BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a multi-polyphony generating device, comprising a sequential block unit transmission of a MIDI (Musical Instrument Digital Interface) signal, which is an international standard that defines a communication method of an electronic music period, The present invention relates to a semiconductor non-memory apparatus for generating a simultaneous sound using automatic section repetition and memory data crossfade modulation (cross modulation of a certain section signal), which can adjust the speed of sound generation without changing the frequency.

Recently, with the development of semiconductor integrated technology, a semiconductor has been developed that can easily implement a musical instrument sound or modulate the implemented sound by exchanging a simple signal. In order to implement a musical instrument sound in a mobile phone, electronic musical instrument, or entertainment device, a processor capable of implementing a semiconductor or MIDI function with a MIDI function in software is required. In other words, in order to play the sound by reading the sound parameters in the memory by receiving the MIDI signal in the existing serial or parallel, the processing function for interpreting the MIDI signal should be separately external and separate the voice when processing simple music by time. I couldn't handle it. In other words, conventional MIDI non-memory semiconductors could only process simple MIDI itself, but could not mix (mix) with audio signals not defined in the MIDI.

On the other hand, devices equipped with MIDI functions, such as a central processing unit (CPU), DSP (DSP), etc. separately from the non-memory semiconductor for MIDI, high manufacturing cost is required. Therefore, studies are being actively conducted to simultaneously implement audio signals of MIDI and non-MIDI using general MIDI semiconductors.

As illustrated in FIG. 1, when an externally connected device wants to make a specific sound, the user request S100 that recognizes a user request receives the desired information required for the MIDI. The selection unit (S102) that determines whether or not the information can be satisfied using the MIDI during the user's request determines whether the MIDI information is to be used in the internal memory or the information in the external device. To organize. In this process, if the sound in the internal sound processing unit (S106) can realize a sufficient sound, if the specific information is not requested from the outside, and if the sound cannot be implemented as a sound not internally, a selection unit made to receive external sound information ( S102 sends a signal to the external device to send the sound information sequentially to the memory. At this time, the user request (S100) part may request a specific function from the inside to the outside, or the desired information from the external device may be mixed and sent to the inside.

In the external sound storage and processing unit (S104), if only a simple wave sound is lowered, the general wave (S116) circuit is used, and if the automatic section repeat external sound is used, the automatic section repeat (S114) external sound is used. The automatic section repeat external sound is mixed with the MIDI, and the sound passing through the simple external sound circuit is selectively mixed with the MIDI sound through the speed converter S118 and the normal speed part.

However, when the sound in the external memory and the internal memory is reproduced with the desired sound through the desired normal procedure, the user inputs it to the sound modulator (S110) that can modulate a specific sound when the user wants to play various sound quality. Can be. In this case, since the sound must finally flow to the outside, the output circuit S112 is configured in accordance with the external interface. In this process, the sound can be reproduced using MIDI, so information for sound reproduction that an external device should have can be very monotonous, and under special conditions, MIDI can be reproduced using sound from an external memory. Can overcome the monotony of information. The reduction of the amount of information of the MIDI itself is an advantage that an external memory cannot have. Therefore, a maximum effect can be obtained when sound is reproduced by appropriately harmonizing an internal and external memory. In addition, the various parameters reproduced by MIDI can be implemented to enable the modulation of sound beyond the reproduction of simple sounds.

SUMMARY OF THE INVENTION An object of the present invention is to solve the above problems, by using the address phase generator, tone data memory, automatic interval repeat memory, voice variable speed special memory, sound modulation data memory at the same time as MIDI And the circuit that simultaneously and directly process the instrument sound and external wave specified in MIDI so that the automatic section repeat function can be performed. By combining the voice function with the MIDI function, the MIDI function and the external wave are improved. It is to provide a multi-sound simultaneous generation device capable of simultaneous implementation of the MIDI wave / automatic section repetition wave / speed-controlled wave / original sound wave using a cross signal and an address phase modulation method that can be mixed at the same time.

One aspect of the present invention for solving the above technical problem relates to a semiconductor non-memory device.

It's about how to do that.

In order to fully understand the present invention, the operational advantages of the present invention, and the objects achieved by the practice of the present invention, reference should be made to the accompanying drawings which illustrate preferred embodiments of the present invention and the contents described in the accompanying drawings.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. For each figure, like reference numerals denote like elements.

