determining whether the read/write request is a read request;

determining whether the read request meets a first placement rule, when the read/write request is the read request; the first placement rule is that an address of the read request is different from an address in any write request in a write command queue;

acquiring data stored in a conflict address of the write request in the write command queue as a read data when the read request does not to meet the first placement rule;

determining whether the read request meets a second placement rule when the data read/write request meets the first placement rule; the second placement rule is that the resource identifier of the read request is different from the resource identifier in any write request in the write command queue; and

storing the read request in a read command queue based on a time of receiving when the read request does not to meet the second placement rule.

2. The method of claim 1 , wherein the data read/write request further comprises a priority level; the method further comprises:

storing the read request in the read command queue based on a third placement rule when the read request meets the second placement rule; the third placement rule is that the read command queue is inserted in the read command queue based on the priority level.

3. The method of claim 2 , wherein the method further comprises:

determining whether the write request meets a fourth placement rule when the data read/write request is a write request; the fourth placement rule is that the address and the resource identifier of the write request are different from an address and a resource identifier in any read request in the read command queue; and

storing the write request in a write command queue based on a time of receiving when the write request does not to meet the fourth placement rule.

4. The method of claim 3 , wherein the method further comprises:

storing the write request in the write command queue based on a fifth placement rule when the write request meets the fourth placement rule; the fifth placement rule is that the write request is inserted in the write command queue based on the priority level.

5. The method of claim 4 , wherein each first to fifth placement rules correspond a state identifier; the state identifier can be set to enabled or to disabled; when the state identifier is enabled, the corresponding placement rule is active, and when state identifier is disabled, the corresponding placement rule is disabled.

6. A data read/write processing apparatus; the data read/write processing apparatus comprising a non-transitory storage medium; the non-transitory storage medium storing program codes being executed by a processor, which forms modules; the modules comprising:

a receiving module, configured to receive a data read/write request; the data read/write request comprises a request type, data an address, and a resource identifier;

a determining module, configured to determine whether the read/write request is the read request; the determining module further determines whether the read request meets a first placement rule; the first placement rule is that the address of the read request is different from an address of each write request in the write command queue;

an acquiring module, configured to acquire the data stored in a conflict address of the write request in the write command queue as a read data when the read request does not to meet the first placement rule; and

an inserting module;

wherein the data read/write request comprises a resource identifier; the determining module further determines whether the read request meets a second placement rule when the data read/write request meets the first placement rule; the second placement rule is that the resource identifier of the read request is different from the resource identifier in any write request in the write command queue; when the read request does not to meet the second placement rule, the inserting module stores the read request in a read command queue based on a time of receiving.

7. The data read/write processing apparatus of claim 6 , wherein the data read/write request further comprises a priority level; when the read request meets the second placement rule, the inserting module stores the read request in the read command queue based on a third placement rule; the third placement rule is that the read request is inserted in the read command queue based on the priority level.

8. The data read/write processing apparatus of claim 7 , wherein the determining module further determines whether the write request meets a fourth placement rule when the data read/write request is a write request; the fourth placement rule is that the address and the resource identifier of the write request are different from an address and a resource identifier in any read request in the read command queue; when the write request does not to meet the fourth placement rule, the inserting module stores the write request in a write command queue based on a time of receiving.

9. The data read/write processing apparatus of claim 8 , wherein the inserting module further stores the write request in the write command queue based on a fifth placement rule; the fifth placement rule is that the write request is inserted in the write command queue based on the priority level.

10. The data read/write processing apparatus of claim 9 , wherein each first to fifth placement rules correspond a state identifier; the state identifier can be set to enabled or to disabled; when the state identifier is enabled, the corresponding placement rule is active, and when state identifier is disabled, the corresponding placement rule is disabled.

11. A non-transitory computer readable medium storing instructions being executed by a processor to implement following steps:

receiving a data read/write request; the data read/write request comprises a request type, data an address, and a resource identifier;

determining whether the read/write request is a read request;

determining whether the read request meets a first placement rule, when the read/write request is the read request; the first placement rule is that an address of the read request is different from an address in any write request in a write command queue;

acquiring data stored in a conflict address of the write request in the write command queue as a read data when the read request does not to meet the first placement rule;

determining whether the read request meets a second placement rule when the data read/write request meets the first placement rule; the second placement rule is that the resource identifier of the read request is different from the resource identifier in any write request in the write command queue; and

storing the read request in a read command queue based on a time of receiving when the read request does not to meet the second placement rule.

12. The computer readable medium of claim 11 , wherein the data read/write request further comprises a priority level; the computer readable medium further comprises:

storing the read request in the read command queue based on a third placement rule when the read request meets the second placement rule; the third placement rule is that the read request is inserted in the read command queue based on the priority level.

13. The computer readable medium of claim 12 , wherein the computer readable medium further comprises:

determining whether the write request meets a fourth placement rule when the data read/write request is a write request; the fourth placement rule is that the address and the resource identifier of the write request are different from an address and a resource identifier in any read request in the read command queue; and

storing the write request in a write command queue based on a time of receiving when the write request does not to meet the fourth placement rule.

14. The computer readable medium of claim 13 , wherein the computer readable medium further comprises:

storing the write request in the write command queue based on a fifth placement rule when the write request meets the fourth placement rule; the fifth placement rule is that the write request is inserted in the write command queue based on the priority level.

15. The computer readable medium of claim 14 , wherein each first to fifth placement rules correspond a state identifier; the state identifier can be set to enabled or to disabled; when the state identifier is enabled, the corresponding placement rule is active, and when state identifier is disabled, the corresponding placement rule is disabled.
