Abstract
The invention relates to a method for testing memory via compressing data, which uses compression algorism to test the memory, wherein it comprises: first dividing the memory into at least three blocks as initial memory block, buffer memory block and target memory block; then storing the sample data into initial memory block; using compression algorism to compress the sample data while the buffer data is stored in buffer memory block; storing the compressed sample data into target memory block; at last, decompressing the compressed sample data; compressing decompressed sample data with original compress data, to judge if the memory has mistake.
Description
Technical field
The present invention relates to a kind of method of testing memory, particularly a kind of by the method for data compression process with testing memory.
Background technology
The algorithm of testing memory has many kinds, and the fundamental purpose of these algorithms is the situations that may make mistakes for emulation memory, to demonstrate when the machine run mistake that the storer in the use may occur.
General testing algorithm is when single-threaded operation, give the load and the insufficient pressure of storer, therefore can't test out when storer and be under the high pressure, the mistake that can occur, common algorithm is in some specific sample program write store, then read checking again, these algorithms do not carry out repeatedly readwrite tests to storer, it is high and calculated amount is less to give the load of storer, so when single-threaded operation, give the insufficient pressure of storer and central processing unit, just can't test out under high pressure conditions whether mistake can occur.
The mode of existing testing memory has been given the tester prompting, come testing memory if adopt emulation to carry out image file, just can learn from process whether storer is wrong, the back is found by analysis, compression process in the implementation is exerted pressure bigger to storer, this is worth the direction of inquiring into for one of researchist.
Summary of the invention
It is a kind of by the method for data compression process with testing memory that technical matters to be solved by this invention is to provide, because compression process can be carried out the repeated multiple times read-write to certain address in most of storer, so storer is applied big pressure, the validity of storer when simultaneous verification is read and write repeatedly is to solve the existing in prior technology problem.
Therefore, for achieving the above object, disclosed in this invention a kind of by the method for data compression process with testing memory, utilize compression algorithm, to the storer test of exerting pressure, the method comprises the following step: storer is divided at least three partly: an initial memory block, a memory buffer piece and a target memory block; Compressible sample data is deposited in the start memory piece; Utilize compression algorithm, sample data is carried out compressed action, in the memory buffer piece, store the middle transition data of the sample data in the compression process; Sample data after compression finished is deposited in the target memory block; The action that the sample data that leaves in after the compression of target memory block is decompressed; And sample data after the contrast decompression and the preceding sample data of compression.
Adopt provided by the invention by the method for data compression process with testing memory, utilize compression algorithm, data in the storer are carried out the compression and decompression test, and before the checking compression with decompression after data whether consistent, because compression process can be carried out the repeated multiple times read-write to certain address in most of storer, so can apply big pressure, can verify the validity of storer when reading and writing repeatedly simultaneously, come testing memory whether wrong storer.
Below in embodiment, be described in detail detailed features of the present invention and advantage.
Description of drawings
Fig. 1 is of the present invention by the method flow diagram of data compression process with testing memory.
Wherein, Reference numeral:
Sample data after step 140 is finished compression is deposited in target memory block;
Whether the preceding sample data of the sample data after step 160 contrast decompresses and compression is consistent;
Embodiment
For making purpose of the present invention, structure, feature and function thereof there are further understanding, cooperate embodiment to be described in detail as follows now.Above about content of the present invention explanation and the explanation of following embodiment in order to demonstration with explain principle of the present invention, and provide claim of the present invention further to explain.
As shown in Figure 1, utilize compression algorithm for of the present invention by the method flow diagram of data compression process with testing memory, (Lempel-Ziv 77 as blue Bo-Li Fu 77; Lz77) algorithm is to the storer test of exerting pressure.
At first, storer is divided begin at least together memory block, a memory buffer piece and a target memory block (step 110), wherein the start memory piece is taken as identical with the size of target memory block, owing to can't predict ratio of compression, so suppose the compression result of worst be for ratio of compression be 1, then, sample data is deposited in the start memory piece (step 120), this sample data is necessary for compressible data.
By compression algorithm, sample data is carried out compressed action, in the memory buffer piece, store the middle transition data (step 130) of the sample data in the compression process, the sample data after again compression being finished leaves target memory block (step 140) in.
Afterwards, with the action (step 150) that the sample data of depositing in after the compression of target memory block decompresses, last, whether the preceding sample data of the sample data after contrast decompresses and compression consistent (step 160), when both data are inconsistent, judge storer wrong (step 180); And when both data consistents, judge storer normal (step 170).
After the step of judging storer normal (step 170), continue to change the division position of start memory piece, memory buffer piece and target memory block, and repeat whole testing procedures (step 190), this method of testing can effectively test out mistake.
The present invention utilizes compression algorithm, and the data in the storer are carried out compression and decompression tests, and before the checking compression with decompression after data whether consistent, come testing memory whether wrong storer is applied bigger pressure.
Because, several bytes in the sample data are after overcompression, can write repeatedly in certain several position (bit) of a certain byte (byte), can read a byte earlier before writing at every turn, revise several position after, write once more in this byte, thereby form the test of reading and writing certain storage address repeatedly, exert pressure to storer, similarly, the process of decompression also is a similar phenomenon.
Certainly; the present invention also can have other various embodiments; under the situation that does not deviate from spirit of the present invention and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to the present invention, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of the present invention.
