Embodiment
To combine the accompanying drawing in the embodiment of the invention below, the technical scheme in the embodiment of the invention is carried out clear, intactly description, obviously, described embodiment only is the present invention's part embodiment, rather than whole embodiment.Based on the embodiment among the present invention, those of ordinary skills are not making the every other embodiment that is obtained under the creative work prerequisite, all belong to the scope of the present invention's protection.
The embodiment of the invention provides a kind of method that is used for the faults inspection and corrects internal memory, and is as shown in Figure 1, may further comprise the steps:
101, the internal memory of the deal with data of processor in internal memory to be detected writes the detection data.
Because the ECC internal memory has the function of EDC error detection and correction, when the internal memory of the deal with data of processor in internal memory to be detected write the detection data, this ECC internal memory also can be write corresponding data simultaneously.
Such as, when the internal memory of the deal with data of processor in internal memory to be detected writes data 0x00000000_00001026, having no under the situation of fault at this ECC internal memory, this ECC internal memory also can be write data 0x55 simultaneously.
102, processor read in the ECC internal memory the ECC verification and.
In order to judge when the internal memory of the deal with data of processor in internal memory to be detected writes the detection data, the ECC verification that is written into simultaneously in the ECC internal memory and whether correct at first, need and be read the ECC verification that writes in this ECC internal memory.
103, processor judge said detection data and said ECC verification and between relation whether satisfy the ECC AES.
If said detection data and said ECC verification and between relation do not satisfy the ECC AES, execution in step 104; If the data in said detection data and the said ECC internal memory satisfy the ECC AES, execution in step 105.
The ECC verification that in having got access to the ECC internal memory, has write and after; The ECC verification that processor will write in the ECC internal memory and compare with detection data that internal memory to deal with data writes is judged the ECC verification in said detection data and the said ECC internal memory and whether is satisfied the ECC AES.
Such as; The ECC verification that from the ECC internal memory, reads and for 0x55, the detection data that write to the internal memory of deal with data are 0x00000000_00001026, according to preset algorithm; Satisfy the ECC AES between ECC verification and 0x55 and the data 0x00000000_00001026; Therefore, can explain that this ECC internal memory is normal, and any fault does not take place.
If; The ECC verification that from the ECC internal memory, reads and for 0x88, the detection data that write to the internal memory of deal with data are 0x00000000_00001026, according to the ECC AES; Do not satisfy the ECC AES between ECC verification and 0x55 and the data 0x00000000_00001026; Therefore, can explain that this ECC internal memory is abnormal, damage has taken place.
104, processor transmission error messages mistake occurs in order to indicate said ECC internal memory.
In order will to be damaged; The ECC internal memory that can not normally realize the ECC function distinguishes; ECC verification in judging said detection data and said ECC internal memory and when not satisfying the ECC AES needs to send error messages and mistake occur in order to indicate said ECC internal memory.
105, processor sends correct message, mistake do not occur in order to indicate said ECC internal memory, and all are normal.
What present embodiment provided is used for the faults inspection and corrects the internal memory method; Write the detection data through internal memory to deal with data; Read the ECC verification that writes in the ECC internal memory and compare, judge the ECC verification that writes among this ECC and whether correct with, the ECC verification that will read from this ECC internal memory with detecting data; And then judge that whether this ECC internal memory breaks down, and has realized the detection to the ECC function.

When detecting the internal memory non-fault of said deal with data, execution in step 202, if detect said deal with data in when having fault, flow process finishes.
202, the internal memory of the deal with data of processor in internal memory to be detected writes the detection data.
Because the ECC internal memory has the function of EDC error detection and correction, when the internal memory of the deal with data of processor in internal memory to be detected write the detection data, this ECC internal memory also can be write corresponding data simultaneously.
Such as, when the internal memory of the deal with data of processor in internal memory to be detected writes data 0x00000000_00001026, having no under the situation of fault at this ECC internal memory, this ECC internal memory also can be write data 0x55 simultaneously.
203, processor read in the ECC internal memory the ECC verification and.
In order to judge when the internal memory of the deal with data of processor in internal memory to be detected writes the detection data, the ECC verification that is written into simultaneously in the ECC internal memory and whether correct at first, need and be read the ECC verification that writes in this ECC internal memory.
204, processor judge said detection data and said ECC verification and between relation whether satisfy the ECC AES.
If said detection data and said ECC verification and between relation do not satisfy the ECC AES, execution in step 205; If the data in said detection data and the said ECC internal memory satisfy the ECC AES, execution in step 208.
The ECC verification that in having got access to the ECC internal memory, has write and after; The ECC verification that processor will write in the ECC internal memory and compare with detection data that internal memory to deal with data writes judges whether the data in said detection data and the said ECC internal memory satisfy the ECC AES.
Such as; The ECC verification that from the ECC internal memory, reads and for 0x55, the detection data that write to the internal memory of deal with data are 0x00000000_00001026, according to preset algorithm; Satisfy the ECC AES between ECC verification and 0x55 and the data 0x00000000_00001026; Therefore, can explain that this ECC internal memory is normal, and any fault does not take place.
If; The ECC verification that from the ECC internal memory, reads and for 0x88, the detection data that write to the internal memory of deal with data are 0x00000000_00001026, according to the ECC AES; Do not satisfy the ECC AES between ECC verification and 0x55 and the data 0x00000000_00001026; Therefore, can explain that this ECC internal memory is abnormal, damage has taken place.
205, processor is recorded in the error register misdata of said ECC internal memory fault address or said ECC internal memory fault address storage or the correct data that writes to said ECC internal memory fault address or above-mentioned combination in any.
Said error register can be the single-bit register, also can for or many bit register.
206, whether processor judges in the said error register wrong record.
In said error register during wrong record, execution in step 207.When in said error register, not having error logging, execution in step 208.
207, processor transmission error messages mistake occurs in order to indicate said ECC internal memory.
In order will to be damaged; The ECC internal memory that can not normally realize the ECC function distinguishes; ECC verification in judging said detection data and said ECC internal memory and when not satisfying the ECC AES needs to send error messages and mistake occur in order to indicate said ECC internal memory.
208, processor sends correct message and mistake do not occur in order to indicate said ECC internal memory, and all are normal.
