Problems solved by technology

[0003] However, when the user operates the computer, if the aforementioned abdication key, the last item clear key, the clear key, the memory clear key or the memory call clear key are pressed by mistake and the useful data disappears, because the existing computer can only To clear or modify the last input value, the value displayed before clearing cannot be restored after clearing. Therefore, the user must restart the entire calculation process, which leads to unnecessary waste of time and inconvenience in computer use. Therefore, It is necessary to improve the aforementioned existing computers

Embodiment Construction

[0011] For a preferred embodiment of the computer of the present invention that can restore the value that has been cleared, please refer to figure 1 The computer architecture diagram shown is mainly composed of components such as an input unit 11, an output unit 12, an output / input buffer device 13, an arithmetic processor 14, a memory 15, a stack register 16, and a flag storage unit 17. The components 13-17 can be integrated into a processor and installed on a computer to provide logic operation and control functions.

[0012] The aforementioned arithmetic processor 14 provides processing functions of mathematical logic operations; the memory 15 provides program codes and memory space required for computer operations, for example, for storing calculated result values.

[0013] The aforementioned input unit 11 is, for example, a key set for the user to operate the computer, which includes numeric keys, arithmetic keys, a cancel key that can be used to cancel the data displaye...

Abstract

A computer able to restore the deleted data features that its input unit has a restore key for restoring the deleted data. When a delete key is pressed to delete the displayed or stored data, the data is stored in a stack latch and a flag unit is used to point the data. When a data is restored, it can be read out from the stack latch according to address pointed by its flag.

Description

technical field [0001] The present invention relates to a computer, and more particularly to a computer capable of recovering cleared values. Background technique [0002] Because computers have extremely convenient and fast calculation functions, they have been widely used in human life, such as shopping, accounting, mathematics or engineering applications, etc., in order to provide simple addition, subtraction, multiplication and division calculations or even complex calculations. The calculation of the scientific equation, and in the process of using, the user usually inputs some data items for calculation and processing. If the user finds an input error, the general computer provides a back key (BACK) to clear the input one by one. The key value of the data item, or use the last item clear key (CE) to delete the current data item, or directly use the clear key (C) to delete this data item, and before the final result, there will be many intermediate As a result, it must...