Figure 2a is an overall configuration diagram of the sound generation method that can be implemented simultaneously the MIDI wave / automatic section repeat wave / speed controlled wave / original sound wave using the cross signal and the address phase modulation scheme of the present invention.

The sound generating system includes a MIDI buffer 310 and a wave buffer 312 that can receive MIDI or wave data from the outside.

The external command interpretation circuit 314 is used when the data written by the external host starts and ends, whether the buffer memory must be divided into the MIDI buffer and the wave buffer, and the buffer is divided into one, that is, only the MIDI data is received. Determining whether only data can be received, that is, using either MIDI or wave, and whether received data is not available for a certain period of time before going to sleep mode, what conditions should be given to wake up from sleep mode, and automatic section if wave data It acts as an intermediary to determine if there is a repeat function, if it is a normal wave, whether or not speed conversion is necessary.

The buffer address generation circuit 316 determines the data output rate determined by the external command interpretation circuit 314 or which of the internal channels should be allocated when making a sound in the internal digital signal processor (DSP). And determine the address of the external buffer according to the required output speed or the desired instrument sound.

The MIDI command interpretation circuit 318 reads the external buffer if the command indicates the start by reading the start and end of the command through the external command interpretation circuit 314 (sequencer). At this time, the start and end of the music is judged according to the contents of the buffer.In the case of start, the appropriate channel is allocated to the internal DSP function part to indicate the beginning of the sound, and when the sound needs to be intermodulated while the sound is generated, MIDI is indicated. The command delivers the information to the modulation circuit of the channel.

The MIDI command delivery circuit 320 provides the necessary information in a predetermined order according to the interpreted command when the MIDI command interpretation circuit 314 interprets the MIDI command and delivers the appropriate data to the address phase modulation circuit 322, which is one of the sound generators. It is a circuit that writes information such as size, frequency, assigned channel number, and sound length. At this time, when one command delivery has not yet been performed, a control circuit that can control the next command functions. The control circuit is designed to wait for one sampling cycle as a whole and then execute the next command when a condition occurs that requires control that has not yet been performed.

The address phase modulation circuit 322 is a circuit for creating an address of a memory for managing the tone data memory 402, the tone size adjustment data memory 423, and the tone modulation data memory 406 of FIG. The circuit 326 modulates the sound by the data read from the decoder 410, the address phase generator 2 420, and the sound modulation data memory 406.

The wave speed converting circuit 336 transfers the wave signal converted at the desired speed by FIG. 4 to the final data modulating circuit 326 to perform final mixed modulation with the data entered through various data memories.

The memory address / data access circuit 324 reads the memory independent of the address determined by the address phase modulation circuit 322 which determines whether to use the internal data memory 328 or the automatic section repeating memory 334. The time division is appropriately performed so that the data buffer 328 storing the internal data and the MIDI buffer 310 and the wave buffer 312 storing the data from the outside are read so that they do not collide when trying to write. The data memory 328 includes a tone data memory 402, a tone control data memory 423, a tone modulation data memory 406, and the like. If two or more of the three types of data (voice, scale, sound modulation) are to be read simultaneously in the same cycle, give priority to the tone data memory 402 and the priority of the next two (sound size, sound modulation). .
The automatic section repeating control circuit 337 is a circuit driven when the automatic section repeating memory 334 is used. First, when a single sound is reproduced by the automatic section repeating control circuit 337, a certain section of the memory is repeatedly used. Or, second, use only once, not repeat once, third, use a certain section only once, and the subsequent section serves to create a repetitive address that can be used repeatedly.

The multiplex sound control circuit 338 is capable of simultaneously sounding a MIDI sound using a normal internal data memory 328, a MIDI sound using an automatic section repetition memory 334, and a wave in which a speed change is generated. This is a simultaneous generation circuit that mixes (Mixing).
The multiplexing sound control circuit 338 includes a memory for controlling each input sound for each channel and each of the MIDI sound using the basic MIDI sound and the automatic section repeating memory 334, and the wave sound of which the speed is changed. 406) stores information such as sound level, sample rate, desired frequency characteristics, and sound length, and makes final output using previous sample value and previous output value of each channel.

