On the contrary, these embodiments are provided to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.
[0032] The internal storage space of a chip is usually accessed by two or more processing components. Data is written into the storage space from one processing component and read out by another processing component. The access of the two processing components to the storage space usually requires the intervention of the CPU for upper-level management. Since the CPU needs to intervene for upper-level management, the data throughput efficiency of the storage space is reduced.
[0033] Therefore, it is currently necessary to solve the problem that the CPU needs to intervene to perform upper-level management when the processing unit accesses the storage space, which reduces the data throughput efficiency of the storage space. In view of this, the present application proposes a storage space data reading and writing method, device, storage medium and program product.

[0038] In one embodiment, the processor 1001 may be used to call a storage space data reading and writing program stored in the memory 1005, and execute the method including:
[0039] Perform the following operations on each storage unit in turn until all storage units have completed the read and write operations:
[0040] After writing the data into the storage unit through the writing component, setting the idle and busy flag bit corresponding to the storage unit to a writing state;
[0041] When the write state is detected by the read component and a preset condition is reached, all the data of the storage unit are read out, and the idle / busy flag of the storage unit is restored to an idle state.

[0043] The preset condition is that the writing component writes data into the next storage unit and sets the idle / busy flag corresponding to the next storage unit to a writing state.
[0044] In one embodiment, the processor 1001 may be used to call a storage space data reading and writing program stored in the memory 1005, and execute the method including:
[0045] The readout component is provided with a waiting flag bit corresponding to each of the storage units, and the waiting flag bit is used to indicate that the storage unit is in an unwritten state or a waiting read state; after the step of setting the idle busy flag bit corresponding to the storage unit to a written state after the data is written to the storage unit by the writing component, the step further includes:
[0046] The readout component sets the waiting flag corresponding to the storage unit to a waiting readout state.
[0047] In one embodiment, the processor 1001 may be used to call a storage space data reading and writing program stored in the memory 1005, and execute the method including:
[0048] After the step of detecting the write state through the reading component and reaching a preset condition, reading all the data of the storage unit and restoring the idle and busy flag of the storage unit to an idle state, the method further includes:
[0049] The readout component sets the waiting flag corresponding to the storage unit to an unwritten state.
[0050] In one embodiment, the processor 1001 may be used to call a storage space data reading and writing program stored in the memory 1005, and execute the method including:
[0051] After the data is written into the storage unit by the writing component, the idle / busy flag bit corresponding to the storage unit is set to a writing state, including:
[0052] Writing data into the storage unit through the writing component, and checking the validity of the data;
[0053] If the data is valid, the busy / idle flag bit corresponding to the storage unit is set to a write state.
[0054] In one embodiment, the processor 1001 may be used to call a storage space data reading and writing program stored in the memory 1005, and execute the method including: the checking the validity of the data includes:

[0056] Performing an XOR check on the data to check the validity of the data; or
[0057] A cyclic redundancy check is performed on the data to check the validity of the data.
[0058] The storage space data reading and writing device of the present application sets a busy and idle flag in the storage unit to indicate that the data in the storage unit is in a write state or an idle state, so that the writing component sets the busy and idle flag to the write state after writing the data into the storage unit, and the reading component reads the data of the storage unit in time after detecting the write state, and then the reading component restores the busy and idle flag to the idle state. The storage space data reading and writing device improves the storage space data throughput efficiency by setting the busy and idle flag as a flag for judging whether the storage unit is busy or idle.
[0059] Please refer to Figure 2 Based on the hardware architecture of the storage space data reading and writing device, the following is an embodiment of the storage space data reading and writing method of the present application. The storage space includes multiple continuous storage units of a preset length, and each storage unit is provided with a corresponding busy or idle flag to indicate that the data in the storage unit is in a writing state or an idle state.
[0060] It should be noted that the storage space is used to store data. The storage space is in units of a certain fixed length. For example, it can be 512MB, 1T, etc. In this embodiment, the storage space is divided into a plurality of continuous storage units of preset lengths. It is understandable that the preset length here can be set according to actual conditions, for example, it can be flexibly set to 512Byte, 1024Byte, etc. It should be understood that the specific values of the storage units listed above are only for those skilled in the art to better understand the technical solution of the present application, and should not be understood as a specific limitation on the length of the storage units of the present application.
[0061] Busy / idle flag: In this embodiment, each storage unit is provided with a corresponding busy / idle flag. The busy / idle flag is used to indicate that the data in the storage unit is in a write state or an idle state. The busy / idle flag can be set at the beginning, end or other position of the storage unit. The specific position of the busy / idle flag in the storage unit is not limited here.
[0062] In some embodiments, the busy / idle flag bit can be set to 1, which indicates that the data in this storage unit has been written by the write processing component and can be read by the read processing component. Conversely, the busy / idle flag bit can be set to 0.
