Description of the Invention (1) The present invention relates to a processing device having a Reduced Instruction Set Computer (R I S C) unit and a coprocessor unit. : Generally, if you want to use R I S C to perform simple pure loop processing such as voice processing, the address generation of the memory or the determination of the loop must also be performed using A LU (Arithmetic and Logic Unit) of R I S C, so the above processing takes a lot of time. In order to eliminate such a problem, in the past, a processor device having a structure in which an R I S C part and a D and SP (Digital Signal Processor) part are considered is considered. Figure 7 shows the architecture of this conventional processor device. This conventional processor device includes an R I S C section 1. and a D S P section 60. The R I S C unit 1 includes a command register 3, a command reading unit 4, a register 5, a command decoding unit 6, a register 9, ALU1 0, a register 1 1, and a memory 12. The command decoding unit 6 includes a decoder 7 and a universal register 8. The DSP section 60 includes a temporary register 61, a command decoding section 62, a billion register 65i, 65, 653, and ALU67. The command decoder 6 2 includes a decoder 6 3 and an address generator 6 4 :, 6 42 and 6 4 3. Furthermore, the memory 6 5 i (i = 1, 2, 3,) is provided corresponding to the address generator 6 4 i. The commands stored in the command memory 3 of the RIS C section 1 are read by the command reading section 4. And if this read command is a command to be processed in R I s < ^ Section 1, it is sent to register 5 and a command to be processed in DS SP 60 is sent to register 61. The command sent to the register 5 is decoded by the decoder 7.

Description of the invention (2) The address part of the order is sent to the universal register 8. Then, the data stored in the address of the universal register 8 corresponding to the address in the above address portion is taken out and sent to the register 9. At the same time, the part other than the address part of the decoded command, for example, the operation code is sent from the decoder 7 to the ALU 10, and the data sent to the register 9 is used for arithmetic or logical operations. This calculation result is stored in the memory 12 through the register 1 1 and then sent to the universal register 8 or directly to the universal register 8 and stored in a certain address of the universal register 8 . On the other hand, the command sent to the register 61 of the DS unit 60 is decoded by the decoder 63. According to this decoded command, addresses are generated from two of the three address generators 6, 6, 42 and 6 43 respectively, and the corresponding memory outputs data. Using this data, A L U 6 7 performs an operation corresponding to the decoding command sent from the decoder 63 described above. The calculation result is stored in at least one of the memories 6 5 i, 6 5 2 and 6 5 3. In this way, in the traditional processor device, the DSP section 60 uses the address generator 6 4 \, 6 4 2, 6 4 3 to generate the address of the memory, so it is not necessary to use ALU to calculate, compared to the RISC without the DSP section. Can be used for high-speed processing. However, this conventional processor device has an ALU architecture because both the RISC section 1 and the DS section 60 have an ALU structure, so there is a problem of a large overall area. At the same time, program control is performed between RISC section 1 and DSP section 60, or the teaching and receiving operations of the data stored in the memory (please read the precautions on the back --- this page) Order ------- --Line 1 Printed by the Employees 'Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs This paper is printed to the Chinese National Standard (CNS) A4 (210 X 297 mm) -5-498275 Printed by the Employees' Cooperatives of the Intellectual Property Bureau of the Ministry of Economic Affairs A7 _ B7 _V.

The control signal 1 is used for the selection of correlation function calculation processing and overlap calculation processing. The control signal DATA LENGTH is used to set the length of the input data, and the control signal SHIFT LENGTH is used to set the shift length of the product sum. The control signal RSHIFT ENABLE is used to shift to the right, and the control signal ROUND ENABLE is used to set whether or not rounding is performed at the end of the calculation process. The control signal B U S Y is used to indicate whether the coprocessor section 20 A is being executed. Furthermore, the above five input control signals are sent from the universal register 8 and the set signals are sent from the decoder 7 to the control register 21. The address generators 2 3, ¾ 2 4, and 2 7 used in the processor device of this embodiment have the architecture shown in FIG. 3, respectively. That is, each address generator is provided with an address register 4 1, a selector 4 2, and an adder-subtractor 4 3, which can be based on the increment signal, the SET signal, and the addition and subtraction signals sent from the main controller 2 2.

