Shell-based memory read-write testing method

Abstract

The invention discloses a shell-based memory read-write testing method and belongs to the field of memory tests. The method comprises the following specific steps of: 1, ensuring that a tested memory is based on a linux kernel operating system, installing a memtester tool and logging on a running program; 2, presetting program parameters; 3, selecting modes which include a default current mode, a timing mode and a circulation mode, wherein the timing mode and the circulation mode are mutually exclusive, so that only one of the timing mode and the circulation mode can be selected; 4, setting a test environment of the memtester tool under the mode, and starting a memtester single-thread or multithread parallel test; 5, after the test is finished, viewing a test result file in which a test result and a test time record are recorded, and eliminating temporary files created in a program run process. During a process of testing memory read-write, an auxiliary test program runs, so that a series of complicated test operations such as parameter modification, repeated thread starting and result treatment are omitted, the test application limitation is broken, and the test efficiency is greatly increased.

Description

technical field [0001] The invention discloses a shell-based method for testing memory reading and writing, belonging to the field of memory testing. Specifically, the present invention relates to an automatic test method for reading and writing memory under a linux OS based on a shell language. Background technique [0002] Memory is a computer component that the CPU can address through the bus and perform read and write operations. With the continuous update of computer software and hardware technology, the size of computer memory (RAM) we usually refer to refers to the total capacity of memory. The read and write capabilities of the memory are an important factor in judging the memory. However, the current memory read and write stress test usually uses Memtester, which mainly captures memory errors and bad bits that are always at a high or low level. Size and times, random value, XOR comparison, subtraction, multiplication, division, and or operation are tested on the e...

Problems solved by technology

[0003] Aiming at the problems that the time cannot be set during the memtester test, and the multi-threaded parallel running test mode cannot be opened at one time, resulting in various disadvantages, the present invention provides a shell-based method for testing memory reading and writing, and realizes running auxiliary tests when testing memory reading and writing. The program eliminates a series of complicated test tasks such as parameter modification, multiple thread openings, and result processing, breaking the limitations of test applications, and does not require a series of complicated tasks such as manual operations and data sorting, which greatly improves test efficiency.