[0063] It is understandable that in other embodiments, a multi-bit binary number can be set to indicate the write state or idle state. For example, a two-bit binary number can be used to indicate that the storage unit is in the write state or idle state. 01 indicates that the data in this storage unit has been written by the write processing component and can be read by the read processing component. On the contrary, the idle and busy flag bit can be set to 10, which indicates that this storage unit is idle and data can be written to this storage unit. Of course, the write state or idle state of the idle and busy flag bit can also be set by using a binary number with more bits.
[0064] The storage space data reading and writing method comprises the following steps:
[0065] Perform the following operations on each storage unit in turn until all storage units have completed the read and write operations:
[0066] S100, after writing data into the storage unit through the writing component, setting the idle busy flag bit corresponding to the storage unit to a writing state;
[0067] It should be noted that the writing component (also called the writing processing component) of the present application is responsible for writing data to the storage space. The reading component (also called the reading processing component) of the present application is responsible for reading data from the storage space. The writing component and the reading component can be various components that can realize writing data to the storage space and reading data from the storage space.
[0068] After the writing component writes the data into the storage unit, by setting the idle and busy flag corresponding to the storage unit to the writing state (for example, setting the idle and busy flag to 1), the idle and busy state of the storage unit can be promptly indicated, so that the reading component can promptly know the idle and busy state of the storage unit, and the reading component can promptly read the data of the storage unit, so as to improve the data throughput efficiency of the storage space.
[0069] S200, when the write state is detected by the read component and a preset condition is reached, all the data of the storage unit are read out, and the idle / busy flag of the storage unit is restored to an idle state.
[0070] The readout component detects the write state, indicating that the storage unit corresponding to the write state is in a data write state. After the preset condition is met, the readout component can read out all the data of the storage unit corresponding to the write state, thereby completing the writing and reading of a storage unit.
[0071] It should be noted that after the readout component reads the data of the storage unit, the busy / idle flag of the storage unit is restored to the idle state, so as to display the idle state in the storage unit in time and prevent the readout component from mistakenly reading a storage unit with no written data.
[0072] It is worth mentioning that in order to further improve the data throughput efficiency of storage space. Please refer to Figure 3 , the preset condition can be set as the writing component writing data into the next storage unit, and setting the busy / idle flag corresponding to the next storage unit to the writing state. That is, after the next storage unit completes writing data, the reading component reads the data of the previous storage unit. After the writing component completes writing data to the next storage unit, the reading component reads the data of the previous unit. Such alternating operation can realize the access of the storage space by the processing component without the intervention of the CPU (i.e., central processing unit), and the upper-level management without the intervention of the CPU, which saves the time cost of CPU intervention management and improves the data throughput efficiency of the storage space.
[0073] The following is an explanation using a typical embodiment. For example, there are storage unit 0, storage unit 1, storage unit 2, storage unit 3, ...
[0074] During the time from T0 to T1: the writing component writes data to storage unit 0, and after the data of storage unit 0 is fully written, the idle and busy flag is set to 1.
[0075] During the time period from T1 to T2: the write component writes data to storage unit 1, and after storage unit 1 is fully written, the busy / idle flag is set to 1. The read component reads data from storage unit 0, and after all the data in storage unit 0 is read, the busy / idle flag is cleared to 0.
[0076] During the time period from T2 to T3: the write component writes data to storage unit 2, and after storage unit 2 is fully written, the busy and idle flag is set to 1. The read processing component reads data from storage unit 1, and after all the data in storage unit 1 is read, the busy and idle flag is cleared to 0.
[0077] And so on, the read and write operations of the remaining storage units in the storage space are completed.
[0078] It should be noted that there are two situations that affect the data reading and writing speed: one is that the writing component is slower than the reading component; the other is that the writing component is faster than the reading component. The specific data reading and writing speed depends on the processing component with the slower processing speed.
[0079] This embodiment sets a busy or idle flag in the storage unit to indicate that the data in the storage unit is in a write state or an idle state, so that the write component sets the busy or idle flag to the write state after writing the data into the storage unit, and the read component reads the data of the storage unit in time after detecting the write state, and then the read component restores the busy or idle flag to the idle state. This embodiment sets the busy or idle flag as a flag for judging whether the storage unit is busy or idle, so that the processing component accesses the storage space without the CPU intervening for upper-level management, thereby saving the time cost of CPU intervention management and improving the data throughput efficiency of the storage space.
[0080] Based on the same invention concept, please refer to Figure 4 , the present application also proposes a second embodiment, which is based on the first embodiment.