The D / AC input circuit 330 and the final output circuit 332 are digital analog converters because data must be transmitted to a digital analog converter that converts digital to analog in order for the signal finally output from this circuit to be converted into sound. It converts the signal type that is needed.

3 is a block diagram showing a device for detecting MIDI information (writing data to a RAM memory). Since the system is not always in operation and most of the time is in the ready state, when the external device receives a signal from the power saving mode release part that it needs to be operated from the outside, it checks whether it is ready internally. Wait until it is ready and send the start command if it is ready.

When the operation is started, the RAM memory data writing function for writing data to the MIDI buffer 310 and the wave buffer 312 which are RAM memories is started. Once the data comes into the RAM memory from the outside and the MIDI and wave are mixed, if it is mixed, the MIDI / Wave decision circuit is used to write the MIDI buffer to the MIDI buffer. In this case, it is determined whether the automatic section repeat wave or the normal wave, and if the automatic section repeat, write to the automatic section repeat wave buffer (S131) and set the automatic section repeat mode. If it is the normal wave mode, it is determined whether the speed conversion mode (S132), and if the speed conversion mode, it is set to the speed conversion mode. If the signal is not mixed with the MIDI and wave to write directly to the MIDI buffer (S126). In both cases, whether MIDI and Wave are mixed or separated, a stop command is sent to the internal sound generator when it is determined that the end of the file is in the end-of-file detection circuit that always determines where the end of a block of data is. If it is not the end, it is determined whether the end of the external MIDI and wave buffers 310 and 312 has come, and if it is the end, new data is requested from the outside again, and if not, the data is written to the external buffers 310 and 312 continuously.

Figure 4 is a configuration diagram for making a cross-signal modulation sound as a previous step to give a speed conversion to the incoming wave. If the input original wave is referred to as period A, period B, and period C (S340), it is necessary to first determine whether to slow down or speed up the wave speed. Multiply 1 / N, 2 / N, ... N / N from the first sample data to form a cross-modulated period A (S342). Conversely, in order to cross-modulate period B, the wave of original period B is multiplied by N / N, (N-1) / N, ... 1 / N from the first sample data, and cross-modulated period B (S344) is obtained. Make. The cross-modulated period A (S342) and the cross-modulated period B (S344) are added for each sample (ADDITION) (S346) to generate a cross-modulated period A '(S348) signal. The final result of S350, which slows the wave speed, is the period A '(S348) signal.

 The newly generated period A 'signal is used as an intermediate medium for slowing the wave speed, and the data to be finally output sends the period A, period A', period B, and period C (S352) to the actual output. However, if you need a structure that wants to make the wave speed faster, for the cross modulation of period A, multiply N / N, (N-1) / N, ... 1 / N by the original wave from the first wave to the original wave. Cross-modulated period A (S354) is made. Conversely, in order to cross-modulate period B, the wave of original period B is multiplied by 1 / N, 2 / N, ... N / N from the first sample data to form cross-modulated period B (S356). The cross-modulated period A (S354) and the cross-modulated period B (S356) are added for each sample (ADDITION) (s358) to generate a cross-modulated period B '(S360) signal. The final result of S362 is the result of S360. The newly generated period A 'is used as an intermediate medium for slowing the wave speed, and the data to be finally output is the period B' and the period C (S364) to the actual output.

5 is a cross signal modulation flowchart for the speed conversion circuit of the present invention. A predetermined amount of data corresponding to a predetermined speed is read from the automatic section repeating memory 334 of FIG. 2 in the same form as S340 of FIG. 4 (S136). The required period is found in the read wave (S138). The found cycle can be slowed down, speeded up, or discarded, or output to the outside. First, if a command to speed up or slow down is determined by the fast / slow determination circuit (S140), the data is discarded as much as the period found in the read data as shown in S364 of FIG. 4 (S144). After that, the data created in S364 of FIG. 4 is output to the outside. If the instruction to slow down the first found period is output to the outside as it is (S146), and the period A '(S348) of Figure 4 outputs in the form of S352. Then, the wave output to be output is returned to its original position before the period search.

