A Graphical Reflective Memory Network Shared Storage Area Data Mapping Correctness Testing Method

Abstract

A graphical reflective memory network shared storage area data mapping correctness testing method, which has nine major steps. This test method is used to comprehensively test the reading and writing links of the local storage area, the processing link of the underlying network protocol firmware, and the sending and receiving link of the physical layer during the data mapping process of the shared storage area of ​​all nodes in the reflective memory network. It not only allows the user to judge the correctness of the data mapping in the shared storage area, but also has the characteristics of graphics, which can intuitively observe the regularity of code errors when the data mapping is wrong. The graphical test method adopted by the present invention has strong intuitiveness, rich data changes, and can better simulate the actual working conditions of the reflective memory network. Any node in the reflective memory network can be used as a test sending node to initiate a test, and other nodes can be used as a test forwarding node to verify the test results. Its test has strong flexibility and good coverage, which greatly improves the efficiency of testing.

Description

technical field [0001] The invention relates to an image-based method for testing the correctness of data mapping in a shared storage area of ​​a reflective memory network. The test method can obtain data in a selected data source block in a shared storage area of ​​a reflective memory network in real time and convert it into a color image . According to the working principle of reflective memory network, the data mapping result is displayed to the operator in a graphical way. This method can not only intuitively discover the correctness of the reflective memory network data mapping process, such as bit errors and the rules of bit errors, the time when data digits are wrong, whether data errors occur continuously, etc., but also test each reflective memory node card For the retention of data in the shared storage area, it is also possible to test the real-time performance of sharing data between multiple hosts through the reflective memory network. The invention belongs to t...

Problems solved by technology

However, currently there are very few test methods for reflective memory networks, basically all of which are to test the real-time performance of data mapping, such as the design of real-time network systems based on reflective memory (see the 24th issue of "Journal of Xi'an Engineering University" in 2010, No. Volume 1); in addition, some research work explores the application of other network characteristics in reflective memory networks, such as the research and implementation of data group propagation mechanism in reflective memory networks (see the 21st issue of "Dianle Design Engineering" in 2013, No. Six volumes), mainly discussing the realization of Ethernet multicast communication mechanism in reflective memory network; there are very few research works discussing the realization of reflective memory network, such as the development of real-time network interface card based on reflective memory technology (see Harbin Industrial University 2010 master thesis), focusing on the realization of the PCI interface
