Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention is used in an electronic timepiece having a function of storing data.

[Prior art]

2. Description of the Related Art Electronic watches with a so-called data bank function that store data such as names and telephone numbers in a memory within the electronic watch have been commercialized. If the data stored in a conventional electronic watch with this function is, for example, a person's name and phone number, the name-(telephone) number should be associated with the address as shown in Figure 7a. is memorized. Moreover, the data is arranged, for example, in alphabetical order of the first letter of the name, as shown in FIG. When searching for a telephone number, the search is performed sequentially from top to bottom (in alphabetical order) as shown by the arrow in FIG.

[Problem that the invention attempts to solve]

In the conventional electronic watch with a data bank as described above, when searching for data, the data is sequentially searched in alphabetical order, so it takes time to search. In particular, a longer search time is required if the first letter of the name is located in the upper half of the alphabetic array.

An object of the present invention is to provide an electronic timepiece that makes it possible to search for data in a short time in the above-mentioned cases.

[Means to solve the problem]

FIG. 1 is a functional block diagram of the present invention. In the figure, 1 is a key input unit having a selection switch and a mode changeover switch, 2 is a data storage means for storing a plurality of data including names and telephone numbers, and 3 is a plurality of data stored in the data storage means. A display control unit 4 reads out a plurality of data from the data storage unit 2 and displays them on the display unit 4a according to the search count data of the search count storage unit. Reference numeral 5 denotes a search count updating unit for updating the search count data of the data displayed by the display control unit 4.

[Effect]

When the search mode is specified by the mode changeover switch of the key input section 1, each time the selection switch is operated, the display control means 4 controls the data storage means 2.
A plurality of pieces of data are read out from the search count storage means 3 in descending order of search count data and displayed on the display section 4a, and when the mode changeover switch is operated again and the search mode is canceled, the display time of the selected data is determined. This is to update the search count data of the data that is displayed only when it is longer than a certain time.

[Example of idea]

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 2 is a block diagram showing the circuit of the electronic timepiece of this embodiment. In the figure, to explain this circuit configuration, the reference clock signal of, for example, 32.768Hz, which is constantly output from the oscillation circuit 7, is transmitted to the frequency divider circuit 8.
The frequency is divided to, for example, 256 Hz, and is applied to the clock timing signal generation circuit 9. The clock timing signal generation circuit 9 outputs a signal a every 1/16 (16 Hz) and provides it to the address section 10. As a result, the address section 10 specifies a predetermined address in the ROM (read only memory) 11 and starts the timekeeping processing program.

Further, the high frequency clock output from the oscillation circuit 7 is also given to the timing generator 12,
The timing generator 12 operates in accordance with this and outputs various timing pulses to operate each circuit.

On the other hand, the input unit 13 is provided with numeric keys, function keys, etc. (not shown) for inputting data such as a person's name and telephone number. When these keys are operated, a key operation signal b is output from the input section 13 and is applied to the address section 10 and timing generator 12 described above. By inputting this key operation signal b, the address designated for key processing is selected in the address field 10, and thereby the ROM1
A key processing program corresponding to the first operation key is started.

ROM 11 stores microprograms that control all operations of this electronic watch, and uses microinstructions.
Outputs ADDR, DO, NA, and OP in parallel. Among these, the microinstruction ADDR is output to the RAM (random access memory) 14 via the address bus (ADDRESS-BUS), and
Specify 14 addresses. Also, micro instructions

BUS) to the multiplexer 15. The contents of the clock timing signal generation circuit 9, the key code from the input section 13, and the output data from the RAM 14 are also input to the multiplexer 15, and the multiplexer 15 switches and outputs the operand and operand at various processing timings, and performs the operation. section 16 and temporary register 17. In this case, the data held in the temporary register 17 is provided to the arithmetic unit 16 in synchronization with the output data of the multiplexer 15. Further, the microinstruction NA is outputted to the address control unit 10 as next address data for reading various microinstructions necessary for the next process. Furthermore, the microinstruction OP is output to the operation decoder 18. The operation decoder 18 decodes the microinstruction OP,
For example, a signal C for canceling the HALT state, which will be described later, is output to the timing generator 12, which outputs a control signal according to the microinstruction OP to each circuit.

In addition to key input processing, time measurement processing, and display processing, the calculation unit 16 counts the number of times data stored in the RAM 14 is searched, and the resulting data is
Output to RAM14. As shown in FIG. 3, the RAM 14 also has a memory area 14a for names and a memory area 1 for telephone numbers corresponding to each address 1 to n.
4b and a count area 14c for counting the number of searches. Although not shown, it also has a timer area. On the other hand, data writing to the RAM 14 and data reading from the RAM 14 are performed by the timing generator 12 at each processing timing. The name and telephone number data read from the RAM 14 are output to the display section 19.

In addition to the above-mentioned name and telephone number data, the display section 19 also displays the time, date, etc. according to the clock data generated by the clock timing signal generation circuit 9.

The circuit operation of the electronic timepiece configured as described above will be explained below using the flowchart shown in FIG.

