Imaging reflective memory network shared memory data mapping correctness test method

Abstract

The invention provides an imaging reflective memory network shared memory data mapping correctness test method. The imaging reflective memory network shared memory data mapping correctness test method comprises nine steps. The imaging reflective memory network shared memory data mapping correctness test method is used for performing a comprehensive test on a local-memory area read-write link, a bottom layer network protocol firmware processing link and a physical layer send-receive link in the process of shared memory data mapping performed by all nodes in a reflective memory network. Not only can a user judge the correctness of the shared memory data mapping, but also an imaging feature is achieved, and the very intuitive observation of the regularity of error codes occurring when the data mapping is wrong is achieved. The imaging reflective memory network shared memory data mapping correctness test method is strong in intuition, rich in data change and capable of better simulating the real working condition of the reflective memory network. Any node in the reflective memory network can serve as a test sending node to start a test, and the other nodes serve as test forwarding nodes to check the test result. The imaging reflective memory network shared memory data mapping correctness test method has the advantages that the flexibility is strong, the coverage is good, and the test efficiency is greatly improved.

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
