| Abstract: |
| In a multi - process real time application, for the purpose of resource sharing between two processes, transferring information is necessary. This paper introduces a method based on signal mechanism which is used to transfer information speedily between two processes in the UNIX real time application. This method can improve the real time performance. |
| Key words: computer communication data transmission signal mechanism sub - signal code - combined timing precision |
