Memory stability verification method and device

Abstract

The invention provides a method and device for verifying memory stability. The memory is divided into software system memory and hardware system memory. The size of the software system memory is the minimum memory value required by the operating system to work. The hardware system memory In order to break away from the memory of the software operating system, the method includes: filling data into the hardware system memory; reading data from the hardware system memory; when the read data is consistent with the filled data, judging that the The hardware system memory is stable; when the read data is inconsistent with the filled data, it is determined that the hardware system memory is unstable. The invention can independently verify the memory stability of the hardware system independently of the memory management of the software system.

Description

technical field [0001] The invention relates to the technical field of computer system verification, in particular to a memory stability verification method and device. Background technique [0002] In a computer system, memory is one of the key factors determining the performance of the whole machine. With the rapid development of microelectronics technology, the performance of processors has doubled, and the performance requirements for memory are also getting higher and higher. The reliability of memory storage performance depends on the correct design and testing of the memory. The main goal of memory testing is to verify that each storage bit on the memory can reliably store data. Functional testing of memory consists of a series of reads and writes performed by digital test equipment Job composition, after each execution of the read job, the test system compares the read data with the expected value. [0003] Currently, there are two methods for memory testing in the...

Problems solved by technology

[0005] At present, although the above two methods can be used to verify the memory stability of the system under the MIPS platform vxWorks operating system, they cannot be separated from the software system memory management when verifying the stability of the hardware system memory.

When there is a problem with the memory system, it is impossible to locate whether it is a memory stability problem of the hardware system or a memory stability problem of the software system.
