Abstract
AbstractBeing the computing center of satellite navigation system, application processing system is charged with lots of high-precision computing tasks including orbit determining, time synchronizing, ionosphere model calculating, difference and integrity parameters processing, and it has a large number of features, such as mass and multi-sort data, heavy computing tasks, high precision of calculation, so there are much rapid mass-data transmissions between different processes. As the primary means of communication between processes, shared memory has the characteristic of rapid mass-data transmission. Therefore there are lots of shared memories to transfer data among different processes in application processing system. This paper describes the realization principle of shared memory, focuses on parsing the blocking shared memory design principle, achieves the blocking shared memory template class based on the principle, and through the test verifies the reliability of the template class.KeywordsBlocking shared memorySatellite navigationApplication processing system