Printed by the Consumer Cooperative of the Intellectual Property Bureau of the Ministry of Economic Affairs Next, the operation of the address generator will be explained. When the S E T signal is "1", the selector 4 2 selects the incremental signal and sends it to the adder-subtractor 43. The incremental signal is directly output by the adder-subtractor 43 and becomes the next address signal. On the other hand, when the E of the S E T signal is "0", the selector 4 2 selects the current address stored in the address register 41 1 and the increment signal, and sends it to the adder-subtractor 43. At this time, if the signal of the addition and subtraction signal is "0", the current address and the signal of the incremental signal on the force mouth.

Description of Invention (10) 4 3 is output as the next address signal. On the other hand, if the 値 of the addition and subtraction signal is "1", the difference between the current address and the incremental signal · number is calculated by the addition and subtraction device 4 3, and the addition result is obtained by the addition and subtraction device 4 3 as the next bit. Address signal output. The address register 41 updates the address when receiving this next address signal. The main controller 22 of the processor device used in this embodiment has a structure shown in FIG. That is, the main controller 22 includes a counter 51, a register 52, a comparator 53, and a state transition circuit 54. Next, the operation of the main controller 22 shown in FIG. 4 will be described.

At this time, the "SY" BUSY signal is output from the state transition circuit 54. Then, in order to set the initial addresses of the memories 25 and 26, the state transition circuit 54 sends the SET signal of "1" to the incremental points of the initial addresses of the memories 25 and 26 to the addresses. The generators 23 and 24 respectively output an address signal below each initial address from the address generators 23 and 24. Furthermore, the SET signal and the incremental signal for the initial address of the setting memory 28 are sent to the address generator 27 through the registers 31 and 32. This is to generate addresses at the desired timing. In this way, in the address generators 2 3 and 2 4, the state transition circuit 5 4 moves from the starting state to the calculating state after the initial address is set.

After sending the control signal to the operation department 1 0A, the MAC 1 0 a calculates the product (product sum) of the data stored in the temporary registers 3 5 and 36. On the other hand, the state transition circuit 54 has an internal register (not shown) that stores a certain setting, and the next bit signal sent from the address generator 2 4 is not equal to the above predetermined value. At this time, the SET signal of "0" is sent to the address generators 2 3 and 24, and the addition and subtraction signals and the increment signal are respectively sent to increase or decrease the address. Therefore, the data stored at the increased and decreased addresses are sent from the memory 25, 26 to the temporary registers 3 5, 36, respectively, and the product of the above data is calculated by the MAC 10a. At MAC 1 oa, the sum of this product and the sum of the previous ones is calculated. The product summing operation is continued until the address signal from the address generator 24 to the state transition circuit 54 is equal to the above-mentioned certain threshold. When the next bit address signal sent from the address generator 2 4 becomes the above-mentioned fixed value or lower, the state transition circuit 5 4 moves from the calculation state to the completion check state, and sends a timing signal to the comparator 5 3 at the same time. The timing signal is sent to the counter 51. Thus, the comparator 5 3 compares the data stored in the register 5 2 with the data DATA LENGTH sent from the control register 2 1 and sends the comparison result to the state transition circuit 5 4 ° If it sends to the counter 5 1 When a timing signal is received, the counter outputs the value stored in register 5 2 plus 1 and stored in register 5 2.