First, a key/timekeeping judgment is made (step ST1).
Every time the 16Hz signal a is output from the clock timing signal generation circuit 9, the address section 10
11 to run the timing program (step
ST2). By executing this program, the clock data of the clock timing signal generation circuit 9 is output to the display section 19, and the time, date, etc. are displayed (step
ST3).

On the other hand, when writing or reading data such as a telephone number or name, this is done by operating a predetermined mode key on the input section 13. When this key operation is performed, the address section 1 is
0 causes the ROM 11 to execute a write or read processing program. At this time, the above-mentioned key/timekeeping judgment (step ST1) judges the key input, and judges whether the key operation is one of the function keys (mode keys) or the write key (step ST4). ). Based on this judgment, if data is to be written, the ROM 11 executes the write processing program, and the other mode keys on the input section 13 are operated in sequence to enter the required name and telephone number data.
Write to RAM14 (steps ST5, ST6). For example, the data written to the RAM 14 at this time is "NAKADA" in the name area 14a of address 1, and "24-1814" in the telephone number area 14b, as shown in FIG. . Further, data "KASIO" and "55-7211" are sequentially written to address 2, and data "SAITO" and "25-8940" are sequentially written to address 3.

On the other hand, if the above-mentioned key operation is a read key operation for reading data in the RAM 14 written as described above, the ROM 11 is caused to execute a read processing program. This data read processing includes frequency search processing (steps ST7 and ST8) and alpha-betting search processing (steps ST9 and ST10).
It can be divided into Both processes are selected in advance by operating a switch (not shown) of the input section 13.

First, this frequency search process will be explained in detail using the flowchart of FIG.

First, the calculation unit 16 reads out the name and search frequency data in the RAM 14, and compares the search frequency for each name (step ST7-1). A method such as bubble sort is used to compare the search frequencies. As a result of this comparison, the names are ranked in descending order of the number of times they have been read and written into an area (not shown) in the RAM 14 as, for example, P ₁ , P ₂ . . . P ₁₀ (step ST7-2). For example, in the example shown in Figure 3, the address corresponding to the name "NAKADA" is written in the _P1 area, the address corresponding to the name "KASIO" is written in the _P2 area, and the address corresponding to the name "KASIO" is written in the _P3 area. The address corresponding to the name "SAITO" is written.

Next, set the initial value of the counter in RAM14 to “0”.
"(K=0) and starts the timer (steps ST7-3, ST7-4).Then, the value K of the counter is +1 and the data of the corresponding name is displayed (steps ST7-5, ST7-4). 6).

For example, according to the above example, the name data corresponding to the name address written in area _P1 is "NAKADA". Therefore, at this time, the name "NAKADA" and the telephone number "24-1814" from the telephone number area 14b corresponding to address 1 of "NAKADA" in the RAM 14 are output to the display section 19 and displayed.

Next, it is determined whether the selection key has been operated (step
ST7-7), if the operation is performed before the timer times out (step ST7-7 is Y), 0, K
=10 (step ST7-8), and then sets the timer again. Then, in the same way as described above, the counter value K is incremented by 1 and the data of the corresponding name is displayed (steps ST7-5, ST7-6).

For example, according to the above example, the name data written in area _P2 is "SAITO".
Therefore, at this time, the telephone number "25-8940" is output from the telephone number area 14b corresponding to address 2 of "SAITO" in the RAM 14 of the name "SAITO" to the display section 19 and displayed.

Similarly, steps ST7-4 → ST7-5 →...
...Repeat ST7-8 → ST7-4, display section 1
9 to display name and phone number data in order of search frequency. FIG. 6 shows an example in which names and telephone numbers are displayed in order of search frequency as described above.

This display progresses one after another, and when the counter value K reaches 10 (Y in steps ST7-8), set K to "0" again.
(step ST7-9), and then similarly
The name and phone number are displayed sequentially in response to the address data starting from the _P1 area.

On the other hand, when this processing mode key is operated,
Stop the timer (steps ST7-10, ST7-
11), it is determined whether the timer is longer than 1 minute (ST7-12). As a result of this determination, if it is longer than one minute, the data Ni in the number of searches area 14c corresponding to the displayed name is incremented by 1, and the number of times the name has been searched is increased by 1 (step ST7-13). That is, if data with a certain name is displayed for a specified time or more, it is recognized as a search. Further, if the timer time is 1 minute or less, it is not determined that a search is being performed.

As described above, in the frequency search process, names and phone numbers that have been searched the most are displayed in order.

On the other hand, alpha search processing (step
ST9) is to sequentially search in alphabetical order of names as in the past, and in this embodiment, input section 1
It can be arbitrarily selected by operating a switch (not shown) at 3.

[Effect of idea]

As explained in detail above, according to the present invention, data is displayed in order of frequency of use, so not only can data be searched quickly, but when the search mode is canceled, the data display time is Since the number of searches for that data is updated only when a certain amount of time has elapsed, the number of searches will be updated when the search data is actually used. Since it is not updated when checking, it is possible to accurately count the number of searches. Furthermore, since the number of searches is updated in conjunction with the mode changeover switch, the switch operation is simple and convenient.
