Abstract

PURPOSE:To shorten a processing time by providing information regarding timbre separately from musical sound information and text information and storing them on individual storage devices, and displaying the progress of music and its text synchronously by one CPU while timbre used for the music is loaded in a timbre memory by the other CPU. CONSTITUTION:When desired music is selected, the CPU 1 loads a file of the corresponding music and text, but the file number of the timbre which is used is entered into a 1st block, so this is transferred preferentially to a common memory 5. then the CPU 2 reads the specified timbre out of a disk 2 according to the information and loads it on a timbre memory 5. Thus, the loading of all timbre is completed and then the CPU 2 outputs an end trigger (c) to the CPU 1 to indicate the completion of the processing. Further, the CPU 1 loads the music and text information during this period and then the presence of the end trigger (c) is confirmed to start performance processing for music repro duction and a display of the text. Consequently, a longer time between the processing of the CPU 1 and the processing of the CPU 2 is a setup time.

Description

[Detailed Description of the Invention] C. Industrial Application Field] The present invention relates to high-speed processing for performing data processing at high speed when playing and displaying karaoke information such as songs and lyrics that have been digitalized as computer information. Regarding the mechanism.

[Conventional technology and its problems]

The present invention is based on a completely new technique in which all karaoke information such as songs and lyrics are binary digital information and this is reproduced or displayed. The applicant has disclosed a series of inventions related to these techniques (for example, Japanese Patent Application No. 308503/1983, Japanese Patent Application No. 3086/1999, and Japanese Patent Application No. 11298/1999).

In this case, the data for one song is a considerable amount of information when you combine the information about the song and the information about the lyrics, but on a karaoke terminal, most of the time required from song selection to playback (cent up time) is from the storage medium. This is the file load time. Therefore, if the time required for these loads can be shortened, the terminal can be started up quickly. However, since the present invention attempts to handle information regarding timbre as data, the amount of information per song increases considerably. Moreover, since the tones used in the karaoke terminal differ for each song, the data regarding the songs, lyrics, and tones has a total size of more than 100 KB. Furthermore, since the tones to be used are written in the music information, it is not possible to independently read and process just the tones in advance.

By the way, currently, devices that generally require a long setup time are trying to shorten the time by improving the read speed from the storage device, but it is difficult to store the necessary data in 11@
It is not possible to avoid reading the data at the same time.

The purpose of the present invention is to shorten the set-up time mentioned above. Two storage devices are used, one of which is dedicated and the other is used to process information related to timbre. We provide a mechanism that can do two things to shorten the time.

[Means for Solving the Problems 2. The present invention achieves the above-mentioned purpose. 7. First, the music and lyrics are digitally encoded.Zl'w karaoke information is processed. δ
One of the storage devices stores information about songs δ and lyrics for a large number of songs, and the other storage device stores a lot of timbre information, and each data is controlled by a separate CPU.
These two CPUs share one memory and form one CPU.
U is used only for writing, and the other CPUs are used only for reading, and according to the data read from the shared memory by the other CPU, a necessary tone is read from the other storage device and loaded into the tone memory L.

: Function: One storage device has the function of exclusively storing music and lyrics information, and the other storage device has the function of storing a large number of timbre information, that is, a large number of sampled waveforms of various musical instruments. . Each of these devices is controlled by a separate CPU, but the CPU that controls one storage device
] performs a write-only operation on the shared memory 22, and the CPU 2, which controls the other device described above, performs a read-only operation on the shared memory. Then read from the shared memo IJ', -;' according to the code data CP! j
2 reads the necessary tone information from the other storage device,
It performs the function of loading into tone memory.

[Embodiment] Hereinafter, one embodiment of the present invention will be described in detail with reference to the attached drawings. Fig. 1 is a block diagram of the mechanism of the present invention, and 1 indicates information such as the strength and length of the sound in the karaoke information. 2 is a magnetic or optical disk that stores music information and lyrics information, 2 is a disk that stores timbre information regarding the timbre of reproduced sound, and 3.4 is a disk control device that controls each of the disks 1.2. and CPtJl and CP, respectively.
It is connected to tJ2, and processing is performed by this. Reference numeral 5 denotes a shared memory between the CPtJ l and the CPU2, which functions as a write-only memory for the CPUI and a read-only memory for the CPU2. 6 is the peripheral circuit such as I10 port and sequencer, 7 is the memory required for this peripheral circuit 6S, 8 is the tone memory for storing the tone necessary for the selected song, 9 is the CPU 2 and the tone memory 8. 1 for connecting
/'○ port and other peripheral circuits; 10 is a sound source that performs analog processing on binary information and outputs a signal to an audio device;

a is a control signal for the shared memory 5, b is a control signal from the CPU 1 to CPt
Read start trigger for J2, C is from CPU2 to C
The reading end trigger for the PUI, d, is a performance progress signal from the peripheral circuit 6 including the sequencer. In addition, C.P.
U, memory, peripheral circuits, etc. are each connected by a lotus.

Next, FIG. 2 is a block diagram showing the connection between the shared memory 5 and the CPU 1.2, in which signals are output from the address decoders 11.12 of each CPtJ by the read start trigger b and the FC extraction end trigger C. Chimpselec)
(C3) is activated to select connection of the shared memory 5. Also, the output of control signal a is CPUI or CPt,'
The CPU 2 and the shared memory 5 are connected to each other in a 3-state H.7 circuit in an inverted relationship to prevent the two CPUs from accessing the CPU at the same time.

The operation of the mechanism configured in this way will be explained.

First of all, the song information and lyrics information of the karaoke information is stored on disk 1, and the tone information is stored on disk 2, but the first program of the song information/lyrics information file contains the file number of the tone used in that song. is listed. Next, when you select the desired song, the CPU loads the corresponding song/lyrics file, but at this time, the first block contains the file number of the tone to be used.
This is preferentially transferred to the shared memory 5. and CPU
2 reads out the specified tone color from the disk 2 according to this information and loads it into the tone color memory 8. When all tones have been loaded in this way, the CPU 2 outputs a termination trigger C to the CPU 1, notifying the CPU 1 that the processing has been completed. CPL again! In 1, the music/lyrics information is loaded during this time, but when this is finished, the existence of the end trigger C is confirmed.
Then, the process moves to the performance process of playing the music and displaying the lyrics. Here, if the end trigger C has not been output yet, the process waits until this output is received. In this way, the set-up time is the longer time of either the CPUI processing or the CPU 2 processing.

FIG. 3 mainly shows the processing of the CPU 1 in a flowchart, and FIG. 4 mainly shows the processing of the CPU 2.

〔Effect of the invention〕

In the present invention, information regarding timbre is provided separately from music information and lyrics information, and these are stored in separate storage devices,
One CPU performs the progression of the song and synchronized display of the lyrics, while the other CPU loads the tones used for that song into the tone memory, so data processing can be divided between the two CPUs. , we were able to significantly shorten the required processing time.

Furthermore, since only information related to timbres is stored in one storage device, the access time for retrieving the necessary timbres is shortened, and there is no longer a need to wait for a long time from song selection to the start of playback.
