Embodiment Construction

[0021] Embodiments of the invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the figures are exemplary only for explaining the present invention and should not be construed as limiting the present invention.

[0022] One embodiment of the present invention is to build a mirror image of the debugged storage device on other high-speed storage media (Media), and the read and write requests sent by the operating system are not only handed over to the debugged storage device at the driver layer, or called the debugged In addition to disk processing, a copy is also sent to the mirror. If a certain location of the device has been written, then when reading again, it is necessary to read the data at the corresponding location from the mirror, and compare the two to determine the correctness of the data on the device. As an embodiment of the present invention, the previous sequence of...

Abstract

The invention provides method and system for debugging hardware of a memory system. The method comprises the following steps of: establishing an image of a debugged memory device, wherein memory units of the image are mapped with memory units of the debugged memory device one by one; reading and writing the debugged memory device and the image; and positioning the defect of the debugged memory device according to the image. The method and the system for debugging the hardware of the memory device can assist the hardware debugging of a high-speed device, lower the debugging difficulty and shorten the development period of the hardware.

Description

technical field [0001] The present invention relates to the technical field of computers, and more particularly relates to hardware debugging technology of storage devices. Background technique [0002] With the development of material science and the high demand for storage bandwidth and delay in some applications, some new high-speed storage devices have been gradually researched and developed, such as flash memory (Flash Memory), solid state disk (SSD: Solid State Disk) and memory-based Granular storage devices, etc., to make up for the lack of disk performance. This type of product does not have enough technical accumulation, and its high bandwidth and low latency characteristics are also prone to bugs. A defect usually corresponds to a certain read-write pattern (Pattern), and developers often need to use this sequence to reproduce the defect for debugging. [0003] In order to comprehensively test and debug a storage product under development, using a definite read a...