[0081] Embodiment 2
[0082] The readout component is provided with a waiting flag bit corresponding to each of the storage units, and the waiting flag bit is used to indicate that the storage unit is in an unwritten state or a waiting readout state;
[0083] The storage space data reading and writing method of this embodiment includes:
[0084] S100, after writing data into the storage unit through the writing component, setting the idle busy flag bit corresponding to the storage unit to a writing state;
[0085] S300, setting the waiting flag corresponding to the storage unit to a waiting read state by the reading component;
[0086] S200, when the write state is detected by the read component and a preset condition is reached, all the data of the storage unit are read out, and the idle / busy flag of the storage unit is restored to an idle state.
[0087] The following is an explanation using a typical embodiment. For example, there are storage unit 0, storage unit 1, storage unit 2, storage unit 3, ...
[0088] During the time period from T0 to T1: the write component writes data to storage unit 0, and after the storage unit 0 is fully written, the busy flag is set to 1. The waiting flag of the read component is 1 (i.e., waiting for readout), i.e., waiting for valid data.
[0089] During the time period from T1 to T2: the write component writes data to storage unit 1, and after the data in storage unit 1 is fully written, the busy and idle flag is set to 1. The read component reads data from storage unit 0, and after all the data in storage unit 0 is read, the busy and idle flag is cleared to 0, and the wait flag of storage unit 1 is set to 1, that is, waiting for valid data from storage unit 1.
[0090] During the time period from T2 to T3: the write component writes data to storage unit 2, and after the data in storage unit 2 is fully written, the busy and idle flag is set to 1. The read processing component reads data from storage unit 1, and after all the data in storage unit 1 is read, the busy and idle flag is cleared to 0, and the waiting flag of storage unit 2 is set to 1, that is, waiting for valid data from storage unit 2.
[0091] And so on, the read and write operations of the remaining storage units in the storage space are completed.
[0092] By providing the readout component with a waiting flag corresponding to each of the storage units, the readout component can read the data of the storage units one by one, thereby improving the orderliness of the readout component in reading the stored data, thereby improving the data throughput efficiency of the storage space.
[0093] Please refer to Figure 5 In some embodiments, after step S200, the following steps are further included:
[0094] S400, setting the waiting flag corresponding to the storage unit to an unwritten state through the reading component.
[0095] After the readout component reads out the storage unit, the readout component sets the waiting flag corresponding to the storage unit to an unwritten state. For example, after the readout component reads out data from storage unit 0, the waiting flag corresponding to storage unit 0 is set from 1 to 0 (i.e., an unwritten state). This prevents the readout component from mistakenly reading data from the storage unit that has just read data. This improves the orderliness of the readout component in reading stored data and improves the data throughput efficiency of the storage space.
[0096] Based on the same invention concept, please refer to Figure 6 , the present application also proposes a third embodiment, which is based on the first embodiment.
[0097] Embodiment 3
[0098] Step S100 specifically includes:
[0099] S110, writing data into the storage unit through the writing component, and checking the validity of the data;
[0100] S120: If the data is valid, the idle / busy flag corresponding to the storage unit is set to a write state.
[0101] It can be understood that after the writing component writes the data into the storage unit, the validity of the data is first checked. If the data is valid, the idle and busy flag corresponding to the storage unit is set to the write state to avoid non-target data, garbled data or erroneous data from being input into the storage unit, thereby improving the accuracy of the data stored in the storage space.
[0102] Specifically, checking the validity of the data can be achieved in any of the following ways.
[0103] In some embodiments, the data is parsed to obtain identity verification information, and the identity verification information is compared with preset identity information to verify the validity of the data.
[0104] The data usually carries identity verification information indicating the type of data. The identity verification information can be various numbers, English letters, characters, or a combination of at least two of them. And the identity verification information is often a specific position in the data, and the identity verification information can be obtained by parsing the specific position in the data. By comparing the parsed identity verification information with the preset identity information, if the two match, it means that the data written by the writing component is valid.
[0105] In some other embodiments, the data is XOR-checked to check the validity of the data. Specifically, a byte at a specific position in the data is XOR-ed in sequence to finally obtain a check code, and the check code is compared with a preset check code. If they are the same, it means that there is no communication error in the data in the storage unit during communication and the data is valid; if they are different, it means that there is a communication error in the data in the storage unit during communication and the data is invalid.
[0106] In some other embodiments, a cyclic redundancy check may be performed on the data to check the validity of the data. It is worth mentioning that the validity of the data in the storage unit may also be checked by LRC check method, Gray code check method, and sum check method.
[0107] The present application also proposes a computer-readable storage medium, which stores one or more programs. The one or more programs can be executed by one or more processors to implement the steps in the storage space data reading and writing method.
[0108] The present invention also proposes a computer program product, including a computer program, which, when executed by a processor, implements the steps of the storage space data reading and writing method as described above.