6 is a block diagram showing a sound generating unit that is a portion for generating a sound corresponding to the conversion signal from the MIDI input terminal. The address phase modulation circuit 322 of FIG. 2 includes an address phase generator 1400 for managing the tone data memory 402 and an address phase generator 2 420 for managing the tone size control data memory 423. The address phase generator 3 (404) that manages the modulation data memory 406, the tone data memory 402 that stores a specific parameter of the instrument in order to reproduce the MIDI, and the user wants to change the volume of the sound over time. Sound size control data memory 423, which stores sound size information for satisfying this, sound modulation data memory used to change the desired tone to a different color while changing the size of the sound when playing the stored tone ( 406, the information from the tone data memory 402, which stores the tone parameters, may sometimes be compressed information or may be used as it is. At this time, the compressed data should be restored to its original state. The decoder 410, which is a circuit for restoring the compressed data, includes a compression table memory 1 411, a compression table memory 2 412, an adder 413, and an output delay unit 414. It is. The compressed table memory 1 411 stores information on the difference between the previous sample value and the current sample value in the original sample, and the compressed table memory 2 412 contains information mapped 1: 1 with the original sample information. . The output delayer 414 delays the recovered information by one or two samples and outputs the information from the compressed table memory 1 411 to the output 415 using the adder 413. The reconstructed information is selected and exported using only the selector 416 to match the user's intention. The selector 416 may also select to transmit the information output from the tone data memory 402 to the outside, separately from the compression table memory 1 411 and the compression table memory 2 412. The address phase generator 2 420 receives the reference address 421 from the outside and reads the information contained in the tone size control data memory 423 to multiply the tone size calculated by the tone size operator 424. Send to At this time, the address pattern generator 425 calculates the next necessary address by using the information in the tone control data memory 423. The calculated address enters the adder 422 together with the reference address 421 and adds, and then the output of the adder becomes the address of the final tone control data memory. The multiplier 1 408 receives an output of the decoder 410 and an output of the address phase generator 2 420, multiplies the multiplier, and sends the multiplier 1 to the input of the modulator 430. The modulator receives the output of the modulator data 406 and the output of the multiplier 1 408 as inputs, performs calculations, and sends it to the final output 432. The sound modulation data memory 406 determines the address by the output of the address phase generator 3 (404) and outputs data corresponding to the address to the outside.

7 is a flowchart for explaining the structure of the address phase generator 1440. If the data coming from the MIDI is information for turning on the sound, the address of the tone color corresponding to the reference tone is determined, and the address of the tone data memory 402 is changed by the external control key variables 1, 2 and the like. At this time, the variable coming from the external control key variables 1, 2, 3 (442, 443, 444) may be negative or positive. External control key variables can sometimes be converted to sinusoidal forms and convert the sign (positive and negative) into 1 bit of information. When it is difficult to realize the desired sound in the sine wave form, it can be implemented using only the absolute value of the sine wave, or sawtooth wave, giant wave, or square wave. At this time, the external control key variables are stored in wave shaper table memory 1, 2, 3 ... and used. The control key variable is multiplied by the reference keyon address 441 and the multipliers 445, 446, ..., and the output of the multiplier stores the final tone data memory 402 and externally transmitted wave data through the adder 447. This is the address of the external wave memory S404. At this time, the selection of the external wave memory and the tone data memory is selected by adjusting the memory selector S406 by the central processing unit. The data of the external wave memory S404 is wave data, and modulated and stored by the speed adjusting modulator S408.

Although the present invention has been described with reference to one embodiment shown in the drawings, this is merely exemplary, and those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom. Therefore, the true technical protection scope of the present invention will be defined by the technical spirit of the appended claims.

According to the non-memory semiconductor device which generates the MIDI, the automatic section repeating wave, and the downloading wave sound of the present invention, in the normal MIDI state, the sound generating method uses the sound-related information in the internal memory to control the external MIDI signal. It generates the desired sound by receiving a command from the MIDI and proceeds to generate the sound while receiving the sound not in the internal memory from the outside and mixing it with the MIDI. It can be used to produce the same wave effect as musical instruments. By optimally using the stored voice-related parameters to generate abundant sounds with a minimum of memory, the sound generation circuit can be reduced to a minimum while using the memory optimally. Any sound can be implemented according to the command from the outside. At this time, the external wave can have the same effect as the MIDI used in the internal memory by using the automatic repeating circuit. This effect can have the same effect on the voice, and can also control the frequency modulation and the speed of speech generation.
