Abstract

PURPOSE:To surely understand the operating state by an easily visible display by deciding an address signal inputted in a real time, based on a set display condition, calculating a decision output and displaying a state of an address signal varied momentarily, as a two-dimensional color image. CONSTITUTION:An address signal from a computer 1 passing through an address bus 2 is inputted to a comparing and deciding circuit 4 in a real time through an adaptor 3 of a computer operating state display device 10. Subsequently, its comparison and decision to a set display condition of a display condition setting part 5 are executed, a result of decision is calculated by a display arithmetic circuit 6 and the correspondence of an address signal and a memory address is determined, and an operating state of a computer such as an access frequency, etc., of the address signal is displayed as a two-dimensional color image pattern on a display 8 through an image memory 7. By this easily visible display, the computer operating stage is understood surely, and an abnormal run of a program, an overhead of an operating system, a use rate of a CRT, etc., can be decided visually.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device for displaying the operating status of a computer. [Prior Art] Conventionally, computer operating status display devices have been used to indicate that the computer is in operation by blinking a lamp or LED;
There are devices that display the signal status of an address bus or data path as is on a lamp or LED to display macroscopically which address or data is being accessed by the computer. [Problems to be solved by the invention] The above-mentioned conventional display devices have the following problems: (1) Since the operating status is displayed using a single lamp or LED, the amount of displayed information is small, making it impossible to accurately grasp the operating status. ．． (2> Since the signal status of the address bus or data path is displayed directly on a lamp or LED in real time, it is difficult to see and confirm the contents.

There are drawbacks such as. [Means for Solving the Problems] The computer operating status display device of the present invention includes a signal input means for capturing address signals on an address bus of a computer to be monitored in real time, and a condition setting means for setting display conditions. , a determining means for comparing and determining the address signal obtained as an output of the signal input means and the display condition; a calculating means for calculating the output of the determining means and writing it into a two-dimensional screen memory; The computer has a display means for displaying contents, and is configured to calculate the operating state of the computer from an address signal that changes every moment and display it as a two-dimensional image. [Example] Next, the present invention will be explained with reference to the drawings. FIG. 1 shows one implementation of the present invention, in which the screen position of the CRT display corresponding to the memory address is changed in display color according to the access frequency (parts that are not accessed are black). This is a block diagram of a computer operating status display device that allows access status (program running pattern) to be grasped in a two-dimensional color image. Also, Figure 2 shows computer memory addresses (address groups) and display positions on a CRT display screen. The computer operating state display device 10 inputs the address signal on the address bus 2 of the computer 1 to be monitored into the address comparison/judgment circuit 4 via the adapter 3 in real time. The determination circuit 4 determines whether the memory access address indicated by the fetched address signal is within the address range for each address group (a set of addresses belonging to a certain memory address range) established by the display condition setting section 5. If there is, the No (Gi) of that address group is notified to the display calculation circuit 6 at the next stage.
Based on the instructions from the display condition setting section 5, the arithmetic circuit 6
The number of address group numbers notified within time t is added for each group number to obtain the number of accesses Ni to the address group Gi. Next, a display color Ci corresponding to the number of accesses Ni is calculated by an instruction from the display condition setting unit 5, and this display color Ci is written in the display position Ai corresponding to the address group Gi in the screen memory 7. The calculation circuit 6 repeats the above calculation at time intervals of t. On the other hand, the contents of the screen memory 7 are displayed on the CRT display 8, and the program running pattern of the computer is
This can be understood as a change in the dimensional color image pattern.

〔Effect of the invention〕

As explained above, when the computer operating status display device of the present invention is used, the operating status of the computer can be understood as changes in a two-dimensional color image, so abnormal program execution, OS overhead, CRT usage rate, etc. can be visually detected. This has the effect of making it easier to understand and understand.
