In this alternative, the encryption/decryption target rate, the number of encryption/decryption modules used, and the storage unit multiplexing signal are obtained. Therefore, in the application, the encryption and decryption target rate, the number of the encryption and decryption modules and the storage unit multiplexing signal are obtained from the outside. The encryption and decryption target rate is used for representing the speed during encryption and decryption calculation, the number of encryption and decryption modules used is used for representing the number of modules required to be used in the encryption and decryption process, and the storage unit multiplexing signal is used for representing the number or the address of the storage units required to be multiplexed.

and 2, setting a target clock frequency for the first encryption and decryption calculation module.

In the alternative scheme, firstly, clock frequency calculation is carried out on an encryption and decryption target rate to obtain a target clock frequency; then, a target clock frequency is set for the first encryption/decryption calculation module. Therefore, in the alternative, after the encryption and decryption target rate is determined, the clock frequency can be calculated to obtain the target clock frequency.

The resource scheduling method of an encryption and decryption system provided by the present application is further described below by using another specific embodiment.
Referring to fig. 2, fig. 2 is a schematic structural diagram of an encryption and decryption system according to an embodiment of the present disclosure.
The encryption and decryption system in this embodiment may include a parameter adaptation module, a dynamic management module, and an encryption and decryption calculation module array.
The input signal of the parameter adaptation module comprises an encryption and decryption target rate H (H is greater than or equal to 0 and less than or equal to H, H is the maximum encryption and decryption rate which can be completed by the system), the number N of the encryption and decryption modules occupied by the encryption and decryption modules (N is greater than or equal to 1 and less than or equal to N, N encryption and decryption computing modules are shared in the encryption and decryption computing module array), an SRAM multiplexing signal Smux1 (N bit signal, when the value of the nth bit is 1, the multiplexing of the SRAM in the nth encryption and decryption computing module is indicated), an output signal has a parameter adaptation result R (N bit signal, which indicates whether the input parameter can be successfully adapted, the N bits are all 0, the N bits are failed, otherwise, the nth bit is 1, the nth encryption and decryption computing module is used for encryption and decryption computation), an operating frequency Freq of the encryption and decryption module, and an SRAM control signal Smux2 (the same as Smux 1). The input signals H and N of the parameter adaptation module need to satisfy that H/H is larger than or equal to N, the total number of 1 in the Smux1 signal is smaller than or equal to N-N, and the parameter adaptation module can complete adaptation.
The interface signals of the dynamic management module include a parameter adaptation result R, an SRAM control signal Smux2, an encryption/decryption module operating frequency Freq, an output clock signal Clk, an output power control signal P (N-bit signal, where the nth bit is 1, which indicates that the nth encryption/decryption computing module is normally powered, and 0 indicates that the nth encryption/decryption computing module is powered off, and the signal P is composed of 1 of R and Smux 2), N sets of SRAM external interface signals SRAME _ N (each set of interface signals includes an enable signal, an address signal, a data signal, etc. of a corresponding SRAM), and N sets of SRAM internal interface signals SRAMI _ N (each set of interface signals includes an enable signal, an address signal, a data signal, etc. of a corresponding SRAM). The Freq signal output by the parameter adaptation module is input into the dynamic management module, and the dynamic management module adjusts and outputs the clock signal Clk (a DPLL mode can be adopted) according to the Freq value, so that the actual frequency of the Clk signal is consistent with the Freq value. The output signal P of the dynamic management module directly controls the power supplies of the N encryption and decryption calculation modules and only supplies power for the encryption and decryption calculation module which carries out encryption and decryption calculation and SRAM multiplexing.
The encryption and decryption computing module array comprises N encryption and decryption computing modules and 1 encryption and decryption resource scheduling module. The encryption and decryption computing module is used for carrying out actual encryption and decryption operation, and the encryption and decryption resource scheduling module has the main function of scheduling the corresponding encryption and decryption computing module to work according to the parameter adaptation result R, and comprises the steps of distributing data to be processed to different encryption and decryption computing modules and outputting processed data output by different encryption and decryption computing modules in sequence.
Based on the structure of the encryption and decryption system, the operation steps in this embodiment may include:
step 3, the dynamic management module adjusts the frequency value of the clock signal Clk according to the Freq value and outputs the frequency value to the encryption and decryption calculation module array;
step 4, enabling the corresponding SRAME _ N and SRAMI _ N signals by the dynamic management module according to the position corresponding to 1 in the Smux2 with N bits, that is, when the nth bit in the Smux2 is 1, enabling SRAME _ N and SRAMI _ N, and enabling the remaining SRAME _ m and SRAMI _ m to be in a non-enabled state (the mth bit in the Smux2 is 0), after SRAME _ N and SRAMI _ N are enabled, connecting SRAME _ N [0 ] and SRAMI _ N [ 0;
step 5, the encryption and decryption computing module array turns off the power supply of the unused encryption and decryption computing module according to the P value in the step 2, and when the value corresponding to the nth bit in the N-bit P value is 0, the power supply of the nth encryption and decryption computing module is turned off;
step 6, the encryption and decryption computing module without the power supply being turned off works under the Clk output in the step 3;
step 7, an encryption and decryption resource scheduling module in the encryption and decryption computing module array schedules input data to be processed to an effective encryption and decryption computing module according to the R value (the scheduling can be performed according to a sequence from low to high, if the 1 st, 2 nd and 3 rd bits of R are 1, the 1 st group of data to be processed is scheduled to the 1 st encryption and decryption computing module, the 2 nd group of data to be processed is scheduled to the 2 nd encryption and decryption computing module, and the 3 rd group of data to be processed is scheduled to the 3 rd encryption and decryption computing module);
and 8, after the encryption and decryption calculation module finishes the encryption and decryption calculation, the encryption and decryption resource scheduling module outputs the encryption and decryption results of the modules according to the input sequence (first in first out, the 1 st group outputs after the 1 st group of data to be processed is calculated, the 2 nd group outputs after the 2 nd group of data to be processed is calculated, and the like). Therefore, part of encryption and decryption computing modules can work under the Clk to complete encryption and decryption computing, and instantaneous power consumption is effectively reduced under the condition that the encryption and decryption throughput requirements are met; and the SRAM in the encryption and decryption computing module corresponding to Smux2 can complete read-write access through the SRAME _ n signal, so that idle encryption and decryption computing module resources are effectively utilized.
It can be seen that, in this embodiment, the obtained control parameter divides a plurality of encryption and decryption calculation modules in the encryption and decryption system into a first encryption and decryption calculation module and a second encryption and decryption calculation module, and then the first encryption and decryption calculation module is used for performing encryption and decryption calculation, and a storage unit of the second encryption and decryption calculation module is multiplexed, thereby avoiding waste of storage resources and improving the resource utilization rate of the encryption and decryption system.
