the procedural problem that solves some or a plurality of (but non-whole) micro controller, the step that this moment and these one or more micro controller are irrelevant, that is by the performed step of other micro controller, even run into breakpoint, do not want to end yet.At this kind demand, can be with reference to figure 7C, according to the present invention, a menu can be provided on picture, and this menu can as shown be the window menu 508 of a Pop-up, but can certainly show with other kind of a mode, order button for example is provided above picture, presses drop-down demonstration in back or the like.The programmer can select the micro controller of the debug of wanting on menu, for example in Fig. 7 C, multiple micro controller all has eight micro controller, and the programmer is only interesting to second and the 6th micro controller, so chosen second and the 6th micro controller.
After the selected micro controller, suppose program designer does not change the breakpoint that originally sets, that is the breakpoint that still sets with Fig. 7 A and Fig. 7 B is identical, after starting (or restarting) program this moment, run into and the irrelevant breakpoint of selected micro controller, can skip automatically and can not end, for example in Fig. 7 D, when program starts anew to proceed to step 34 (one of institute's breaking originally), can't pause, but continue to carry out and second or the 6th relevant breakpoint of micro controller, for example just end during arrow indication step 35 (reference numbers 511).
Again, as shown in Fig. 7 D, after the selected micro controller, also can change micro controller state display window to change mouth 503 accordingly automatically, make the state of the selected micro controller of its demonstration.But the state that certainly, also can still show all micro controller.
Above for embodiment, all be to be illustrated, but the present invention is not limited to be applied in the occasion of breakpoint debug at the occasion of utilizing the breakpoint debug, make program progressively carry out the programmer, when carrying out progressively debug, also can use.The embodiment of Fig. 7 A and Fig. 7 B, in the occasion of debug progressively, its emphasis is to show two or more micro controller states on picture simultaneously, checks debug with convenient programmer; The embodiment of Fig. 7 C to Fig. 7 D, in the occasion of debug progressively, its emphasis is to skip and step that selected micro controller is irrelevant.For example the picture of Fig. 7 D can be not set under the situation of any breakpoint, by the programmer by manual mode operation mode, progressively executive routine.At this moment, the programmer whenever controls a step, and program is just down carried out a step back at selected micro controller and paused, but when running into not selected micro controller, then carries out continuously.
Except above-mentioned points, for example with reference to the picture of figure 7E, still can emphasize to show the step relevant, shown in reference numbers 512 with selected micro controller.Certainly, display packing is not limited to add coloring grounding, also can adopt alternate manner, as conversion font or the like.As previously mentioned, in Fig. 7 E, can be to end to be parked in program step 214 (reference numbers 513) because of breakpoint, or because progressively debug and end to be parked in this step.
Again, above Fig. 7 A-7E for embodiment, all be to illustrate, but a plurality of micro controller at multiple micro controller, even be not integrated into a single-chip, also display frame in the same way still belongs within the notion of the present invention.
Below at preferred embodiment the present invention is described, the above only for those skilled in the art are easy to understand content of the present invention, is not to be used for limiting interest field of the present invention.For those skilled in the art, when can in spirit of the present invention, thinking immediately and various equivalence variation.For example, window can change demonstration arranged side by side into, and non-overlapped demonstration, or the like.So all according to a notion of the present invention and spirit impartial for it a variation or modification, all should be included in the claim scope of the present invention.