Because the state transition circuit 54 moves to the starting state, the initial addresses of the address generators 2 3 and 24 are set to "0" and "1" by the state transition circuit 54. Then, the data a 0 stored at the address “0” stored in the memory 25 is sent to the register 3 5, and the data bi stored at the address “1” of the memory 26 is sent to the register 3 6. Then, the state transition circuit 54 moves to the calculation state, and the state transition circuit 54 sends the control signal to MAC10a, and calculates the product ao.bi. At this time, since one of the next address signals sent from the address generator 2 4 is "1", the state transition circuit 5 4 outputs, which enables the output of the next address signal from the address generator 2 3 to be output.値 Increase “1”, and output the address signal of the next bit from the address generator 24. 値 Decrease the SET signal and the incremental signal of “1”, and force the subtraction signal. Then, the data a i stored at the address "1" stored in the memory 25 is stored in the register 35, and at the same time, the data bQ stored in the memory 26 at the address "0" is stored in the register 36. Next, a control signal is sent from the state transition circuit 54 to the MAC 1 0 a 'to calculate the product ai.bo at the time of the MAC 1 0 a operation ai.bo' 和 The product ai • b〇 and the product of the previous operation sum a0.bi (= A〇.bi + a 1 · b 〇) 〇 The state transition circuit 54 is sent from the address generator 24 to the next bit signal 値 equal to a certain 値 "〇", so the state transition circuit 5 4 Send the control signal to the MAC 1 0 a 'Via the temporary register 3 7.

The amount of calculation is 1 39 · 4mi ps, which can be greatly reduced. At this time, the area of the processing device of this embodiment is only increased by several K gates compared with the time of R I S C. In the processing device of this embodiment, when the cooperative processing unit is operating, the RIS C unit 1 cannot use the arithmetic unit used by the cooperative processing unit (for example, MAC10a, shift circuit, and rounding circuit in FIG. 2). However, regarding the order of using an arithmetic unit (not shown, but such as an adder, a comparator) which is not being used by the cooperative processing unit, the RISC unit 1 will perform ordinary operations, and will use an arithmetic unit which is used by the cooperative processing unit When the command arrives, the RISC unit 1 stops the operation, and when the cooperative processing unit completes the processing, the RI SC unit 1 starts the operation again, and the RI SC unit 1 and the processing unit can process in parallel. At the same time, in the conventional processing device, ALU 1 0 of RI SC section 1 sends the two input signals INI, IN2 as shown in FIG. 8 to the selected arithmetic unit via the selection circuit 102 according to the instruction signal. For example, one of the arithmetic units in the MAC 104a, the adder 104b, the shift circuit 104c, and the rounding circuit 104d outputs the operation result through the selection circuit 106, and when necessary, the above output can be used as one of the input signals INI and IN2. And enter again. In this regard, as shown in Figure 2, this embodiment is based on the calculations in ALU 1 〇A (please read the note on the back-item i to write this page ϋ 1 I ϋ 1 ϋ ^ OJ · ϋ —i 1 ϋ ϋ · 1 ί The paper size is in accordance with Chinese National Standard (CNS) A4 (210 X 297 mm) 20 ^ 498275 A7 B7 V. Description of the invention (18) Device, such as MAC10A, shift circuit 10b, round circuit 1 0 c is connected in series by the cooperative processing unit 2 0A. Therefore, compared with the traditional one, high-speed processing can be performed. At the same time, in the above embodiment, the arithmetic unit MAC is set only on the main processor side, but the corresponding processing is For calculation, when the arithmetic unit of the RISC unit is not enough, it can be prepared on the cooperative processing unit side as shown in Figure 9. The cooperative processing unit 2 0B shown in Figure 9 is the cooperative processing unit 2 shown in Figure 2. 0A is equipped with the architecture of MAC 3 8 and adder 39. MAC 3 8 performs the product and sum operation according to the 暂 stored in the temporary registers 3 5 and 36, and sends the operation result to the adder 3 9 and the adder 3 9 adds the output of MAC 1 0 a and the output of MA C 3 8 and sends the result of the addition to the temporary register 3 7. Furthermore, above The implementation form is described by taking an example of superimposition arithmetic processing and arithmetic processing of related functions. However, if the function of the main controller is changed and the function of the arithmetic unit 1 of the RISC unit 1 is changed at the same time, wave filtering processing or FET (Fast Fourier Transformation, etc. As described above, according to the present invention, not only high-speed processing, but also the overall occupied area can be reduced as much as possible.
